EVALUATION OF BACTERIA RESPONSIBLE FOR DECOLOURIZATION OF METHYLENE BLUE DYE IN SOIL

POONAM PAL AND HARDIK PATEL

Abstract

The discharge of textile effluents in open streams and land poses serious environmental problems. Even after physical and chemical treatment colour removal is not 100% achieved and hence it causes environmental pollution. The present study deals with examination and isolation of potential mycorrhizal soil bacteria responsible for decolorization of Methylene blue dye which is an azo dye. The results showed Bacillus haynesii strain NRRL B-41327 and Bacillus licheniformis strain DSM 13 were responsible for decolorization of Methylene blue dye in mycorrhizal soil. These gram positive, rod shaped bacteria in consortium exhibited 52.30 % colour removal efficiency. Potential of these bacteria can be further exploited for removal of residual dyes from textile effluents for restoration of ecosystem in an eco-friendly way which will be cost effective too.
