Escherichia coli expressing thiosulfate reductase genes (phsABC) from Salmonella typhimurium is able to remove significant amounts of heavy metals from the medium within 24 h: 99% of zinc up to 500 microM, 99% of lead up to 200 microM, 99% of 100 icroM and 91% of 200 icroM cadmium. In a mixture of 100 microM each of cadmium, lead, and zinc, the strain removes 99% of the total metals from solution within 10 h. Cadmium is removed first, lead second, and zinc last |
