    Diet-microbiome interactions may be moderators of human metabolism. Does this mean that with the ingestion of a capsule with the mix of the relevant strains we can colonize our gut with beneficial organisms that prevent us from obesity, cancer, cardiovascular or metabolic diseases are obesity type 2 diabetes, ect….? This question will be considered and the hypothesis of the “dietary fiber gap” is proposed to (partly) explain the (causal?) relationship between the loss of diversity of the gut microbiome and the incidence of “modern diseases”, like obesity and type 2 diabetes. Implications for public health messages will be discussed.

    Dietary or metabolic endotoxemia is a condition that affects approximately 1/3 of individuals living in Western society. It is characterized by increased serum endotoxin concentration during the first five hours of the post-prandial period following consumption of a meal with a high-fat, high-calorie content. Long-term repeated dietary endotoxemia may increase the risk of developing a variety of chronic diseases. Of the available treatments, oral probiotic supplementation has been purported to reduce gastrointestinal permeability to endotoxin, which in theory should suppress the dietary endotoxin response. The purpose of this study was to determine if 30-d of oral probiotic supplementation could reduce post-prandial dietary endotoxemia in “responder” subjects. Apparently healthy men and women (N=75) were screened for post-prandial dietary endotoxemia. Subjects whose serum endotoxin concentration increased by at least 5-fold from pre-meal levels at 5-h post-prandial were considered “responders” and were randomized to receive either placebo (rice flour) or multi-strain probiotic supplement (Bacillus indicus (H36), Bacillus subtilis (H58), Bacillus coagulans, and Bacillus licheniformis, and Bacillus clausii) for 30-d. The dietary endotoxemia test was repeated at the conclusion of the supplementation period. Dietary endotoxin (LAL) and triglycerides (enzymatic) were measured using an automated chemistry analyzer. Serum disease risk biomarkers were measured using bead-based multiplex assays as secondary, exploratory measures. Data were statistically analyzed using repeated measures ANOVA and a P < 0.05. We found that probiotic supplementation was associated with a 42% reduction in endotoxin (P=0.011) and 24% reduction in triglyceride (P=0.004) in postprandial period Placebo subjects presented with a 36% increase in endotoxin and 5% decrease in triglycerides over the same postprandial period. We also found that probiotic supplementation was associated with significant post-prandial reductions in IL-12p70 (P=0.017), IL-1β (P=0.020), and ghrelin (P=0.017) compared to placebo subjects. The key findings of the present study, were that oral probiotic supplementation reduced responses that were consistent with “leaky gut syndrome” and transient reductions in chronic/metabolic disease risk.

    Many Lactobacillus species have been successfully used in clinical trials to treat diarrhea in children. However, mechanisms underlying anti-diarrheal effects of probiotics are not well understood. Recent studies from our group have shown that certain lactobacillus and bifidobacterial species upregulated electrolyteabsorption in the intestine.Since Intestinal epithelial apical membrane NHE3 (Na+/H+ exchanger 3) and DRA (Down Regulated in Adenoma, a key Cl-/HCO3 - exchanger) play key roles in mediating intestinal electroneutral NaCl absorption, we sought to evaluate the efficacy of Lactobacillus acidophilus (LA) in counteracting NHE3 and DRA inhibition and ameliorating diarrhea in a model of C rodentium infection and DSS induced colitis. Methods: FVBN mice challenged with C. rodentium (1x109 CFU) with or without administration of live LA (3x109 CFU) were assessed for NHE3 and DRA mRNA and protein expression, mRNA levels of carbonic anhydrase, diarrheal phenotype (assessed by colonic weight/length ratio), myeloperoxidase (MPO) activity and proinflammatory cytokines. For colitis studies, dextran sulfate sodium (DSS in drinking water for 7 days) was used to induce colitis in C57BL/6J mice. Results: LA counteracted C. rodentium-induced inhibition of colonic DRA, NHE3 and carbonic anhydrase I and IV expression, attenuated diarrheal phenotype and MPO activity. Further, LA completely blocked C. rodentium induction of IL-1β, IFN-γ and CXCL1 mRNA and C. rodentium-induced STAT3 phosphorylation. Oral gavage of live LA also showed evident alleviation of inflammatory state by reducing the weight loss, decreased colon length and colon weight in both the models. Also the inflammation as well as the decrease in DRA mRNA and protein levels caused by DSS colitis was blocked by LA. Conclusions: Our data provide mechanistic insights into anti-diarrheal and anti-inflammatory effects of probiotics in models of infectious and chemical injury colitis.

