Abstract

NH4+-N was choiced as an influence factor for analysis the effect on the laccase activity from the white rot fungus Pleurotus ostreatus and indole degradation. The experiments were performed with different NH4+-N concentration, with a focus on the indole degradation by laccase in the presence of 2,2-Azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) or not. Results showed that NH4+-N had a positive effect on laccase activity and also enhanced the degradation of indole. Meanwhile, NH4+-N was oxidized to NO2-.
