The observed detrimental effect of photocatalysts on various microorganism groups decreases in the order: E. coli > S. aureus $\approx$ E. faecalis C. albicans $\approx$ A. niger. This sequence results most probably from differences in cell wall or cell membrane structures in these microorganisms and is not related to the ability of catalase production.pl
