Cunninghamella elegans grown on Sabouraud dextrose broth in the presence of naphthalene produced six metabolites. Each product was isolated and identified by conventional chemical technique. The major metabolites were 1-naphthol (67.9 percent) and 4-hydroxy-1-tetralone (16.7 percent). Minor products isolated were 1,4-naphthoquinone (2.8 percent), 1,2-naphthoquinone (0.2 percent), 2-naphthol (6.3 percent), and trans-1,2-dihydroxy-1,2-dihydronaphthalene (5.3 percent). C. elegans oxidized both 1-naphthol and 1,4-naphthoquinone to 4-hydroxy-1-tetralone. The results suggest that C. elegans oxidizes naphthalene by a sequence of reactions similar to those reported for the mammalian metabolism of this hydrocarbon.
