Among the nwenty bacterial strains isolated from the effluent water of a textile mill in central Iran, one was able to decolorize Secrilene Black (Disperse Black) dye, (range : 10–100 mg\l), present in artificial or real effluents. Biolchemical characterization indicated that the strain is an aerobic strain of Bacillus sp. Studies via NMR and FT.IR and GC–MS showed that decolorization occurs by viable and active cells within 30 min (cell biomass \ dye: 5\1) without any need for extra carbon of nitrogen sources, whereas biodegradation takes place in 7 days. Studies showed that bioremediation occurs via a mechanism that is heretofore unreported , eg unaffected by inhibitors like menadione, sodium azide, di–nitrophenol and jodosobenzoic acid, products of biodegradation are non–toxic against the PS bacteria, juman cells and Phanerochate chrysosporium (PTCC 5130) . It is thus concluded that SP strain could be advantageously utilized for the treatment of effluents containing Serilene Black dye.<\div>
