title: Decolorization of synthetic dyes by the deuteromycete Pestalotiopsis guepinii CLPS no. 786 strain.
abstract: The ability of Pestalotiopsis guepinii CLPS no. 786 to decolorize 13 dyes of varied structure was analyzed and compared with that of the basidiomycete Phanerochaete chrysosporium . Nine dyes representing anthrapyridone, azo, N-heterocyclic and triphenylmethane chromophores, but none with the O-heterocyclic group, were decolorized by P. guepinii when added to an agar medium. Studies with liquid cultures revealed that P. guepinii transformed both crystal violet and methylene blue B dyes, and adsorbed different chromophores onto its mycelium.
