Project description:In order to understand LBG derived galacto-manno-oligosaccharides utilization by a probiotic bacterium, Lactobacillus plantarum WCFS1, we have grown Lactobacillus plantarum WCFS1 (in duplicates) till mid log phase (OD600nm ~0.5, 10 h) in carbon free MRS (de Man, Rogosa Sharpe ) media containing either galacto-manno-oligosaccharides, mannose, glucose or galactose (1% w/v) as the sole carbon source.
Project description:Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with oleuropein. Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. The transcriptional profile shows that Lactobacillus plantarum WCFS1 adapts its metabolic capacity to acquire certain carbohydrates and repress the expression of genes involved in fatty acid biosyntheis. The transcriptomic datasets also revealed the downregulation of genes related to the biosynthesis of capsular polysaccharides and genes coding for ABC-type transporters. In addition, induction of oligopeptide permeases is also part of the response of Lactobacillus plantarum WCFS1 to oleuropein.
Project description:Transcriptome profiles of control Lactobacillus plantarum WCFS1 cells were compared with 8% ethanol adapted cells and with 10 min or 30 min 8% ethanol shocked cells.
Project description:Lactobacillus plantarum was grown anaerobically on 4 different sugars (Mannose Lactose Fructose and Sucrose) to OD600 = 1.0. Samples were compared with a similar grown culture on glucose. An independnet biological duplicate of tht experimnet was performed (samples 1 and 2). L. plantarum WCFS1 grown in glucose, mannose, fructose, and sucrose
Project description:The study evaluates the effect of Lactiplantibacillus plantarum IMC 510® supplementation on anthropometric and biochemical parameters, GM composition and gastrointestinal and general symptoms of overweight/obese subjects.
