Bacillus cereus isolated from dye industrial waste, that is, effluent and soil samples was screened for its ability to decolourize two reactive azo dye – cibacron black PSG and cibacron red P4B under aerobic conditions at pH 7 and incubated at 35°C over a five day period. Different carbon and nitrogen sources were used for the decolourization study. B. cereus was able to decolourize cibacron red P4B by (81%) using the combination of ammonium nitrate and sucrose, while it decolourizes cibacron black PSG by (75%) using yeast extract and lactose.
