Project description:We applied total RNA sequencing of Lactobacillus fermentum strain GR1008 and GR1009 and compare the differentially expressed genes. This study aimed to find out the underlying mechanims for the differential morphology of the two strains.

Synbiotic impact of tagatose on viability of Lactobacillus rhamnosus strain GG mediated by the phosphotransferase system (PTS)

Project description:The presence of tagatose in Lactobacillus rhamnosus strain GG caused induction of a large number of genes associated with carbohydrate metabolism including the phosphotransferase system. In addition, these results indicate the tagatose enhanced the growth of Lactobacillus casei 01 and Lactobacillus rhamnosus strain GG and their probiotic activities by activating tagatose-associated PTS networks. Two-condition experiment, Lactobacillus rhamnosus GG with glucose vs. Lactobacillus rhamnosus GG with tagatose. For preparing the total RNA, Lactobacillus rhamnosus GG cells were grown at 37M-BM-0C in prebiotic minimum medium supplemented with 2% glucose or tagatose for 24 h.

Comparison of the response to bile of Lactobacillus casei BL23 and its derivative strain TC01

Project description: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. Lactobacillus casei BL23 and TC01 strains were 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.
