Mycotransformation of anthracene by indigenous Trichoderma lixii and Talaromyces pinophilus isolates: insights into the metabolic pathways, enzyme profiles and acute toxicity.

ABSTRACT: This study focused on the mycotransformation of a very prominent PAH, anthracene, and its acute toxicity reduction by Ascomycete fungi: Trichoderma lixii strain FLU1 (TlFLU1) and Talaromyces pinophilus strain FLU12 (TpFLU12), indigenously isolated from benzo[b] fluoranthene-enriched activated sludge. The results indicate that both the isolates TlFLU1 and TpFLU12 could tolerate anthracene exposure up to 1000 mg/L, with increased expression of ligninolytic enzymes: Laccase, Lignin peroxidase, and Manganese peroxidase. The mycotransformation of anthracene was observed to be growth-linked and mediated by the expression of the intracellular enzymes as the initial mechanism used by these strains followed by the ligninolytic enzymes with up to 56% and 38% anthracene degradation by TlFLU1 and TpFL
