Decolourization of synthetic textile dyes using the edible mushroom fungi Pleurotus.
The ability of three Pleurotus species (P. florida LCJ 65, P. ostreatus LCJ 183 and P. sajorcaju LCJ 184) was compared for the decolourization of bromophenol blue, brilliant green and methylred using by solid and liquid medium. All three Pleurotus species were effective in decolourizing the dyes on potato dextrose agar plate. During quantitative decolourization experiments, the absorption spectrum of the dye solution showed a steady decrease in decolourization with the increase in the days of incubation. The decolourization efficiency varied for species to species and it was found that P. sajorcaju LCJ 184 effectively decolourized the selected dyes by 85-98%. In present study, different factors (dye concentration, inoculums size, pH, static and shaking culture conditions) influencing the ability of Pleurotus species to decolourize three different dyes is documented and the result proposes P. florida LCJ 65 and P. sajorcaju LCJ 184 as potential strains for decolourization ofbromophenol blue, brilliant green and methylred dye.
