Suchita Dahiwade, Dr. A. O. Ingle, Dr. S. R. Wate

Abstract :

The isolated Bacillus species was found to decolourize commercial azo dye Acid red 14. The isolate could decolourize the azo dye upto 300 mg/l in minimal medium without nutritional supplements. Effect of various nitrogen sources beef extract, yeast extract, peptone at 0.05% and ammonium nitrate, sodium nitrate and ammonium chloride at 0.1 % and in combinations were studied on decolourization of the Acid red 14 by Bacillus species. 81% decolourization was observed in the presence of 0.1% of ammonium chloride in combination of 0.05% yeast extract as compared to other nitrogen sources. The decolourization was monitored for 72 h using the UV-Vis spectrophotometer.
