Detection of Heavy Metals Indifferent Soil Samples and Their Bioremediation with the Help of Fungus Cunninghamella sp

Abstract

Due to increased population, industrialization and urbanization are environmental contamination is growing day by day. Levels of some heavy metals (Zn, Pb and Cd) were investigated in various soil samples, nursery sample (NS), nursery sample containing herbicides (HS) and a sample from the area that has less human interference (LHI), after bioremediation with the help of fungus. There are various fungi (Aspergillus sp., Cunninghamella sp., Trichoderma sp. and Candida sp.) which can be used for the removal of different heavy metals. Fungus has very low nutritional value and high versatility and their biomass can be easily subjected to chemical and physical treatment. Toxicity of these heavy metals can lead to various diseases on the basis of their acute and chronic experience. Biosorption experiments were initially conducted with the isolation and identification of fungi Cunning lamellas on the SDA media. For the treatment of untreated soil wet fungal biomass is prepared, filtered and added in the soil samples. Quantity of soil samples (500 g, 100 g, 10 g) were distributed on the basis of temperature; room temperature and outside temperature and incubated for 15 days for bioremediation. Heavy metals were detected with the help of atomic absorption spectrophotometer and readings were taken at the interval of 7 days and 15 days after digestion of soil samples.
