摘要：

Studies were carried out on the decolorization of Direct Red 28 (DR) and Direct Yellow 12 (DY) by developed bacterial consortium. Effects of pH, temperature, and NaCl concentrations on degradation were studied. GC-MS was used to detect the intermediates produced in the effluents of anaerobic step. The optimum pH and temperature for the degradation of DR and DY were pH 7 and 6, and 37 degrees Cand 45 degrees C, respectively. We observed the peak of benzenamine in GC-MS analysis. The products formed during the reduction of DY12 were benzenamine and 2-Amino-1-hydroxybenzene. The results showed a complete degradation of DY12 by the bacterial consortium.
