Past Research Interest

Mechanism of heat resistance of bacterial endospores and initiation of microcycle sporulation in Bacillus subtilis. Induction of mutations by heat and the decreased resistance of DNA-repair-deficient mutant spores point to DNA involvement in the heat resistance of spores; requirement of S-adenosylmethionine for microcycle sporulation suggests methylation involvement in the initiation of sporulation.
