Azo dyes square measure used widely within the manufacture of varied goods like animal skin, textile, plastics, paper, hair care merchandise and cosmetics. chemical (group) dyes square measure the most important group of dyes utilised in trade representing over half the annual production. it's been calculated that 100% of the dye stuff throughout this dying method doesn't bind to the fibres and is so discharged into the waste product or setting. Chemical group dyes have structural properties that aren't simply degradable beneath natural conditions..Over the past year many bacterial strains have been studied for their abilities to decolorization and detoxify dyes. Considerable attention has been given in evaluating the capability of microorganisms in decolorizing and degrading azo dyes. The effectiveness of microbial decolorization depends on the adaptability and activity of selected microorganisms.this study work is to isolate some microbial strains, which possessed the ability to decolorize simulated effluent containing dyes covering various classes like mono-azo /diazo/triazo, acidic, reactive, sulphonated/ non sulfonated dyes, direct dyes, Reactive dyes and triphenylmethane dyes. The isolates showing significant decolorization were identified to ascertain their taxonomic position. From textile effluents nineteen (5 Actinomycetes & fourteen Bacteria) microbic species were isolated. Once screening the foremost economical 3 cultures square measure elite for additional study out of them one was microorganism and 2 square measure actinomycetes. All 3 species will decolour and detoxify 'Acid dyes'(Methyl red), 'Reactive dyes' (Reactive red-195, Reactive black five. Reactive yellow-145), Triphenylmethane dye (Malachite green) and simulated effluent (Mixture of ten dyes). In order to check physiological and metabolic aspects of the decolorization and detoxification method Reactive yellow- 145was elite as a model dyestuff beneath static and shaking conditions. Once optimised for chemical science parameters, microorganism pure cultures show 94% decolorization among 3 days beneath stationary conditions and Actinomycetes pure cultures show 91 % look after decolorization among five days beneath shaking conditions.
