abstract：:Manganese peroxidase (MnP) was produced by shallow stationary cultures of Phanerochaete chrysosporium growing on N-limited medium. Decolorization of sulfonphthalein (SP) dyes by MnP was investigated. The MnP activity profile and decolorization of SP dyes was correlated and almost all dyes were decolorized at pH 4.0. T...
