Azo dyes are a widespread class of poorly biodegradable industrial pollutants. In anaerobic environments, azo bonds are reductively cleaved yielding carcinogenic aromatic amines, many of which are assumed to resist further metabolism by anaerobes bacteria. The latter compounds generally require aerobic conditions for their degradation A reactive group of azo dye called C.I: Reactive Red was found to be degraded using Pseudomonas spp. MPS-79 to α-ketoglutaric acid with transient accumulation of 4-aminobenzenesulfonic acid (sulphanilic acid), 4-amino, 3-hydronaphthalenesulfonic acid and 4-amino, 5-hydronaphthalene 2,7 disulfonic acid as a degradation intermediate in anaerobic facultative batch culture. Color and Total Organic Carbon (TOC) was successfully removed more than 95% and upto 50% resp. There is no significant correlation between pH and oxygen depletion since there is slightly change in pH was observed (pH from 7.21 to 7.25) though the anaerobiosis was found developed throughout the experiment (redox potential from 0.7 to 1.6 mV). The anaerobic metabolism of glucose as co-metabolite also shown to provide the electrons required for the initial reductive cleavage of the azo group. This finding suggest that it is possible to mineralize the azo dye in the environment; thereby, avoiding accumulation of toxic intermediates in the water.
