CHROMIUM BIOSORPTION STUDIES ON A BACTERIAL ISOLATE

摘要

Heavy metals pose a grave concern in today's era owing to their serious toxic effects on flora and fauna. Prevalent usage of chromium compounds and their release without suitable treatment harms the food chain and has an adverse impact on ecosystem. Heavy metal tolerance and biosorption studies were conducted on a bacterial isolate. Maximum Tolerable Concentration (MTC) was found to be 100 mg/L. The rate of chromium reduction was maximum in log phase. Also pH optimization studies were done where maximum reduction was observed at pH 9.
