摘要：We have isolated 20 bacterial strains as a dye decolorizing micro-organisms. Out of 20 we have selectedone bacterial strain for further study. The selected bacterial strain was identifiedas Citrobacter sp. on the basis ofmorphological and biochemical tests. The UV–Vis analyses and colorless bacterial cells suggested that Citrobactersp.exhibited decolorizing activity through biodegradation, rather than inactive surface adsorption in liquid medium.TheCitrobacter sp. showed high decolorization activity in static condition as compared to shaking condition andthe effectof inoculum size on the decolourization of Magenta (100 ppm) by Citrobacter sp. indicated that increase the inoculumsize from 1-10 mL progressively decreases the time requirement for complete dye decolourization.These resultssuggest that the isolated organism Citrobacter sp.as a useful tool to treat waste water containing reactive dyes.