    Background: The gut microbiome may influence brain development and behavior, mainly through the modulation of physiological metabolism and the immune system. Recent studies have determined that the microbiome has direct effects on behavior, and may be dysregulated in neurodevelopmental conditions. Considering that neurodevelopmental conditions, such as autism, have a strong genetic etiology, it is necessary to understand if genes associated with neurodevelopmental disorders, such as Shank3, can influence the gut microbiome, and if probiotics can be a therapeutic tool. Methods/Results: Using 16S high-throughput sequencing, we have determined the gut microbiome community of the Shank3 KO mouse model, and itsrelative controls. In this study, we have identified dysregulation of several genera and species of bacteria in both the gut and colon of Shank3 KO mice, in addition to a sex-dependent dysregulation of the immune system. L. reuteri, a species with decreased relative abundance in the Shank3 KO mice, positively correlated with the expression of GABA receptor subunits in the brain. Treatment of Shank3 KO mice with L. reuteri induced an attenuation of unsocial behavior and a decrease in repetitive behaviors, in males and just decrease in repetitive behaviors in females, without affecting anxiety. L. reuteri treatment also induced an increase in GABA receptor expression in multiple brain regions, and affected serum immune system markers. Perspectives: This study has confirmed that genetic differences associated with autism can induce changes in the microbiota profile. In addition, this study identifies bacterial species that are sensitive to an autism-related mutation, and further suggests a therapeutic potential for probiotic treatment.

    Gut failure is common in ICU patients which characterized by lack of bowel sounds, regurgitation, vomiting, high gastric residual volumes (>500 mL/day), diarrhea, constipation, abdominal distension or GI bleeding. During critical illness, several factors might affect gut microflora that involve changes in stress hormones, gut ischemia, use of antibiotics and immune suppression, gut micrbiota, lack of nutrients and enteral feeding failure. Unfortunately, clinical evaluation of the gut function is difficult therefore gut dysfunction usually goes unrecognized related to poor clinical outcomes and high morbidity and mortality rate. Diet has the strongest effects on gut microbial colonization that could modify the profile of dominant species in human gut and offer different consequences of health. Recent data suggested to preserve or reestablish a healthy gut microbiota during and after critical diseases through targeted interventions such as probiotics, prebiotics, fecal microbial transplants (FMT), and synthetic ‘stool pills’. This review developed to evaluate the efficacy of probiotic/prebiotics in critical ill patients. Probiotics offers many benefits to the host including effective in the treatment or prevention of acute gastroenteritis, GI dysfunctions, antibiotic associated diarrhea (AAD), certain pediatric allergic disorders, necrotizing enterocolitis and inflammatory bowel disease (IBD). Briefly, probiotics use in the ICU remains widespread and no definitive recommendation for the routinely probiotics use in critical ill patients. Further studies are required to define the dose, types and safety of pro- and prebiotics in critically illness. Keywords: Probiotics, prebiotics, critically ill patients, Antibiotic associated diarrhea, Clostridium difficile-associated diarrhea, Ventilator-associated pneumonia.

    Background: Ulcerative colitis (UC) is one of the inflammatory diseases of the gut with frequent bloody diarrhea leads to increased rates of anemia. Evidences indicate the immunomodulation disorders in the response to intestinal microbiota in UC. Although sugarcane molasses, rich in necessary minerals and vitamins could be a good support nutrient but its effect on immune system of UC patients is unknown. To determine how the immune system of UC patients responds to molasses this study planned. Methods: Bifidobacteriumlactis (B. lactis) were cultivated on MRS broth. Peripheral blood mononuclear cells (PBMCs) of 12 UC patients separated by Ficoll-Hypaque centrifugation and co-cultured with UV killed bacteria and/or molasses in RPMI-1640 plus 10% FCS. The FoxP3 gene expression measured by real-time PCR. TGF-β and TNF-α were measured in supernatant of PBMCs by ELISA. Results: Sugarcane molasses and B. lactis significantly augmented TGF-β compared to control (p<0.01 and p<0.001 respectively). The secretion levels of TGF-β by B. lactis plus molasses compared to B. lactis stimulated PBMCs was significantly higher (p<0.05) but the level of TNF-α after 2/4/12 h incubation of PBMCs with B. lactis plus molasses compared to B. lactis alone wasn’t changed (p>0.2). The level of FoxP3 expression after treatment with molasses was increased significantly (p<0.05). Although FoxP3 expression after treatment with the molasses plus B. lactis was increased but it wasn’t significant compared to control. Conclusion: These data show that if sugarcane molasses added to B. lactis, not only would not increase the pro-inflammatory cytokine, TNF-α, but also augments the anti-inflammatory cytokine, TGF-β by PBMCs. Increasing the expression of the FoxP3 could be due to stimulating the activity of the Treglymphocytes. Therefore, sugarcane molasses could be a safe support to compensate the lost nutrients in UC patients.

