  • Bacterial phytochelatin synthetase
    Publication number: 20050136426
    Abstract: The present invention relates to the discovery of a gene in a bacterium expressing a protein that has an activity similar to plant phytochelatin synthetase. This gene was discovered in the marine ?-proteobacterium Microbulbifer degradans strain 2-40, and is cloned and expressed in the bacterium Escherichia coli. Bacteria expressing this gene are useful in remediation of contaminated solids and liquids and in the extraction of rare and/or valuable metals.
