Transcriptome profiles of a riboflavin-producing B.subtilis RH33 and wild type B.subtilis 168

Project description:The transcriptome profiles of a riboflavin-producing recombinant Bacillus subtilis RH33 and wild type Bacillus subtilis 168 were compared using DNA microarrays to identify the target genes for further enhancing riboflavin production. Transcriptome profiles of a riboflavin-producing B. subtilis RH33 were compared with those of the wild-type B. subtilis 168 as a control strain during exponentially growing period on LBG medium. These conditions corresponded to the state of high riboflavin production, which was growth related. For each comparison, two independent cultivations on LB medium with 1% glucose were performed, and exponentially growing cells (OD600 3â6) were harvested. The synthesis of cDNA and biotin-labeled cRNA were carried out exactly as described in the Affymetrix GeneChip Expression Analysis Technical Manual (2000).

Expression analysis of sporulating Bacillus subtilis strain 168 deleted for prpE gene

Project description:Investigation of whole genome gene expression level changes in sporulating Bacillus subtilis 168 delta-prpE mutant, compared to the wild-type strain. The mutation engineered into this strain results in impaired germination of spores. A six chip study using total RNA extracted from three separate wild-type cultures of sporulating Bacillus subtilis 168 and three separate cultures of sporulating mutant strain, Bacillus subtilis 168 delta-prpE, in which prpE (yjbP BSU11630) gene coding for a protein phosphatase is deleted entirely. Each chip consists of four fields able to measure the expression level of 4,104 genes from Bacillus subtilis subsp. subtilis strain 168 NC_000964 with eight 60-mer probe pairs (PM/MM) per gene, with two-fold technical redundancy.

Transcriptomic analysis of VBNC cells of osmostressed Bacillus subtilis 168

Project description:Characterization of the putative genetic determinants of the VBNC state in a known spore-forming Gram-positive organism Bacillus subtilis 168. The VBNC state was induced under osmotic stress and aminoglycoside treatment. The transcriptome landscape of VBNC cells was compared to the viable, antibiotic sensitive B. subtilis cells and to the viable cells with no antibiotic treatment.
