Sri Lanka is considered to be one of the world’s leading apparel producers. The textile industry utilizes large volumes of water in its processing operations and generates substantial quantities of dye containing waste water which is usual I y discarded into water bodies mostly without feather treatments. About I 0- I 5% of all dyes are directly lost to wastewater in the dying process and removal of color front effluent is one of the major problems that the textile industry faces. The presence of color in water tinder’s the absorption of solar radiation, thus reducing the natural photosynthetic activity, causing changes in aquatic biota. Furthermore, textile dyes pose serious health threats to humans due to their carcinogenicity and lead to mutagenic and toxic effects on organisms. Amongst many classes of synthetic dyes, triphenyl methane group of dyes such as crystal violet and malachite green are the most used iii the textile and dyeing industries (Bumps and Brock, 1988).The decolonization and degradation of textile dye effluent does not occur when treated with conventional effluent treatment systems (Murugesan et at., 2007). Use of microorganisms to remove dyes from industrial effluents or bioremediation is inexpensive and the end products of complete mineralization are nontoxic. Basidiomycete fungi produce an array of extracellular enzymes helpful in removing synthetic dyes from industrial effluents (Asana duct ml., 2005). This study investigates the ability of some selected Basidiomycete fungi to decolonize malachite green.
