Pure cultures of a penicillium species metabolize pyrenequinones to inextractable products

摘要

Quinones are major metabolites resulting from the oxidation of polycyclic aromatic hydrocarbons (PAHs) by fungi. Previously we established that the soil fungus Penicillium janthinellum SFU403 (SFU403) oxidizes pyrene to 1,6- and 1,8-pyrenequinones (PQs). Since many PAH quinones, including PQs, are known mutagens, we investigated the fate of PQs in pure cultures of SFU403. SFU403 converts approx approx 100
