چکیده:

Water pollution is one of the major problems faced by the humanity worldwide. The major route of water pollution is factory effluent, which includes organic and inorganic nutrients, infectious agents and toxic organic and inorganic compounds. Dye processing industry produces effluent which contains color compounds, suspended solids, acids, chlorine dyes, chromium, phenolic substances and comprise high BOD. Around 15% of the dyes originally introduced into the fiber-dyeing bath are discharged into the effluent system and ultimately reaches water bodies. A number of microorganisms are extensively investigated for dye degradation. The present study deals with the biodegradation of coir dyes using Phanerochaete chrysosporium (MTCC 787), Trametes hirsuta (MTCC 136), Arthrographis KBF2 sp andEnterobacterKBB4.Arthrographis KBF2 sp was found to be the most efficient organism in dye degradation.The degradation was primarily by adsorption to the biomass and gradual degradation thereafter.The present study confirmed that microbial degradation of dyes could be vital to our success in solving the detoxification of hazardous pollutants of water.
