Project description:Set the bacteria solution without polysaccharides from Polygonatum kingianum(PS) as the control group (CON group), and the bacteria solution with PS added as the administration group (PS group), the target strain treated with and without PS (20 μg/mL) was used for proteomic analysis.
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.
