Project description:Lactobacillus casei is remarkably adaptive to diverse habitats. To understand the evolution and adaptation of Lb. casei strains isolated from different environments, the gene content of 22 Lb. casei strains isolated from various habitats (cheeses, n=8; plant materials, n=8; and human sources, n=6) were examined by comparative genome hybridization with an Lb. casei ATCC 334-based microarray.

To understand the evolution and adaptation of Lb. casei strains isolated from different environments, the gene content of 22 Lb. casei strains isolated from various habitats (cheeses, n=8; plant materials, n=8; and human sources, n=6) were examined by comparative genome hybridization with an Lb. casei ATCC 334-based microarray. Comparative genome hybridization was performed against an Affymetrix custom microarray designed to include 2,661 (97%) chromosomal and 17 (85%) plasmid CDSs predicted to occur in Lb. casei ATCC 334, as well as all predicted CDSs in the draft Lb. helveticus CNRZ 32 genome. CDSs that were not included in the microarray design were all transposase-encoding genes.

Project description:In the present study we characterized the sRNA profile of Lactobacillus casei BL23 using conventional and mDOT-seq approaches. In total 307 potential sRNAs were identified, 28 of which were validated by Northern hybridization. As a major portion of predicted sRNAs were shown to be conserved among the related species of Lactobacillus casei group (LCG), the results obtained in this study could serve as a valuable resource for achieving a better understanding of LCG physiology or even improving their applications in industry and medicine.

Project description:The response to bile of Lactobacillus casei BL23 was investigated. Lactobacillus casei BL23 was grown in MRS medium at 37C without shaking until O.D. 595 nm. reached 0.5. The cultures were then two fold diluted with prewarmed MRS medium (control) or MRS supplemented with 0.2% bovine bile (treatment) and incubation continued for 45 min. Cells were then harvested and total RNA purified.

Project description:Lactobacillus casei Zhang is a probiotic bacterium isolated from koumiss in Inner Mongolia of China. Gene expression dynamics of L. casei Zhang during growth in soymilk was investigated in attempt to reveal the mechanisms involved in growth stimulation for growing probiotics in. Comparison of different transcripts next to each other revealed 162 and 63 significantly induced genes in late logarithmic phase and stationary phase, of which the expression was at least 3 fold up-regulated and down-regulated, respectively. Approximately, 38.4% of the up-regulated genes were associated with amino acid transport and metabolism notably for histidine and lysine biosynthesis, followed by genes/gene clusters involved in carbohydrate transport and metabolism, lipid transport and metabolism, and inorganic ion transport and metabolism. The analysis results suggest that the stimulatory effect of soymilk-based ecosystem on the L. casei Zhang growth is more complex than amino acids or oligopeptides supply.

The analysis results suggest that the stimulatory effect of soymilk-based ecosystem on the L. casei Zhang growth is more complex than amino acids or oligopeptides supply. To study gene expression dynamics of L. casei Zhang during growth in soymilk, a whole genome microarray was used to screen for differentially expressed genes when grown to lag phase, late logarithmic phase, and stationary phase.

Project description:Lactobacillus casei Zhang is a probiotic bacterium isolated from koumiss in Inner Mongolia of China that has been commercially used as a starter in the manufacture of dairy products. To study the gene expression profiles of L. casei Zhang during growth in milk, a whole-genome microarray was used. Compared to L. casei Zhang grown to late logarithmic phase in milk, 61 genes were significantly up-regulated (>5 fold) in stationary phase, whereas 26 genes were down-regulated. Collectively, these data showed that the majority of the identified genes was involved in carbohydrate metabolism and energy production, followed by genes involved in nucleotide metabolism, inorganic ion transport, amino acid transport and metabolism, chaperone, etc. This study demonstrates the fundamental effects of cultural conditions on the transcriptome of L. casei Zhang. Moreover, it improves the understanding of the growth and survival mechanism of the bacterium during the late stage of milk fermentation.

Project description:DNA methylation is an important epigenetic modification. DNA methylation phenomenon exists widely in bacteria, plants and animals and is involved in a variety of biological processes.The wild Lactobacillus casei Zhang and its mutant Lactobacillus casei Zhang Δpglx were used as the research subjects.Proteomics was used to explore the effects of DNA methylation on various aspects of Lactobacillus casei.
