Abstract
The invention provides a system of heavy metal sequestration by bacteria. The bacteria expresses the ppk, mt, and/or β-galactosidase (lacZ) genes and can tolerate at least 25 μM mercury, 1,000 μM zinc, 250 μM cadmium, and 3,000 μM Pb. The system allows for facile determination of the presence of heavy metal contaminants in a liquid and the facile collection of the bacteria that has sequestered large amounts of heavy metal. Further provided is a system of gene expression in bacteria that comprises phage and plastid gene expression elements and delivers a particularly high level of protein expression and heavy metal resistance.
