    Due to the prevalence of horizontal gene transfer among bacteria, the pan-genome of B. cereus is continually expanding. [23] The GC content of its DNA across all strains is approximately 35%. [24] Following exposure to non-lethal acid shock at pH 5.4-5.5, the arginine deiminase gene in B. cereus, arcA, shows substantial up-regulation.
