Comparison of remazol brillant blue removal from wastewater by two different organisms and analysis of metabolites by GC/MS

Abstract

White rot fungus participates in biological degradation of many organic environmental pollutants. Also, white rot fungus contains a variety of extracellular enzymes, and these enzymes are used for biological degradation of organic matter. We investigated the biological treatment of synthetic dyes, at a low cost and in the shortest possible time, that are used especially in the dye and textile industries and are important polluting agents in the wastewater discharged into the environment by these industries. For this purpose, removal of Remazol Brillant Blue by Pleurotus ostreatus and Coprinus plicatilis was studied. This dye was removed 100% (dye concentration, 10.0 mg/L) by both organisms. Laccase and manganese peroxidase enzyme activities were also monitored. There was an attempt to identify metabolites via GC/MS at the end of the decolorization. No detectable metabolite was found.
