White rot fungi capable of decolourising textile dyes under alkaline conditions

Abstract

Four different white rot fungi were screened to study the decolourisation of the textile dyes Reactive Black 5 (RB5) and Poly R-478 on plates under alkaline condition. Three strains of Trametes versicolor (MUM 94.04 MUM 04.100 MUM 04.101) and one strain of Phanerochaete chrysosporium (MUM 94.15), showed better decolourisation results. The strains were used for decolourisation study in liquid culture medium (LCM). All four strains presented more efficient decolourisation on dye RB5, but they differed in decolourisation capacity depending on the analised pH value. In LCM the decolouration of dye reached 100% for the two strains of WRF studied.
