Heat, hydrogen peroxide, and UV resistance of Bacillus subtilis spores with increased core water content and with or without major DNA-binding proteins.

Abstract excerpt

Spores of a Bacillus subtilis strain with an insertion mutation in the dacB gene, which codes for an enzyme involved in spore cortex biosynthesis, have a higher core water content than wild-type spores. Spores lacking the two major alpha/beta-type small, acid-soluble proteins (SASP) (termed alpha-beta- spores) have the same core water content as do wild-type spores, but alpha-beta- dacB spores had more core water...
