Malachite green and crystal violet were removed by adsorption (due to biosorption) on rice straw and then biodegraded by white rot fungus. The effects of liquid-solid contact (rotation rate), biomass dose, dye concentration, size of the rice straw particle and pH on the adsorptive capacities were determined. The rice straw exhibited high capacities for the dyes, up to 31.89 mg/g of malachite green and 52.98 mg/g of crystal violet were observed in the study. The adsorbed dyes were degraded by the inoculated white rot fungus; 93.67% of the ad...
