Various textile industries are discharging toxic effluents containing azo dyes and they adversely affect the aquatic life, water resources, soil fertility and ecosystem integrity. With the goal of using microorganisms as the agent for the bioremediation in the waste water treatment containing dye has been done over the last two decades, to our best of knowledge considerable work has been not been done using actinomycetes in the treatment of dye containing waste water. In the present study, actinomycetes strain namely Micromonospora sp were isolated from textile effluent adopted soil of Tiruppur district, Tamil Nadu, India and screened for their ability to decolourize Reactive Red 35 at different parameters includes pH, agitation, nitrogen source and medium. Comparision of decolourising capacity data revealed that more effective decolorization occurs by using minimal media with peptone under static and moderately decolourised under shaking condition. The decolourising capability is found to be high at pH 8 followed by pH 6. FTIR spectrum was compared between the spectrum of RR35 and the products obtained after decolorization confirmed the biodegradation of dye. This decolorization potential suggests the applicability of this isolate for dye removal in effluent from textile industries.
