The metabolism of α-naphthol by Aspergillus niger PTCC 5011, a fungi isolated in Ardebil, Iran, from industrial wastewater, was studied. A. niger metabolized approximately 80% of α-naphthol within 5 days. The identification and quantification of degradation products using GC-MS demonstrated that approximately 41% of the parent compound was converted into 1-ethyl-2-methyl benzene, 7.43% was converted into acetonaphthone, 5.55% was transformed into 4-hydroxy-1-naphthyl sulfate, 3% into 1,4-naphthoquinone, and about 6.68% into 2-phenyl-1,2,3-tetrahydro-1-naphthol. These results support a role for A. niger in affecting the environmental fat of pollutants in ecosystems.
