(Submitter supplied) Background: The Bacillus cereus Sigma B (SigB) dependent general stress response is activated via the two-component RsbKY system, which involves a phosphate transfer from RsbK to RsbY. It has been hypothesized that the Hpr-like phosphocarrier protein (Bc1009) encoded by bc1009 in the SigB gene cluster may play a role in this transfer, thereby acting as a regulator of SigB activation. Alternatively, Bc1009 may be involved in the activation of a subset of SigB regulon members. more...

(Submitter supplied) Heat-treated spores show delayed and slower germination and outgrowth compared to untreated spores presumably due to spore damage repair. This study was performed to identify genes possibly involved in spore damage repair in B. cereus. In this study we compared the transcriptomic profiles of untreated and heat-treated spores during germination and outgrowth in BHI at 30C.

(Submitter supplied) Planktonic and biofilm cells of Bacillus cereus ATCC 14579 and ATCC 10987 were studied using microscopy and transcriptome analysis. By microscopy, clear differences could be observed between biofilm and planktonic cells as well as between the two strains. By using hierarchical clustering of the transcriptome data, little difference was observed between the biofilm cells of B. cereus ATCC 14579 and ATCC 10987. more...

(Submitter supplied) 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. more...

(Submitter supplied) Members of the Bacillus cereus group can adapt to a wide range of environmental challenges. In bacteria, these challenges are often translated into a transcriptional response via the cognate response regulators (RRs) of specialized two-component systems (TCSs). We have previously developed a phylogenetic footprinting approach that was successfully implemented to predict specific binding sites (operators) and target genes for the RRs of B. more...

(Submitter supplied) Aims: To investigate the inactivation kinetics of Bacillus cereus vegetative cells upon exposure to low-temperature nitrogen gas plasma and to reveal the mode of inactivation by transcriptome profiling. Methods and results: Exponentially growing B. cereus cells were filtered and put on agar plates. The plates, carrying the filters with the vegetative cells, were placed into nitrogen gas plasma at atmospheric pressure and cold temperature (~37°C). more...

(Submitter supplied) PlcR, the major virulence transcriptional regulator in the Bacillus cereus group belongs to the RNPP quorum sensor family and is activated through interaction with the secreted heptapeptide PapR7 used as a signalling molecule. We identified using modeling analysis a structural homologue of PlcR, PlcRa, in B. cereus. Whole-genome comparative microarrays identified 119 genes (threshold >3) differentially expressed at the onset of stationary phase in a plcRa mutant. more...

(Submitter supplied) Sorbic acid (SA) is widely used as a preservative, but the effect of SA on spore germination and outgrowth has gained limited attention up to now. Therefore, the effect of sorbic acid on germination of spores of B. cereus strain ATCC 14579 was analyzed both at phenotype and transcriptome level. Spore germination and outgrowth was assessed at pH 5.5 without and with 0.75, 1.5 and 3.0mM (final concentrations) undissociated sorbic acid (HSA). more...

(Submitter supplied) A common bacterial strategy for monitoring environmental challenges is to use two-component systems, which consist of a sensor histidine kinase (HK) and a response regulator (RR). In the food-borne pathogen Bacillus cereus, the alternative sigma factor σB is activated by the RR RsbY. Here we present strong indications that the PP2C-type phosphatase RsbY receives its input from the multi-sensor hybrid kinase BC1008 (renamed RsbK). more...
