(Submitter supplied) The food-borne human pathogen Bacillus cereus is found in environments that often have a low pH, such as food and soil. The physiological response upon exposure to several levels of acidity were investigated of B. cereus model strain ATCC 10987, to elucidate the response of B. cereus to acid stress. pH 5.4, pH 5.0, pH 4.8 and pH 4.5 were selected to conduct microarray analyses, based on the differences in physiological response upon exposure to the acid conditions. more...

(Submitter supplied) Comparative phenotype and transcriptome analyses were performed with Bacillus cereus ATCC 14579 exposed to acid down-shock to pH 5.5 set with different acidulants. When acidified with hydrochloric acid (HCl), growth was diminished, whereas 2 mM undissociated lactic acid (HL) or acetic acid (HAc) stopped growth without inactivation (bacteriostatic condition), and 15 mM undissociated HAc caused growth arrest and, finally, cell death, as reflected by a 3 to 4 log inactivation (bactericidal condition). 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) Antimicrobial chemicals are widely applied to clean and disinfect food-contacting surfaces. However, the cellular response of bacteria, such as Bacillus cereus, to various disinfectants is unclear. In this study, the physiological and genome-wide transcriptional responses of B. cereus ATCC 14579 exposed to four different disinfectants (i.e., benzalkonium chloride, sodium hypochlorite, hydrogen peroxide, and peracetic acid) were analyzed. more...

(Submitter supplied) Bacteria are able to cope with the challenges of sudden increase of salinity by activating adaptation mechanisms. In this study, exponentially growing cells of the food-borne pathogen Bacillus cereus ATCC 14579 were exposed to both mild (2.5% NaCl w/v) and severe (5% NaCl w/v) salt stress conditions. B. cereus continued growth at a reduced rate when shifted to mild salt stress. Exposure to severe salt stress resulted in a lag period, and after 60 min cellular growth was resumed filamentously. more...
