BTEX compounds (benzene, toluene, ethylbenzene, and xylenes), from gasoline, aviation fuels, and industrial syntheses, frequently contaminate soil, sediments, and ground water. Both aerobic and anaerobic bacterial have been shown to degrade BTEX compounds, but no one pure strain of bacterial is known to degrade all components of BTEX efficiently. Phanerochaite chrysosporium, a naturally occurring wood-degrading white-rot fungus, has a versatile ability to degrade a wide spectrum of organopollutants. This paper investigates biodegradation of the BTEX components by P. chrysosporium. The results demonstrate that P. chrysosporium simultaneously degrades all the BTEX components and that this degradation is favored under nonligninolytic culture conditions when no designated lignin peroxidases(LIPs) and manganese-dependent peroxidases (MNPs) are produced.
