Decolorization of synthetic dyes by the deuteromycete Pestalotiopsis guepinii CLPS no. 786 strain.
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.
