When TNT was added into a nutrient-rich YMG medium at the beginning of the incubation, four of the fungal strains completely removed TNT during several days of incubation and showed higher removal rates than those of Phanerochaete chrysosporium. TNT added into YMG medium after a 5-day preincubation period completely disappeared within 12 hours, and the removal rates were higher than those in N-limited minimal medium. Isomers of hydroxylamino-dinitrotoluene were identified as the first detectable metabolites of TNT. These were transformed to amino-dinitrotoluenes, which also disappeared during further incubation from cultures of Irpex lacteus. During the initial phase of TNT degradation by I. lacteus, dinitrotoluenes were also detected after the transient formation of a hydride-Meisenheimer complex, indicating that I. lacteus used two different pathways of TNT degradation simultaneously.
