Abstract

Spores of Bacillus subtilis are significantly more resistant to wet heat than are their vegetative cell counterparts. Analysis of the effects of mutations in and the expression of fusions of a coding gene for a thermostable β-galactosidase to a number of heat shock genes has shown that heat shock proteins play no significant role in the wet heat resistance of B. subtilis spores.
