The Effects of Origanum Vulgare on The Growth of Lactobacillus Casei and Lactobacillus Paracasei in Probiotic Milk
The objective of this study ware to investigate the effects of different doses of Origanum vulgare on the growth of Lactobacillus casei and Lactobacillus paracasei (separated from Iranian dairy products) in milk produced at one step. The product was then examined in terms of pH, acidity and microbe counting during incubator setting period. In the milk samples with Lactobacillus casei, the contr...
متن کاملMucin degradation in human colon ecosystems. Evidence for the existence and role of bacterial subpopulations producing glycosidases as extracellular enzymes.
Recent work indicates that subpopulations of human fecal bacteria, averaging approximately 1% of the total viable fecal flora, degrade the oligosaccharide side chains of hog gastric mucin, which structurally resembles human epithelial mucins. Here we report studies to determine whether degradation of mucin oligosaccharides is related to glycosidase production by bacteria growing in anaerobic fe...
متن کاملCatabolite repression in Lactobacillus casei ATCC 393 is mediated by CcpA.
The chromosomal ccpA gene from Lactobacillus casei ATCC 393 has been cloned and sequenced. It encodes the CcpA protein, a central catabolite regulator belonging to the LacI-GalR family of bacterial repressors, and shows 54% identity with CcpA proteins from Bacillus subtilis and Bacillus megaterium. The L. casei ccpA gene was able to complement a B. subtilis ccpA mutant. An L. casei ccpA mutant ...

متن کاملFunctional 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 ...