    Lactobacillus strains are interesting probiotic strains which might have immune modulatory and other beneficial health effects, but each strain can be different in its activity. Here we tested three Lactobacillus strains, L. acidophilusW37, L. brevis W63 and L. casei W56, for their modulatory effects towards small intestinal epithelial cells in vitro and whether the most potent strain L. acidophilus W37 could have immune supportive effects in neonatal piglets. Caco-2 cells differentiated to small intestinal epithelial cells were exposed to L. acidophilus W37, L. brevis W63 and L. casei W56 (107 CFU/mL) for 6 hours. During exposure, trans-epithelial electrical resistance (TEER) was measured to determine the integrity of the confluent epithelialmonolayer. To determine the effect of the Lactobacillus strains on gene expression and related canonical pathways, RNA of Caco-2 cells was harvested after 6 hours incubation hybridized to Affymetrix Human Gene 1.1 ST arrays and Ingenuity Pathway Analysis (IPA) analysis was performed. Additionally, the potential beneficial effect of L. acidophilusW37 on intestinal integrity was studied using Caco-2 cells challenged with Salmonella Typhimurium (STM) DT12. In neonatal piglets, L. acidophilusW37 combined with long chain inulin type fructanFrutafit®TEX! was tested to enhance efficacy of vaccination against Salmonella Typhimurium. Treatments were given daily via oral drenches as of day 2 after birth until sacrifice. Piglets were weaned on day 24 and vaccinated with a single dose of Salmoporc STM®. To analyze the effect on protection againstSTM, animals were challenged with this pathogen before sacrifice. Blood was sampled prior and post vaccination to quantify antibody titers and characterisation of immune cells. In the Caco-2 cell model, L. acidophilus W37 enhanced TEER by 15% (p<0.01) after 6 hours, while the strains L. brevis W63 andL. casei W56 had almost no effect on TEER.Transcriptomic data also showed that L. acidophilusW37 induced much more pronounced effects then the other 2 Lactobacillus strains. Most genes modulated by L. acidophilus W37 were related to intestinal barrier function, inflammation and bacterial stimulation of the epithelial layer.Many genes involved in the regulation of tight junctions were upregulated (e.g. CLDN 3, -4, Rab13)which fits the change in TEER. L. acidophilus W37 seems to impact epithelialimmune interactions via NFkB signaling and the upregulation of markers of follicle-associated epithelium (FAE) indicates thatL. Acidophilus W37 might support epithelial cell differentiation towards tissue with enhanced intestinalimmune sampling capacity. Challenging Caco-2 cells with STM showed a drop in TEER of 24% (p<0.01) compared to medium control. This drop was only 3.9% (p<0.05) in cells pretreated for 17 hours with L. acidophilusW37 compared to medium control, illustrating the beneficial effect of this strain during STM infection.In piglets, the combination of L. acidophilus W37 and Frutafit® TEX! enhanced antibody titters against STM. This positive effect of L. acidophilus W37 on vaccination efficacy is indicative for its immunomodulatory potential. These results demonstrate that L. acidophilus W37can have beneficial effects on intestinal barrier function and aninteresting immune supportive activity. L. acidophilus W37 is therefore potentially useful to support intestinal health to e.g. STM burden in society and immune health for those groups that have a low immune fitness.

