摘要：

Experiments in homogenous solution confirm previous findings that catalase is an effective oxidant for Hg-0 -> Hg2+. Peroxidase also effects the oxidation, and in both oxidations the co-substrate hydrogen peroxide is not essential for mercury oxidation, although the oxidation is enhanced by the presence of hydrogen peroxide.
