Effect of temperature and inhibitors on sporulation and the calcium accumulation system in Bacillus megaterium

Heat shock applied early in sporulation affects heat resistance of Bacillus megaterium spores

“…Spores of Bacillus spp. are more resistant against heat inactivation at about 40°C than are vegetative cells, but the process of sporulation is suppressed by temperatures of about 4 to 5°C lower than is growth (2,4,9). Heat resistance of spores is due predominantly to dehydration of the spore protoplast, to an increased concentration of Ca2 , probably also to the structure of spore membranes and to other factors (1, 2).…”
