(Submitter supplied) Lactobacillus acidophilus NCFM is an industrially important strain used extensively as a probiotic culture. Tolerance of the presence of bile is an attribute important to microbial survival in the intestinal tract. A whole-genome microarray was employed to examine the effects of bile on the global transcriptional profile of this strain, with the intention of elucidating genes contributing to bile tolerance. more...

(Submitter supplied) Lactic acid bacteria have been used as starter strains in the production of fermented dairy products for centuries. Lactobacillus acidophilus is a widely recognized probiotic bacteria commonly added to yogurt and used in dietary supplements. In this study, a whole genome microarray was employed to monitor gene expression of L. acidophilus cells propagated in 11% skim milk (SM) during early, mid and late logarithmic phase, and stationary phase. more...

(Submitter supplied) A shotgun microarray-based approach was used to identify candidate genes encoding the FOS utilization pathway in L. paracasei 1195. Differential expression profiles between cells grown on FOS and glucose provided a basis for identifying genes specifically induced by FOS. In addition, transcriptional analysis of cells grown on FOS or FOS + glucose allowed us to investigate the effect of catabolite repression on the expression of the FOS-induced genes. more...
