Decolourization of synthetic dyes using rice straw attached Pleurotus ostreatus

摘要

Preliminary studies were conducted to assess the degree of decolourization of different dyes such as Malachite green,Indigo carmine,Xylidine ponceau,Bismark brown,Congo red and Methyl orange using the white rot fungus Pleurotus ostreatus.The effect of initial concentration of different dyes on the decolourization was studied.The effect of pH and biomass concentration during decolourization were also observed for all the dyes.The time course of decolourization was also characterised for all the dyes at their optimum concentrations.An improved percent decolourization [95%] was achieved for Xylidine ponceau,Methyl orange,Congo red and Bismark brown with the rice straw attached Pleurotus ostreatus.
