Ligninolytic fungi accomplish the partial degradation of numerous aromatic organopollutants. Their ability to degrade polycyclic aromatic hydrocarbons (PAHs) is particularly interesting because eukaryotes were previously considered to be unable to cleave fused-ring aromatics. Recent results indicate that extracellular peroxidases of these fungi are responsible for the initial oxidation of PAHs. Fungal lignin peroxidases oxidize certain PAHs directly, whereas fungal manganese peroxidases co-oxidize them indirectly during enzyme-mediated lipid peroxidation.
木质素分解真菌能够部分降解多种芳香族有机污染物。它们降解多环芳烃（PAHs）的能力尤其令人关注，因为真核生物此前被认为无法裂解稠环芳烃。最近的研究结果表明，这些真菌的细胞外过氧化物酶负责多环芳烃的初始氧化。真菌木质素过氧化物酶直接氧化某些多环芳烃，而真菌锰过氧化物酶在酶介导的脂质过氧化过程中间接共氧化它们。
