Prospecting Multiple Enzyme Systems of Mangrove Fungi for Dye Decolourization Potential

Decolourisation of effluents is always a major issue in the effluent treatment process. There are many methods for the decolourisation of these effluents. Enzymatic decolourisation is one of the promising methods. Laccase, one of the major enzymes involved in decolourisation mechanism is produced by many microbial sources. In the present study Trichoderma viride, a known plant growth promoting fungal isolate obtained from mangrove ecosystem of Valanthakad, Kerala, India was found to produce laccase enzyme. Plate assay was performed for evaluating the decolourising ability using different synthetic dyes. A higher decolourisation was observed at various dye concentrations. The isolate was found to be efficient in decolourization of synthetic dyes effectively through enzymatic method. The fungal dye biosorption was also studied using the isolate and it was found that there was high efficacy for laccase system in dye decolourization.