    Probiotics – live microbial food supplements – are believed to be beneficial for their consumers by improving intestinal microbial balance, protecting against gastrointestinal disorders, and digesting some food components. Probiotic strains dedicated to some group of organisms should originate from healthy specimens belonging to this group (Sararela et al. 2000). Nowadays, probiotics are omnipresent as functional food and medicaments. Unfortunately, strains isolated from one group of organisms might not turn out to be beneficial for another, thus probiotics dedicated to vertebrates are harmful to or have no beneficial effects on insects (Whitten and Coates 2017, Ptaszyńska et al. 2016, Johanson et al. 2014, Mirjanic et al. 2013). Digestive system of honeybees is mainly inhabited by Lactobacillus kunkeei, L.apinorum, L. mellifer, L. apis, L. mellis and Fructobacillus fructosus (Hroncova et al. 2015). Lactobacilluskunkeei and Fructobacillus fructosus bacteria make up the bulk of the natural, beneficial bacterial flora of honeybees in the summer. Owing to their properties, they occur in any environment with considerable amount of fructose, e.g. pollen, fruit, grape must, etc. Consequently, they also occur in the hive environment. Furthermore, these bacteria are also able to thrive in the honeybee gut, which produces numerous beneficial effects: they help digest and absorb necessary compounds and microelements, protect against mild poisonings with xenobiotics, acidify their environment, which protects the gut from any developments of microorganisms that can be pathogenic for bees, e.g. Paenibacillus larvae that cause foulbrood, or Nosemacerenae fungi that cause nosemosis. They also have immunomodulation effects improving bees’ immunity, strengthening the condition of whole bee families and prolonging bees’ lives. In winter, bees are devoid of contacts with their outdoor environment, also with naturally occurring probiotic bacteria. Hence a whole bee family, especially young winter bees, ought to be in touch with a probiotic.

    Functional ingredients identified for health, nutrition and aging platforms are correlated with positive outcomes including cognitive health. Screening of botanical extracts has identified classes of components with positive outcomes including modifications of the microbiome. Traditional broad-spectrum functional extracts contain several active components. Individually these may also act on multiple targets such that overall positive outcomes integrate a variety of underlying mechanisms. EFSA health-related ingredient marketing claims, now require that defined endpoint efficacy be demonstrated and that a plausible mechanistic link be established. Inherent variability in potency of biological material require measurements of biological efficacy with a strong predictive capacity. Different sage extracts, traditionally used for anti-inflammatory and estrogenic properties, were was tested witha proprietary, high throughput screening tool, Chronoscreen™, which integrates outcomes at a whole organism level using a C.elegans nematode-based technology. It was configured with an array of endpoints indicative of cognitive health benefits. This enabled quantitative differences to be observed and to rank performance against established pharmaceutical actives. In response to sage extract administration, gene expression studies allowed identification of up and down regulated genes and their associated pathways. Comparison with responses to Donepezil(a cognitive health therapeutic), allowed identification of differentially expressed genes and potential test dosages for human clinical trialconfirmation studies. Further mapping to human health conditions suggested potential mechanisms of action consistent with neuro-transmitter modulation, longevity, autophagy and lipid homeostasis pathways and a new understanding of the biology of cognitive health. A human clinical trial was carried out with 4 doses and a placebo given in a single daily dose. Cognitive health end point measurements over a 6-hour period following administration showed a time and dose-dependent significant positive differences with the placebo. Conclusion: This quantitative screening approach showed predictive value for cognitive health performance and suggested potentially unanticipated modes of action.

    Dadih is an Indonesian traditional spontaneous fermented buffalo-milk, produced in West-Sumatra, which is nutritious and has health-benefits. The mechanism of action behind the health-benefits is largely unknown, but several probiotic strains have been isolated from dadih, which may contribute to its health properties. To identify the composition of its microbiota, Two artisanal dadih samples (n=8) were collected from four producers. The raw buffalo-milk used for fermentation was either pasteurized (n=4) or not (n=4), and back-slopping was used as a starter-culture (n=5) or not (n=3). DNA was extracted from each sample in duplicate and the microbiota composition was determined by 16S-rRNA-gene amplicon-sequencing of the V3-V4 region. PCoA analysis showed clear separation of the samples by producer, but no separation due to pasteurization or use of back-slopping. Lactococcus (52%- 83%) predominated in all samples, followed by Klebsiella (5%-26%), and Lactobacillaceae, Bifidobacterium (particularly high (~18%) in the non-pasteurized, back-slopped product from Palupuh), Streptococcus and Leuconostoc. Back-slopping practice correlated significantly with higher abundance of Lactobacillaceae, Pediococcus, species of the order Burkholderiales, and Serratia, but with lower abundance of several other Enterobacteriaceae (including Klebsiella), Streptococcaceae, Staphylococcus and Brachybacterium. Pasteurization was not significantly correlated with presence of certain members of the final microbiota. Taken together, fermentation results differ significantly from producer to producer and back-slopping practice would be advisable. Keywords: Dadih, microbiota, fermentation, back-slopping, pasteurization, buffalo milk.

