Role of azoreductase enzyme produced by potential Bacillus spp in decolourization of azo reactive red

摘要

Biological methods through bacteria are most feasible and ecofriendly alternatives for the degradation of xenobiotics compound especially azo reactive dyes. The potential Bacillus spp., isolated from the textile effluent contaminated sites. The enzyme azoreductase that catalyze the reduction of azo groups, the reactive azo dyes was purified and characterized by Bacillus pp., which is capable for the reduction or cleavage of azo bonds. It was found that the azoreductase from the bacterial strains was an inducible enzyme and play a key in dye degradation and the toxicity of degraded products was assessed by germination and growth of plant.
