Optimization of process conditions for decolorization of azo dye by an efficient broad-spectrum dye decoloring bacteria strain

Decolorization of textile azo dye Acid Red 3R was carried out from simulated aqueous solution by a broad-spectrum decoloring strain Enterobacter cloacae strain M3.Based on the single factor experiment, response surface methodology involving Box-Behnken design matrix in three most important operating variables: temperature, initial dye concentration and yeast powder concentration was successfully employed to study interaction effects of …