    Previous research on periodontal structure and function has shown a significant relationship between periodontal tissue and teeth. This study assessed dentist’s beliefs about the relative efficacy of the health of periodontal tissue. A total of 505 patients in general pracrice were asked to respond to a list of 25 obligatory nourishment for a child while going to have the first teeth, for its effectiveness in dealing with patient’s periodontal health especially include chewing hard food. They were also asked to select the three most effective nutrition for periodontal tissue. The imdices of patient perceived importance of the periodontal health were derived and each compared with actual effectiveness as determined from a sample of 250 patients. Although the majority of patient’s rated 18 of 25 nutrition as being very effective, there was no significant association between patient perceived nourishment effectiveness and actual effectiveness. The implications for patient training are discussed.

    TargEDys is a French biotech company aiming to control metabolic disease by modulating the appetite through an intervention on the microbiome. TargEDys’innovative,satiety inducing technology (ProbioSatys),is based on a unique understanding of appetite regulation at the molecular level. Bacteria can send signals of satiety to the brain from the gut by molecularly mimickingsatiety hormones, thus activating natural satiety pathways. This gut-brain axis is the bidirectional communication between the central and enteric nervous systems, linking the emotional and cognitive centres of the brain with peripheral intestinal functions. Gut bacteria are very important in influencing these interactions. The basis of TargEDys’ ProbioSatys technology is a commensal, enterobacteria probiotic strain, Hafnia alvei,that produces the ClpB protein. ClpB is a mimetic of the satiety hormone (α-MSH) that regulates food behaviour at both peripheral and central levels. When released, ClpB directly stimulates the intestinal enteroendocrine L-cells to produce satiety hormones. ClpB also enters the bloodstream to act on satiety regulation in the central nervous system by mimicking α-MSH. The resulting effect is the feeling of satiety or fullness after a meal. The mechanism of Hafnia has been proven preclinicallyin vitro and in vivo and is currently being tested in humans. This probiotic will be launched as a food supplement in April 2019. The preclinical results indicate that after 3 months of treatment customers can expect to safely lose 3-5% of their body weight, see a 5-10% reduction in food intake, improved body composition and activation of lipolysis.

    Ulcerative colitis (UC) a major form of inflammatory bowel disease (IBD) is a cause of significant morbidity worldwide and its incidence and prevalence appear to be increasing with time. Patients with UC frequently experience episodes of bloody diarrhea with or without mucous, abdominal pain, fever and weight loss. UC patients are faced with malnutrition due to numerous pathogenic factors including anorexia, malabsorption, altered metabolism, fluid and electrolyte loss and side effects of medications. That is why the nutrient supplements should be provided to avoid development of nutrient deficiencies. UC is assumed to be a result of a breakdown of tolerance to intestinal environmental antigens such as resident enteric bacteria and altered barrier properties of the mucous and epithelial layers. These alterations can allow luminal antigens to penetrate the intestinal mucosa and elicit an overproduction of pro-inflammatory cytokines and trafficking of effector leukocytes into the intestinal mucosa. This can ultimately lead to uncontrolled and exaggerated intestinal inflammation. This review will present and discuss the immune response of UC patients to different species of probiotics and nutrient supplements.

    It is estimated that the world´s population will cap in the year 2100 at 11 bio people of which 90 % will live in Asia and Africa. The pressure on air, space, water and food supply will be immense. For a company in the food and beverage industry it is evident that business growth will come from Asia and Africa. Today both regions face nutrition related health issues, both a problem for society but also an opportunity for the F&B industry to develop innovate and healthy food solutions and join the public sector in Public Private Partnerships to develop product innovation, new business models and form alliances. Background: Aiming to contribute to Sustainable Development Goals SDG 2 & 3 – improving nutrition and SDG 17 partnerships. Today approximately 2/3 of humanity is affected by malnutrition – the fact that people have no access to food variety. Most devastating effects are during the first 1000 days of a human’s life – from conception to the 2nd birthday. If a human being has no access to a balanced diet during this time the person will either suffer from under-nutrition, stunting and wasting, have impaired brain capacity or will be overweight. In most Asian countries 30 % of children are stunted – too short for their age. Obesity is lowest in Asia, between 10 and 15 % of the population; however, the increase in Asia is the highest with almost 30 % in the last 4 years as a by-product of economic development. Obesity often results in other health problems like diabetes II, colon cancer or heart disease. The cost of obesity to the healthcare systems in Asia are up to 20 % of the total healthcare expenditure. Another health problem in Asia is osteoporosis – it is estimated that one in three women in Asia over 50 will suffer from it – this is mainly due to low milk consumption and no exposure to sunlight. Mission: The public debate tends to be dominated by single solution discussions, which often polarize groups, fan outrage and make constructive collaborations difficult. What is needed is a system change to facilitate healthy food choices for a population in general. We must engage in multi-sectoral dialogues between industry, academia, government and non-governmental organizations. Further each involved party needs to be ready to change, this is essential for development. Multiple, complementary interventions are necessary to show results. Studies are required on how to implement such interventions in different geo-political, social, physical, economic and cultural context. Interventions not as a linear process but rather holistic as a more circular process involving continuous learning, adaption and mainstream transparency.

