Different types of edible mushrooms like Agaricus, bisporus, A. bitoriqus, Pleurotus spp., Volvariella volvacea, Lentinula edodes, Calocybe indica, Flamullina, Ganoderma lucidum etc. are cultivated in industrial scale. Majority of edible fungi secretes extracellular Ligninocellulolytic enzymes like Laccase, lignin peroxidase, manganese peroxidase, cellulase etc. for effective conversion of ligninocellulolytic substrate to compositing form which led to fruiting of mushrooms. Consequently, an adequate disposal method is needed for the high quantities of spent mushroom substrate (SMS) generated in this agro-food industrial activity. On the other side, textile industry among the largest water consuming industries in the world and approximately, 10,000 different dyes and pigments are used at industrial scale. It is estimated that nearly 40% of the total dyes used in the dyeing process may find their way in wastewater. So, there is an attempt to utilize the ligninolytic enzymes rich SMS of different mushroom for efficiently biodegradation of textile wastewater & polyaromatic pollutants.
