Spores of Botrytis cinerea can germinate in the presence of up to 180 mM hydrogen peroxide and its mycelium can develop in the presence of even higher concentrations. The mycelium can breakdown hydrogen peroxide present in its culture medium rapidly in a time‐dependent manner. This breakdown depends on the composition of the culture medium, is not inhibited by inhibitors of catalase activity, but is considerably reduced by inhibitors of peroxidase, such as benzhydroxamic acid, and by caffeic acid. In addition, growth in the presence of inducers of laccase formation appears to promote subsequent breakdown of hydrogen peroxide.
