Role of enzymatic system of screened pleurots ostreatus ibl-02 in the bio-removal of synthetic dyes effluent

White rot fungi have exclusive capacity to decolorize synthetic azo dyes. five different fungal strains namely s. commune ibl-01 (sc), p. ostreatus ibl-02 (po) p. chrysosporium ibl-03 (pc), t. versicolor ibl-04 (tv) and g. lucidum ibl-05 (gl) were used for the decolorization of synthetic dyes effluent. p. ostreatus ibl-02 showed maximum decolorization of synthetic textile effluent, so it was selected for the optimization of experimental factors. different physico-chemical parameters were optimized using pleutorus ostreatus ibl-02 (po), for the maximum de-colorization of synthetic dyes effluent. under optimum conditions, p. ostreatusibl-02 (po) decolorized the synthetic dyes effluent by 92.7%. effect of various amendments like carbon and nitrogen sources on the decolorization and mineralization of synthetic dyes effluent by pleutorus ostreatus ibl-02 was also studied. ligninolytic enzymes at the end of each experiment were studied to find their role in decolorization and mineralization of synthetic dyes effluent. uv-visible spectral analysis was used to indicate the decolourization of treated dyes effluent sample. a diminution in spectral line height displaying absorption maxima designated decolorization (%) while a move of spectral line to the uv-region depicted the degradation of synthetic dyes effluent.
