Studies On Immobilized Yeast For Decolorization Of Azo Dyes Abstract: Azo dyes that are extensively used in textile industries are recalcitrant xenobiotic compounds causing a serious damage to the environment Degradation of azo dyes being a necessity diverse dye dumped soils were screened for dye degrading yeasts One efficient yeast isolate capable of decolorizing both mono-azo dyes and di-azo dyes was selected, immobilized by entrapment method and
