Bacterial Consortium PMB11 showed 91% decolorization of textile dye Navy blue HE2R (50 ppm) in liquid broth within 6 h. The higher decolorization rate (75.8) was observed with bacteria consortium than the individual strains. The immobilized consortium PMB11 were showed complete decolorization of dye solution in flask within 15 h. The column was run for 7 days continuously passed dye solution (50 ppm) through column. The beads were viable for seven days in column that showed the efficiently decolorizing activity. Immobilized consortium PMB11 degraded Navy blue HE2R into different metabolites was confirmed by various analytical techniques like UV-vis spectroscopy, FTIR and HPLC.
