Article: Laccase mediated bioremediation of industrial dyes by a potent strain of Arthrographis sp. Journal: International Journal of Environment and Waste Management (IJEWM) 2022 Vol.29 No.3 pp.278 - 290 Abstract: Water pollution is one of the major problems faced by 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 colour compounds, suspended solids, acids, chlorine dyes, chromium, phenolic substances and comprise high BOD. Around 15% of the dyes originally introduced into the fibre-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 KSF2 sp (MTCC 8880) and Enterobacter cloaceae KSB4 (MTCC 9145). Arthrographis KSF2 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 for the success in detoxification of hazardous pollutants of water.

Abstract: Water pollution is one of the major problems faced by 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 colour compounds, suspended solids, acids, chlorine dyes, chromium, phenolic substances and comprise high BOD. Around 15% of the dyes originally introduced into the fibre-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 KSF₂ sp (MTCC 8880) and Enterobacter cloaceae KSB₄ (MTCC 9145). Arthrographis KSF₂ 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 for the success in detoxification of hazardous pollutants of water.
