Project description:Transcriptome comparison of Bacillus subtilis Natto under sliding permissive (0.7% agar) and restrictive (1.5% agar or spo0A mutant strain) conditions.
Project description:Transcriptome comparison of Bacillus subtilis Natto under sliding permissive (0.7% agar) and restrictive (1.5% agar or spo0A mutant strain) conditions. B subtilis Natto wild type cells were grown on the top of LB solid medium with 1.5% and 0.7% agar concentration (samples 1-4). B subtilis Natto wild type and spo0A derivative were grown on top of LB solid medium with 0.7% agar concentration (Sample 5-7). In first experiment, 4 biological replicates were used, while in the second experiment 3 biological replicates included. Dye swaps are included in both experiments.
Project description:We found that biofilm formation ability of E. faecalis was impacted by culture supernatant of probiotic B. subtilis natto. To further understand how E. faecalis responded to B. subtilis natto supernatant, we searched for differentially expressed genes between E. faecalis treated with or without B. subtilis natto supernatant using RNA-seq analysis.
Project description:In the present study, we investigated the effect of Bacillus subtilis var. natto on lifespan using Caenorhabditis elegans as a model animal. The lifespan of the adult C. elegans fed Bacillus subtilis var. natto MI-OMU01 strain was significantly longer than that of animals fed OP50 (control). Transcriptional profiling comparing MI-OMU01- and control-fed animals suggested that genes related to “innate immune system” were upregulated by MI-OMU01.
Project description:Identification of the specific WalR (YycF) binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the WalRK regulon in Bacillus subtilis and its role in cell wall metabolism, as well as implying a role in several other cellular processes.
