LACCASE PRODUCTION BY NEWLY ISOLATED GANODERMA LUCIDUM WITH SOLID STATE FERMENTATION CONDITIONS AND ITS USING FOR DYE DECOLORIZATION

Laccase production capacity of newly isolated fungus Ganoderma lucidum was studied during solid state fermentation on substrates. Because wheat bran detected as the most effective substrate, effect various culture parameters and some inducers laccase in media investigated. Wheat with moisture content 75%, pH 5.0 30 °C medium 10 mM copper addition supported highest amount laccase. In glass tray fermenter 2973±220 U/L activity obtained. Crude gave at 70 °C. It stable 60°C for 6 hours retained 37% 2 hours. decolorized 61% Remazol Brilliant Blue R within 20 min. Results showed that this strain could produce high suitable inducer such induce its production. The crude obtained be used textile dye decolorization applications.
