RESUMEN

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. The influence of various inhibitors on Bromocresol Purple decolorization suggested an oxidative nature of the MnP-catalyzed decolorization of SP dyes.
