摘要：
Azo dyes belong to the largest group of marketed colourants. Removal of dyes from effluents is the major environmental problem because certain aromatic compounds carrying HSO3- groups resist biodegradation or are incompletely degraded. In the present study microbial removal of azo dye Reactive Red 120 from aqueous solution was investigated. Mixed bacterial culture previously aerobically grown in the presence of this dye was used in static culture experiments. It was found that some ecological factors affected dye decolourisation. The fastest dye removal was obtained at 28 degrees C, pH = 6.8 with 0.20 volume fraction of culture inoculum and by addition 0.1 volume fraction of nutrient broth.
