Mycoremediation of tannery effluent using spent bags of edible mushroom Calocybe indica


SAM Kamalasankari, S Karpagam

Bioremediation of tannery effluent using spent bags of milky mushroom mycelium Calocybe indica was undertaken to effectively utilize the discarded bags after harvesting the edible mushroom. Mycelium grown in rice straw was used for effluent treatment. The rate of bioremediation was enhanced by adding co-metabolites like carbon, nitrogen, phosphorous source in the form of carbon as glucose and sucrose; nitrogen as urea and ammonium chloride; phosphorus as ortho phosphoric acid. After treatment, effluents were analysed by spectrophotometer. Bioassay of treated effluents were done by germinating green gram seeds; to study the suitability of the effluent for irrigation and to find out the toxic effect of the treated effluent on seed germination. For the bioassay shoot and root length of germinated green grams were measured. The result, prove that the addition of nitrogen and phosphorous source enhance myremediation of tannery effluent. Using Milky Mushroom mycelium to treat the tannery effluent proves to be an efficient and ecofriendly venture.
