Degradation of 4-nitrophenol by the white-rot polypore Trametes versicolor

The ability of Trametes versicolor strain BAFC 2234 to degrade 4-nitrophenol in vivo and in vitro was evaluated. T. versicolor grew in the presence of 0.5 mM 4-nitrophenol and degraded 98.4% of this toxic compound in less than 96 h. The strain secreted different ligninolytic oxidoreductases such as...
