The phosphate-starvation response of Bacillus licheniformis

Authors


Abstract

The phosphate-starvation stimulon of Bacillus licheniformis was analyzed at the transcriptional and translational level. The comparison of the transcriptome and the proteome demonstrated that this specific starvation response of B. licheniformis is partially similar to that of B. subtilis. However, it is also shown that B. licheniformis has evolved its own strategies to cope with this nutrient limitation. By means of the secretome analysis the phytase was identified as the most abundant protein under phosphate-starvation conditions. Data of this study indicate that, unlike in B. subtilis, phosphate starvation in B. licheniformis does not induce the SigmaB-dependent general stress response.
