Complete Genome Sequence of the Probiotic Lactobacillus casei Strain BL23
TLDR
The entire genome of Lactobacillus casei BL23, a strain with probiotic properties, has been sequenced and the industrially used probiotic strain Shirota YIT 9029 (Yakult) seem to be very similar.
Microbial ecology and host-microbiota interactions during early life stages
TLDR
It is concluded that the exposure to the adequate microbes early in gestation and neonatal period seems to have a relevant role in health and probiotic interventions aiming to reduce the risk of immune-mediated diseases may appear effective during early life.
Enzyme I and HPr from Lactobacillus casei: their role in sugar transport, carbon catabolite repression and inducer exclusion
We have cloned and sequenced the Lactobacillus casei ptsH and ptsI genes, which encode enzyme I and HPr, respectively, the general components of the phosphoenolpyruvate–carbohydrate
Functional Analysis of the p40 and p75 Proteins from Lactobacillus casei BL23
TLDR
Results indicate that extracellular proteins belonging to the machinery of cell-wall metabolism in the closely related L. casei/paracasei-L.
Identification of a Gene Cluster Enabling Lactobacillus casei BL23 To Utilize myo-Inositol
TLDR
Genome analysis of Lactobacillus casei BL23 revealed that, compared to L. casei ATCC 334, it carries a 12.8-kb DNA insertion containing genes involved in the catabolism of the cyclic polyol myo-inositol (MI), which is the first example of an operon for MI utilization in lactic acid bacteria.
Catabolite repression in Lactobacillus casei ATCC 393 is mediated by CcpA
TLDR
The role of CcpA as a common regulatory element mediating catabolite repression in low-GC-content gram-positive bacteria is supported, and the gene was able to complement a B. subtilis ccpA mutant.
Perspectives of engineering lactic acid bacteria for biotechnological polyol production
TLDR
The polyol production by LAB is reviewed, focusing on metabolic engineering strategies aimed to redirect sugar fermentation pathways towards the synthesis of biotechnologically important sugar alcohols such as sorbitol, mannitol, and xylitol.
Horizontal gene transfer in the molecular evolution of mannose PTS transporters.
TLDR
The functional role and distribution of mannose-class PTS transporters suggest that their expansion may have played a significant role in the establishment of symbiotic relationships between animals and some bacteria.
Structural and Functional Analysis of the Gene Cluster Encoding the Enzymes of the Arginine Deiminase Pathway ofLactobacillus sake
TLDR
Transcriptional studies indicated that arcA gene is subject to catabolite repression, and under the conditions used, several transcripts could be detected, suggesting the existence of different initiation sites or processing of a larger mRNA.