    The potential role of intestinal microbiota in the etiology of various human diseases has attracted massive attention in the last decade. Experiments in animal models have produced evidence for a causal role of intestinal microbiota in the etiology of obesity and insulin resistance. However, with a few exceptions, such causal relation is lacking for humans and most publications merely report associations between intestinal microbial composition and metabolic disorders such as obesity and type 2 diabetes. Dietary recommendations are generally based on epidemiological evidence of an association between a food, food component or diet with the prevalence of a disease. However for microbiome-targeted dietary recommendations, little or no epidemiological evidence is available. In fact, world-wide no microbiome-related dietary recommendations have been proposed. Nevertheless, diet-induced changes in the microbiota have been shown to be associated with insulin resistance and development of diabetes. However, it is as yet an enigma as to which extend the altered microbiota is causally related to insulin resistance and diabetes or whether these changes in the microbiota are secondary to the development of insulin resistance and diabetes, the latter two induced by non-microbiota dependent pathophysiological mechanisms. Thus, the reciprocal relationship between the gut bacteria and these metabolic disorders remains a matter of debate. In addition, and in particular with respect to fiber, the health benefits of its consumption may be conferred even without the apparent involvement of the microbiome. In particular, e.g. studies into the role of fiber in its capacity to modify the microbiota to confer a health benefit have until now solely relied on measuring the changes in the microbiota at the start and completion of the study. Therefore, changes in the microbiota by itself are not sensitive enough to provide for a causal explanation of the observed metabolic effects. Unless multiple time points are included in the study design, kinetic of changes in the microbiota, combined with simultaneously revealing the kinetics of gene, protein and metabolome expression, applying multiple -omics techniques, microbiome-targeted dietary recommendations will remain elusive.

Paul Joseph Griffith was diagnosed with a rare, autoimmune, skin, disease known as Hidradenitis Suppurativa when he was 23 years old. There is no known clinical cure or effective treatment for the disease. It is also degenerative and believed to affect approximately 1-2% of the American population and possibly globally. Throughout his formative years, the disease progressed and eventually spread across half of his body. He was covered in boils from the waist to his ankles and contemplated ending his own life. He decided in that moment to figure out a solution for himself driven by the research question, “How did our ancestors take care of themselves before modern medicine and technology?” Armed with this driving question, for four years he researched the healing properties of plants, focusing on their microbiology, and created three, signature, products for the skin and scalp. The products assisted in his healing and as a result became popular amongst friends and family members. Before long, the products became popular amongst customers across America with reports of assisted healing with autoimmune diseases such as eczema, psoriasis, dermatitis, folliculitis, cystic acne, chronically dry skin, rashes, and more.

    Probiotic lactic acid bacteria (LAB) can be explored to develop a safe and niche-specific therapeutic regimen against bacterial infections based on their ability to thwart adhesion of pathogens onto intestinal cells. The present investigation reports the potential of native Lactobacillus plantarum strains to inhibit adhesion of model gastrointestinal pathogens, Enterococcus faecalis and Staphylococcus aureus on extracellular matrix (ECM) and cultured intestinal cells (HT-29 cells). A native L. plantarum CRA21 strain rendered significant inhibition of S. aureus MTCC 96 and E. faecalis MTCC 439 adhesion onto ECM molecules, collagen and mucin, with the highest inhibition of S. aureus MTCC 96 adhered on collagen observed in the exclusion mode (83.61%) as compared to competition (62.4%) and displacement (38.58%) mode of adhesion assay. A dual-color flow cytometry (FCM) based adhesion assay indicated that in the exclusion mode, L. plantarum DF9 rendered notable inhibition of pathogen adhesion onto HT-29 cells, with the relative adhered population of E. faecalis MTCC 439 being 3.94% and that of L. plantarum DF9 being 77.56%. FCM along with principal component analysis (PCA) revealed that the native strains of L. plantarum DF9 and L. plantarum CRA38 could significantly affect both the adhesion process parameters kd and em of pathogen, similar to the standard probiotic L. rhamnosus GG. Interestingly, addition of the bacteriocin plantaricin A obtained from L. plantarum could reduce the viability of ECM-adhered pathogens. Host cell adhesion assays indicated that addition of plantaricin A on LAB and pathogen adhered onto HT-29 cells led to a prominent reduction in the adhered E. faecalis MTCC 439 cells (17.4%) as compared to L. plantarum DF9 (70.5%), which highlighted the benefit of using LAB bacteriocin for selective eradication of pathogen and minimal collateral damage. It is envisaged that the native probiotic L. plantarum strains can be used in conjunction with LAB bacteriocins as niche-specific anti-adhesion therapeutic agents against gastrointestinal pathogens.

