The extensive exploitation and usage of lead resources have caused serious environmental pollution problems currently. Bioremediation of Pb2 +contaminated water and soil environments using microbes is regarded as a promising technology due to the advantages of its cost-effective, easy operation and environmental- friendly properties. In order to understand Pb2 +biosorption characterization of microbes, an indigenous lead- resistant bacterium- Arthrobacter sp. 12- 1(Gen Bank No. KM362724) was isolated from l...
