Biodegradation of malachite green by wild mushroom of Chhatisgrah

Abstract

The release of dye in to environment is of great concerned due to color, toxicity, mutagenicity species and carcinogenicity of the dye, considerable attention has been given in evaluating the capability of microorganism in decolourisation and biosportion of dye. In this study we take seven wild mushroom cultures Pleurotus florida, Pleurotus sajorkaju, Grifola frondosa, Polyporous sp. 1, Jelly sp., Schizophylum commune, Polyporous sp. used for decolourisation and degradation of  dye, on further screening of decolorizing seven mushroom cultures transferred over potato dextrose agar medium  containing 0.01% malachite green (MG) dye. A plate assay was performed for the detection of decolorizing ability of mushroom clearing zone (decolorization) was formed surrounding the mushroom cultures. Decolorization was confirmed by UV-VIS spectrophotometer and studied at wavelength 540 nm. After 5 days percentage of dye degradation by Jelly sp. (98.25%), Schizophyllum commune (64.25%), Polyporous sp.2 (26.25%), and after 10 days the same species gives the percentage of dye degradation i.e. 99.75%, 97.5%, 68.5% respectively. But out of these three species Jelly sp. give the high percentage (after 5 days 98.25% and after 10 days 99.75%) of dye degradation.
