Abstract

ABSTRACT The sigB gene of Bacillus cereus ATCC 14579 encodes the alternative sigma factor σ B . Deletion of sigB in B. cereus leads to hyperresistance to hydrogen peroxide. The expression of katA , which encodes one of the catalases of B. cereus , is upregulated in the sigB deletion mutant, and this may contribute to the hydrogen peroxide-resistant phenotype.