Recently,she is focusing her interest in characterization of unculturable bacterial diversity in some endemic plants. This work might help conserve plants which are on verge of extinction or are in rare or endangerd category. Dr. Pandey also work on Methylobacteriaum which play significant role mitigating methane levels emanating from deep water rice cultivation and coal bed mines. In her early years at DYPBBI she has characterized many PGPR strains including nonfluorescent Pseudomonas stutzeri an endophyte inhabiting Sunflower (Halianthusannus) roots. Part of Dr. Pandey’s motivation for moving to characterization of Antimicrobial Peptide (AMPs) was because she got interested in addressing the issue of crop spoilage and heavy toll of crops due to pathogenic infestations. Also, already having realized the detrimental effects of use of chemical pesticides & chemical fertilizers in environment & aquatic habitat. Use of these deleterious chemicals is also carcinogenic and associated with other health hazards. Not only its use but also its production causes global warming and &unsustainable burden of the fiscal system. Biodiversity has always been her preferred areaof study.With 3,80,000 plants reported so far, they are promising candidates for exploring endophytic microbial diversity. As endophytes are poorly investigated group of microorganisms that represents an abundant and dependable source of bioactive and chemically novel compounds with potential for exploitation in a wide variety of medical, agricultural & industrial areas.

    Bioactive peptides or antimicrobial peptides (AMPs) characterization has received great attention in the recent past due to their application as therapeutic agents and also as food preservatives without any toxic effects on host. At present, food preservation is a serious concern for almost all countries across the worldA serious challenge to antimicrobial therapies is the rapid increase in antibiotic resistant infections. Therefore, an urgent need to develop other biocontrol agents is the need of the hour. Staphylococcus aureus is a major bacterial pathogen that causes clinical infection and foodborne illnesses. Food preservatives are widely used to reduce the risk of food poisoning. With growing consumer demand for natural preservatives to replace chemical compounds, new antimicrobial products of various origins are being developed. Endophytes from enormous number of diverse plants and environmental conditions are potential source for isolation of bioactive compounds.While a wide range of biologically active compounds have been isolated from endophytic organisms, they still remain a relatively untapped source of novel natural product. Endophytic microbes seem to fit perfectly into this natural warehouse, only a small part of which we have been able to tap in so far. In this study, a Bacillus strain showed antimicrobial activity characterized by Kirby Bauer method of well/disc diffusion and soft agar overlay assay. The bacterial supernatant showed zone of inhibition after 16hr of incubation at 370C against Staphylococcus. The culture supernatant was precipitated with ammoniumsulphate (80% saturation) and column chromatography was performed with Sephadex G-50 followed by DEAE column purification. The purified fraction was used for characterization by Sodium Dodecyl– Polyacrylamide Gel electrophoresis (SDS –PAGE).

