Laccase of Trametes versicolor in combination with 1-hydroxybenzotriazole (HBT) was able to oxidise two polycyclic aromatic hydrocarbons, acenaphthene and acenaphthylene; both compounds were metabolised completely after 70-h incubation. Laccase alone oxidised about 35 % of the acenaphthylene and only 3 % of the acenaphthene. Single compounds found in a complex mixture of oxidation products were identified. Main products detected after the incubation were 1,2-acenaphthenedione and 1,8-naphthalic acid anhydride. The proposed oxidation pathway seems to be analogous to the metabolism reported for bacteria and mammals.
