摘要：

A degradation experiment on dibenzo-p-dioxin (DD) and 2,7-dichlorodibenzo-p-dioxin (2,7-DCDD) was carried out using basidiomycetous fungi belonging to the genera Coprinus, Coprinellus, and Coprinopsis. Some species showed a high rate of decrease in DD for the 2-week test period. Among them, Coprinellus disseminatus showed the highest ability to decrease the DD level, close to 100% by the end of 2 weeks. Further examination showed that Coprinellus disseminatus and Coprinellus micaceus, belonging to the genus Coprinellus, were able to metabolize 2,7-DCDD to a monohydroxylated compound, probably mediated by the P450 system. The metabolism of chlorinated DD by fungi capable of living in soil conditions is reported here for the first time.
