Potential of Spent Bags of Milky Mushroom Calocybe Indica in Bioaccumulation of Heavy Metals from Tannery Effluent

In Present study, Biosorption of heavy metals by spent bags of milky mushroom mycelium along with paddy straw were used for effluent treatment. To enhance the treatment effect, co-metabolites like Carbon Source (Glucose, Sucrose), Nitrogen Source (Ammonium Chloride, Urea), and Phosphorous Source (Orthophosphoric acid) were added. After treatment with fungal mycelium, the effluent were analysed by UV - Visible Spectrophotometer to determine the growth and Atomic Absorption Spectrophotometer for biosorption of heavy metals by the fungal mycelium and treated effluent. The toxicity of treated effluent was studied by germinating green gram seeds, the root and shoot lengths were measured and seedling index vigour were calculated. Bioaccumulations of heavy metals were comparatively high in presence of glucose and phosphorous as co-metabolites sources as observed from Atomic Absorption Spectrophotometer analysis.