    Background: Bacteriocins from lactic acid bacteria (LAB) have been excellent biotherapeutic agents to be used against pathogenic bacteria. However, the antibacterial activities of bacteriocins from indigenous LAB have not been validated scientifically from our part of the globe. The current study determines the antibacterial properties and characterizes bacteriocin isolated from local Lactobacillus strains. Methods: Five commercial curd samples were processed microbiologically, using MRS media, in order to isolate LAB. The LAB was identified following conventionaland molecular methods, and the probiotic features were validated. Antagonistic properties of the isolated LAB were determined against the indicator pathogenic bacteria. Bacteriocin isolated from such probiotic strains were characterized through enzyme treatment, SDS-PAGE analysis and antibacterial property. Result: The LAB isolates were identified as Lactobacillus Spp. and the isolates showed probiotic features, with tolerance to variable temperature (15°C and 42°C) and acid (pH 2-4), bile salt (0.125%, 0.25% and 0.50 %) and NaCl (2%, 4% and 6.5%). The LAB were γ-hemolytic and did not cause gelatin hydrolysis and mostly were sensitive to the antibiotics tested. Antagonistic activity test revelsa zone diameter of inhibition (ZDI) of 16-46 mm and 7-26 mm in agar-overlay and agar-well techniques, respectively, against the gram positive and gram negative indicator bacterial pathogens. The isolated bacteriocins from probiotic LAB were of 11-14 kDa. The bacteriocin showed antibacterial activity displaying ZDIs 15-30 mm and minimum inhibitory concentration (MICs) 7.12 – 483.12 µg/ml. Conclusion: The lactobacilli were excellent probiotics, and the bacteriocin from the LAB had a broad spectrum of antibacterial activity. Thus, the indigenous Lactobacillus strains from local niches and the bacteriocin isolated from them might be used as biotherapeutic agents against bacterial infection.

    Probiotic bacteria provide significant health benefits and can be incorporated into foods in order to develop functional products with particular commercial interest. According to IDF, the minimum concentration of probiotic bacteria in the final product should be 107 cfu/g. However, the survival of probiotic bacteria and the maintenance of their functionality during food processing and preservation, and through their passage from the gastrointestinal tract must be ensured. Encapsulation technology ensures the viability and integrity of the cells. Various encapsulation methods have been reported in the literature. In this study, the encapsulation of Bifidobacterium animalis subsp. Lactiswas achieved through freeze-drying and extrusionusing various encapsulating agents.The encapsulated by freeze-drying bacteria were incorporated in milk (1011cfu/L), while the encapsulated by extrusion bacteria were used (7,5*1010cfu/L) along with the conventional starter culture. In both cases, the inoculated milk was fermented into yogurt at 45oC. The time required to reach pH=4.5 was recorded as fermentation time. After fermentation was completed the physicochemical (viscosity, texture) and microbiological characteristics of the samples wereevaluated. In the case of encapsulation by freeze-drying, cyclodextrin provided bacterial load values of 9*105cfu/g and exhibited superior physicochemical characteristics amongst the encapsulating agents studied. In the case of encapsulation by extrusion, the highest bacterial load values in the final yogurt product were achieved by the mixtures of alginate-inulin and alginate-maltodextrin (1.54*106cfu/g and 9.6*105cfu/g respectively) as encapsulating agents. The alginate-inulin mixture also provided samples with satisfactory physicochemical characteristics as well.

    Background: Indigenous lactic acid bacteria are well known probiotics having antibacterialactivity against potentially pathogenic bacteria. This study aims to characterize the curd lactobacilli for their probiotic potentiality and antagonistic activity against clinical bacteria. Methods: Four curd samples were processed microbiologically for the isolation of lactic acid bacteria (LAB). The LAB strains obtained were identified by conventional methods: cultural aspect, gram-staining, biochemical and sugar fermentation tests. The probiotic properties were justified with tolerance to low-pH, bile salt and sodium chloride, and the antagonistic activity of the lactobacilli against human pathogenic bacteria (Escherichia coli, Proteus vulgaris, Acinetobacterbaumannii and Salmonella entericaserovarTyphi) was assessed. Hemolytic activity and antibiotic susceptibility were determined for the lactobacilli isolates, and the cumulative probiotic potential (CPP) values were recorded. Result: Four lactobacilli isolates, L. animalisLMEM6, L. plantarumLMEM7, L. acidophilusLMEM8 and L. rhamnosusLMEM9, procured from the curd samples, survived in low-pH and high bile salt conditions, and showed growth inhibitory activity against the indicator bacteria by agar-well (zone diameter of inhibition; ZDIs: 13.67 ±0.58–29.50 ±2.10 mm) and agar overlay (ZDIs: 11.33 ±0.58–35.67 ±2.52 mm) methods; the average growth inhibitory activity of lactobacilli ranged 233.34 ±45.54–280.56 ±83.67 AU/mL, against the test bacterial pathogens. All the lactobacilli were non-hemolytic and sensitive to most of the test antibiotics. The CPP values of the isolated LAB were recorded as 80–100%. Conclusion: The curd lactobacilli procured might be used as the valid candidates of probiotics, and bio-therapeutics against bacterial infection to humans. Keywords: lactobacilli; probiotics; antagonistic activity; indicator bacterial pathogens; antibioticsusceptibility; γ-hemolytic activity; cumulative probiotic potential
