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: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.
