Abstract
Biological decolorisation of Cibacron Black W-NN, was comparatively studied using five commercial (Pleurotus djamor, P. ostreatus, P. citrinopileatus, P. eryngiiand P. sajor-caju) and three wild types of (Pleurotus ostreatus, P. ostreatus and P. eryngii) white rot fungi strains on agar plates. The initial dye concentrations in the medium were 20, 50, 100, 200 and 500 mg/L, respectively. All P. ostreatus strains and P. sajor-caju fully decolorized Cibacron Black W-NN without any problem. Other organisms were found to be negatively affected from increasing dye concentrations and were able to decolorize the dye used up to a certain concentration (50 mg/L for P. citrinopileatus; 100 mg/L for commercial P. eryngiiand 200 mg/L for wild P. eryngii).
Key words: Agar plate screening, biological decolorisation, Pleurotus spp., textile dye
