Identification of prebiotic fructooligosaccharide metabolism in Lactobacillus plantarum WCFS1 through microarrays.
Short-chain fructooligosaccharides (scFOS) and other prebiotics are used to selectively stimulate the growth and activity of lactobacilli and bifidobacteria in the colon. However, there is little information on the mechanisms whereby prebiotics exert their specific effects upon such microorganisms. To study the genomic basis of scFOS metabolism in Lactobacillus plantarum WCFS1, two-color microa...
متن کاملComplete genome sequence of Lactobacillus plantarum WCFS1.
The 3,308,274-bp sequence of the chromosome of Lactobacillus plantarum strain WCFS1, a single colony isolate of strain NCIMB8826 that was originally isolated from human saliva, has been determined, and contains 3,052 predicted protein-encoding genes. Putative biological functions could be assigned to 2,120 (70%) of the predicted proteins. Consistent with the classification of L. plantarum as a ...
متن کاملLactobacillus plantarum WCFS1 electron transport chains.
Lactobacillus plantarum WCFS1 requires both heme and menaquinone to induce respiration-like behavior under aerobic conditions. The addition of these compounds enhanced both biomass production, without progressive acidification, and the oxygen consumption rate. When both heme and menaquinone were present, L. plantarum WCFS1 was also able to reduce nitrate. The ability to reduce nitrate was sever...
متن کاملIdentification of Lactobacillus plantarum in Breast Milk
Backgrounds : The role of potentially probiotic lactic acid bacteria of human milk in the early colonization and protection of infant against infections is the subject of increasing researches. Colonization with Lactobacillus plantarum in early infancy is suggested to be important for health in later life. However, we presently investigated the strain of Lactobacil...
متن کاملPhysiological responses to folate overproduction in Lactobacillus plantarum WCFS1
BACKGROUND Using a functional genomics approach we addressed the impact of folate overproduction on metabolite formation and gene expression in Lactobacillus plantarum WCFS1. We focused specifically on the mechanism that reduces growth rates in folate-overproducing cells. RESULTS Metabolite formation and gene expression were determined in a folate-overproducing- and wild-type strain. Differen...
