title: Effective bioremoval and detoxification of textile dye mixture by Alishewanella sp. KMK6.
abstract: Alishewanella sp. strain KMK6 was able to degrade mixture of textile dyes (0.5-2.0 g l(-1)) within 8 h. An initial 28 % reduction in COD was observed immediately after decolorization at static anoxic conditions which on further incubation at shaking conditions reduced by 90 %. Partially purified azoreductase was able to utilize different azo dyes as substrates. The HPLC profile of dye degradation showed formation of metabolic products. Further FTIR analysis showed significant changes in the peaks corresponding to functional groups present in dye mixture and its degradation products. The genotoxicity assessment showed that the dye degradation products were non-toxic compared to dye mixture.
