(Submitter supplied) The response to bile of Lactobacillus casei BL23 and its derivative strain TC01 was investigated. TC01 strain carries a complete deletion of gene LCABL_02080 which encodes a two component signal transduction response regulator.

(Submitter supplied) Bifidobacterium longum is one of the natural inhabitants in human gastrointestinal tract. In order to colonize and exert particular functions in the gut, it has to be tolerant to the physiological concentrations of bile salts. In this work, we used RNA-Seq transcriptomics based on the Next-Generation Sequencing to investigate the global response to bile in B. longum BBMN68, a potential probiotic strain isolated from a healthy centenarian. more...

(Submitter supplied) Transcriptional profiling of Lactobacillus reuteri ATCC 55730 mid-log cultures before vs after exposure to 0.5% bovine bile (oxgall). Two sets of array experiments were performed. One set compared the expression profiles of L. reuteri ATCC 55730 cells before bile exposure vs cells that had been exposed to 0.5% bile for 15 minutes (bile shock). The other set compared the expression profiles of L. reuteri ATCC 55730 cells before bile exposure vs cells that had begun growing again in the presence of 0.5% bile (bile adaptation). more...

(Submitter supplied) This study investigated features of the acid tolerance response (ATR) in Lactobacillus casei ATCC 334. To optimize ATR induction, cells were acid adapted for 10 or 20 min at different pH values (range, 3.0 to 5.0) and then acid challenged at pH 2.0. Adaptation over a broad range of pHs improved acid tolerance, but the highest survival was noted in cells acid adapted for 10 or 20 min at pH 4.5. Analysis of cytoplasmic membrane fatty acids (CMFAs) in acid-adapted cells showed that they had significantly (P < 0.05) higher total percentages of saturated and cyclopropane fatty acids than did control cells. more...

(Submitter supplied) The DNA is printed, spotted, or actually synthesized directly onto the support. The whole process is based on hybridization probing, a technique that uses fluorescently labeled nucleic acid molecules as "mobile probes" to identify complementary molecules, sequences that are able to base-pair with one another.
