摘要

The effects of biodegradable liquid of lignocelluloses on dye degraded by white rot fungus were investigated. Different dye media were used in screening fungal strains for their decolorizing ability. The strain P.ostreatus BP1 showed better decolorization compared to other fungus. When P.ostreatus BP1 was inoculated in some media containing biodegradable liquid from lignocelluloses, an obvious increase in the biomass of P.ostreatus BP1 and laccase activity was observed. Additionally, biodegradable liquid of lignocelluloses also accelerated dye biodegraded by white rot fungi in a medium containing malachite green and biodegradable liquid, the removal efficiency of malachite green could reach up to 94% rapidly in 6d and the ligninases activity increased more than 10 folds in contrast to the controls. The results also suggested that the mechanisms of accelerating dye biodegradation by biodegradable liquid of lignocelluloses might attribute to co-metabolism or enzyme-mediator system.
