Abstract:

Synthetic dyes are extensively used in textile industries and other industries. Methyl orange is one such azo dye, which is widely used in textile industries and also as an indicator in chemical laboratories. This study focuses on the capability of Bacillus sp. Strain AK1 to decolorize Methyl Orange dye. Various parameters like time course, initial dye concentration, pH and temperature were optimized to achieve maximum decolorization of the dye. The bacterium exhibited remarkable color removable capability over a wide range of dye concentration, pH and temperature. The bacterial strain decolorized Methyl orange (200mg/l) upto85% in 24 hours of incubation at pH7 and temperature 370c. The efficiency decreased with the increase in initial dye concentration. The pH also had a great impact upon the decolorizing ability.
