Molecular Characterization of Bacteria Isolated from E-waste Dumping Yards at Hyderabad, Telangana, India

Gayatri Y and Shailaja Raj M

Electronic waste or E-waste refers to electronic devices which are disposed into soil without being processed. These electronic goods are made of plenty of components which may contain toxic substances like heavy metals. Lead, one of the heavy metals present in many electronic goods gets accumulated in the soil and leaches into the surrounding environment if the goods are not processed properly. The metal is toxic at very low concentrations and may damage the flora and fauna. So the present study focuses on isolation and identification of bacteria from the samples collected from different E-waste dump yards located in Hyderabad, India. Based on cultural characterstics biochemical tests and the ability of the organisms to adsorb lead present in the soil contaminated with the metal, the organisms were identified as Bacillus licheniformis, Bacillus subtilis and Bacillus badius 16SrRNA sequencing studies confirmed the identified strain as Bacillus licheniformis with an accession no.
