Project description:The alkaliphilic halotolerant bacterium Bacillus sp. N16-5 often faces salt stress in its natural habitats. One-color microarrays was used to investigate transcriptome expression profiles of Bacillus sp. N16-5 adaptation reactions to prolonged grown at different salinities (0%, 2%, 8% and 15% NaCl) and the initial reaction to suddenly alter salinity from 0% to 8% NaCl.
Project description:Investigation of whole genome gene expression level in motile strain of Sphingomonas. sp A1 All flagellar genes in motile strain of Sphingomonas. sp A1 are highly transcribed.
Project description:The influence of the presence of glucose in the Y1 growth medium of Bacillus cereus strain ATCC 14579 was studied by transcriptional analysis. Furthermore, the role of CcpA in glucose induction or repression of gene expression was assessed by use of a ccpA deletion strain. In total, 300 genes were glucose repressed and 173 genes glucose activated. For 212 genes the glucose repression was clearly CcpA dependent, whereas for 116 genes CcpA dependent glucose induction was observed. Functional analysis of the glucose regulated genes showed these genes mainly to be involve in energy production and conversion and in metabolism. Furthermore, genes that were glucose repressed were shown to be involved in cell motility.
