Description A novel three-step technology for treatment of four molasses-based raw industrial effluents, varying in their COD, color and turbidity is reported here. Sequential steps involved in this treatment are; (1) sonication of the effluents, (2) whole-fungal treatment of these by a ligninolytic marine fungus and (3) biosorption of the residual color with heat-inactivated biomass of the same fungus. Sonication reduced the foul odor and turbidity of the effluents. It increased biodegradability of the effluents in the second stage of treatment. Laccase production in the presence of all the four effluents was directly correlated with their decolorization. After the third step, a reduction of 60-80% in color, 50-70% in COD and 60-70% in total phenolics were achieved. Comparative mass and nuclear magnetic resonance spectra indicated increasing degradation of the effluent components after each stage. Toxicity (LC sub(50) values) against Artemia larvae was reduced by two to five folds
