The objective of this study was to decolorize the cotton industry waste water effluents by treatment with microorganisms like Ganoderma lucidum and Arachniotus sp. to an extent to make it least harmful to water habitats and also to make it fit for irrigation purposes. The influencing parameters that affect the percentage of decolorization rates are optimized in still culture fermentation. Spectrophotometric analysis method was used to estimate decolorization of textile industry effluent at its ?max (410 nm). The optimal values of the parameters such as effluent to water ratio, fermentation time, pH, and carbon to nitrogen ratio are found to be 1:0, 72 hours, 6.0, and 1: 2.33 respectively. The concentration of different ions like Ca+2, Mg+2 and H2PO4-1 were also optimized for maximum decolorization and the optimized conc. were 0.05%, 0.05% and 0.1% for Arachniotus sp. and 0.1%, 0.05% and 0.1% for Ganoderma lucidum respectively. The maximum percentage of decolorization at the optimized conditions on large scale was found to be 82.24% and 81.32 % with Arachniotus specie and Ganoderma lucidum respectively.
