Abstract

In the present study, an attempt was made to examine the potential of marine actinomycets for decolorization of amidoblack azo dye. Actinomycetes from marine sediment and dye waste were subjected to decolorization under aerobically at 5, 10 and 100 ppm. Effectiveness of azo dye decolorization was determined by UV–Visible spectrum and High Performance Liquid Chromatography (HPLC). Biochemical properties and carbohydrates assimilation studies revealed that the isolated organism designated as Micromonospora sp, Streptomyces sp and Micropolyspora sp. The significant decolorization (88%) of amidoblack was found at 5ppm and moderately at 10 ppm (66%). Decolorization potential increased the applicability of these marine actinomycetes for the dye removal. The present work was concluded that the marine actinomycets can be used as a useful tool to treat waste water containing reactive dyes
