Azodyes are potential chemical pollutants of industrial origin. The effect of pH and starvation of certain nutrients on biodegradation of reactive azodyes- Procion Brilliant Red H-E7B (Reactive Red 141), Procion Yellow H-E4 (Reactive yellow 84), Procion Navy Blue H-ER (Reactive blue 171) were studied. The high percentage of degradation was achieved at dye concentrations 12 mg L^-1 for procion brilliant red i.e. 64.16%, 14 mg/l for procion navy blue and procion yellow dyes 76% and 57.14%respectively. The Nutrient limited media having 0.5% glucose, 0.06% Aspargine, 0.2% MgSO₄7H₂O and 0.5% KH₂Po4 at a pH-4.5 was found to be very effective for the degradation of selected dyes.
