Visualization of Germination Proteins in Putative Bacillus cereus Germinosomes.

ABSTRACT: Bacillus cereus can survive in the form of spores for prolonged periods posing a serious problem for the manufacture of safe shelf-stable foods of optimal quality. Our study aims at increasing knowledge of B. cereus spores focusing primarily on germination mechanisms to develop novel milder food preservation strategies. Major features of B. cereus spores are a core with the genetic material encased by multiple protective layers, an important one being the spores' inner membrane (IM), the location of many important germination proteins. To study mechanisms involved in germination of B. cereus spores, we have examined the organization of germinant receptors (GRs) in spores' IM. Previous studies have indicated that in spores of B.cereus ATCC 14579 the L-alanine responsive GR, GerR, plays a ma
