Pentitol metabolism in Lactobacillus casei.

Utilization of D-ribitol by Lactobacillus casei BL23 requires a mannose-type phosphotransferase system and three catabolic enzymes.

Lactobacillus casei strains 64H and BL23, but not ATCC 334, are able to ferment D-ribitol (also called D-adonitol). However, a BL23-derived ptsI mutant lacking enzyme I of the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) was not able to utilize this pentitol, suggesting that strain BL23 transports and phosphorylates D-ribitol via a PTS. We identified an 11-kb region in the g...

Effects of Lactobacillus casei probiotics on growth performance, blood parameters and intestinal microbial flora in juvenile goldfish (Carassius auratus)

Lactobacillus casei probiotic is one of the probiotics used in aquaculture industry. The aim of this study was to evaluate the effect of Lactobacillus casei probiotic on the growth performance, blood parameters, and intestinal microbial flora in goldfish (Carassius auratus) for 60 days. In this study, 180 fish with an average weight of 10.11± 0.16 g were randomly distributed into two treatments...

Functional analysis of the p40 and p75 proteins from Lactobacillus casei BL23.

The genomes of Lactobacillus casei/paracasei and Lactobacillus rhamnosus strains carry two genes encoding homologues of p40 and p75 from L. rhamnosus GG, two secreted proteins which display anti-apoptotic and cell protective effects on human intestinal epithelial cells. p40 and p75 carry cysteine, histidine-dependent aminohydrolase/peptidase (CHAP) and NLPC/P60 domains, respectively, which are ...
