Abstract
Textile and dyeing industry emanates effluent, which contains azodyes that are found to have carcinogenic effects. Treatment of dyeing industry effluent has become a challenging task due to the high salinity levels and presence of non-biodegradable dyes. In this research study, a novel fungus, paecilomyces 7.)ariotii has been tried to degrade the dye house effluent. The effects of operating parameters such as initial concentration of effluent, concentration of carbon source, concentration of nitrogen source and effluent pH on the °A COD removal were determined. A kinetic model was established giving the dependence of COD removal rate on effluent COD (first order) and Biomass concentration (first order). The specific COD removal rate was evaluated as k=0.4566 1 at 32°C gDCM h
