ABSTRACT: The potential of different bacteria to decolorize textile waste effluents of Hindoostan mill, Karad, Maharashtra, India was evaluated under this research. Growth, Decolorization, COD and BOD were determined under controlled condition using textile waste effluent as growth medium supplemented with mineral salts. Higher decolorization was observed when a mixed culture of Bacillus subtilis and Micrococcus species was used at the pilot scale of process. This study demonstrated the use of mixed culture of bacterial species to degrade textile reactive dyes and reinforces the potential of this group of bacteria for the decolorization of various textile effluents.

KEYWORDS: Textile waste effluent; Decolorization; Bacterial Isolates; COD; BOD
