Isolation, identification and decoloring capability of an Acid Red 3R decoloring bacterial strain

A bacterial strain M3 with remarkable ability to decolorize the Acid Red 3R was isolated from anaerobic sludge by the method of the concentration gradient domestication. The strain was identified as Enterobacter cloacae according to its morphological characters and 16S rRNA gene sequences analysis. Experiments on the effect of decolorization conditions were carried out under anaerobic condition. The results showed that the best nutrient source …
