Question

Calculate decolorization of dyes by microorganisms

Answer 1

A developed consortium-GR, consisting of Proteus vulgaris NCIM-2027 (PV) and Micrococcus glutamicus NCIM-2168 (MG), completely decolorized an azo dye Scarlet R under static anoxic condition with an average decolorization rate of 16,666 μg h−1; which is much faster than that of the pure cultures (PV, 3571 μg h−1; MG, 2500 μg h−1). Consortium-GR gave best decolorization performance with nearly complete mineralization of Scarlet R (over 90% TOC and COD reduction) within 3 h, much shorter relative to the individual strains.
