Influence of sporulation medium composition on transcription of ger operons and the germination response of spores of Bacillus cereus ATCC 14579
Article Abstract:
The transcriptional analysis of each of the seven ger operons of Bacillus cereus ATCC 14579 during sporulation in nutrient-rich Y1 medium, containing approximately 30 mM amino acids and 10 mM glucose, and in modified medium, containing approximately 14 mM amino acids and no glucose is described. The composition of the medium was found to have significant affect on expression of the B. cereus ger operons and the spores' nutrient-induced germination characteristics.

Quantitative analysis of population heterogeneity of the adaptive salt stress response and growth capacity of Bacillus cereus ATCC 14579
Article Abstract:
A quantitative analysis of population heterogeneity of the adaptive salt stress response and growth capacity of Bacillus cereus ATCC 14579 was conducted. It was found that exposure to mild salt stress resulted in growth characterized by a remarkably low variability of microcolony sizes and under severe salt stress conditions, the microcolony sizes were highly heterogeneous.

Air-liquid interface biofilms of Bacillus cereus: Formation, sporulation, and dispersion
Article Abstract:
Various assays and culture conditions and a range of strains used to study the roles of strain diversity and environmental conditions showed that Bacillus cereus biofilms could act as a nidus for spore formation and subsequently release their spores into food production environments.
