Abstract
Decolorization of triphenylmethane dye (crystal violet) by white-rot fungi – Stereum ostrea and Phanerochaete chrysosporium
was investigated in liquid medium for a period of 10 days under shaking conditions. S. ostrea exhibited maximum decolorization
crystal violet 90% in comparison with P. chrysosporium that it was 67% at 0.01% concentration on the 8th day of incubation.
S. ostrea dominates P. chrysosporium on the production of biomass and protein content. The fungal cultures were tested for the
production of ligninolytic enzymes – laccase (Lcc), lignin peroxidase (LiP), and manganese peroxidase (MnP). Fungal cultures
grew well in dye-containing medium and exhibited decolorization of crystal violet confirming the presence of ligninolytic
enzymes. S. ostrea displayed maximum Lcc (49 U/ml), LiP (0.34 U/ml), and MnP (48 U/ml) against P. chrysosporium.
