In the current era dyes play a vital role in industries. Extensive uses of dyes have led to enormous risks to all species including human beings. Biological treatment of these dyes is one of the most versatile options we have. This work is based on the utilization of microorganisms endowed with degrading abilities for the detoxification of harmful dye. The mixed cultures of Escherichia coli and Bacillus species are compared for their ability to degrade the dye. Experiments were conducted at 2 glucose concentrations (1 and 2 g/l) and three dye concentration (20, 30 and 50 ppm). Results show that dye degradation was most effective at 1 g/l glucose concentration. Although glucose is universally biodegradable compound, there is a complex interaction between different primary substrates and intermediate products resulting in contradicting effects. The results were also compared with immobilized cells of E. coli and Bacillus species. Moreover, there was variation in effect of glucose concentration on the degradation. In both cases, higher degradation was achieved at 2 g/l glucose concentration.
