Screening of exopolysaccharide-producing Lactobacillus and Bifidobacterium strains isolated from the human intestinal microbiota.
نویسندگان
چکیده
Using phenotypic approaches, we have detected that 17% of human intestinal Lactobacillus and Bifidobacterium strains could be exopolysaccharide (EPS) producers. However, PCR techniques showed that only 7% harbored genes related to the synthesis of heteropolysaccharides. This is the first work to screen the human intestinal ecosystem for the detection of EPS-producing strains.

Production of exopolysaccharides by Lactobacillus and Bifidobacterium strains of human origin, and metabolic activity of the producing bacteria in milk.
This work reports on the physicochemical characterization of 21 exopolysaccharides (EPS) produced by Lactobacillus and Bifidobacterium strains isolated from human intestinal microbiota, as well as the growth and metabolic activity of the EPS-producing strains in milk. The strains belong to the species Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus vaginalis...
متن کاملProbiotic Bifidobacterium breve Induces IL-10-Producing Tr1 Cells in the Colon
Specific intestinal microbiota has been shown to induce Foxp3(+) regulatory T cell development. However, it remains unclear how development of another regulatory T cell subset, Tr1 cells, is regulated in the intestine. Here, we analyzed the role of two probiotic strains of intestinal bacteria, Lactobacillus casei and Bifidobacterium breve in T cell development in the intestine. B. breve, but no...
متن کاملComparison of the Lactobacillus and Bifidobacterium Population in Fecal Microbiome of Celiac Disease Patients on Gluten-Free Diet With Healthy Subjects
Aims Celiac disease (CD) is a chronic autoimmune disease triggered by gluten and other environmental factors, such as intestinal microbiota in genetically predisposed persons. This study aimed to evaluate the composition of the target gut microbiota population in patients with CD and to compare it with healthy individuals. Methods & Materials In this case-control study, Bifidobacterium and Lac...
متن کاملDetermination of Bacteriocin Genes and Antibacterial Activity of Lactobacillus Strains Isolated From Fecal Healthy Individuals
Lactobacillus species play an important role in gastrointestinal (GI) tract function, intestinal microbiota balance, and the immune system activity by exerting a strong activity against many intestinal pathogens. The aim of this study was to isolate Lactobacillus species from fecal samples, investigate their antimicrobial properties, and characterixe their bacteriocins encoding genes. 48 fecal ...
متن کاملThe Composition of Human Milk and Infant Faecal Microbiota Over the First Three Months of Life: A Pilot Study
Human milk contains a diverse array of bioactives and is also a source of bacteria for the developing infant gut. The aim of this study was to characterize the bacterial communities in human milk and infant faeces over the first 3 months of life, in 10 mother-infant pairs. The presence of viable Bifidobacterium and Lactobacillus in human milk was also evaluated. MiSeq sequencing revealed a larg...
