The decolorization potential of the consortium HM-4 constituted by mixing four laboratory isolates identified as Bacillus cereus (BN-7), Pseudomonas putida (BN-4), Pseudomonas fluorescens (BN-5) and Stenotrophomonas acidaminiphila (BN-3) was compared with that of individual isolates. Six different azo dyes viz., C.I. Acid Red 88 (AR-88), C.I. Acid Red 119 (AR-119), C.I. Acid Red 97 (AR-97), C.I. Reactive Red 120 (RR-120), C.I. Acid Blue 113 (AB-113) and C.I. Acid Brown 100 (AB-100) were used in this study. The individual bacterial isolates were not able to completely decolorize these dyes, except for dyes AR-119 and AB-113. The consortium HM-4 was able to decolorize all the dyes used at an initial dye concentration of 20 mg L−1 at a significantly higher rate as compared to that achieved by individual isolates.
