Transformation and Precipitation of Toxic Metals by 'Pseudomonas maltophilia'
Abstract
The aims of this research are to study each of the various molecular mechanisms whereby toxic metal cations and oxyanions are chemically transformed by Pseudomonas maltophilia strain OR-02. The research effort for the current year has focused on the microbial-dependent transformations of mercury, selenium, tellurium, chromium and lead. The NADPH-dependent reduction of Hg(II) was catalyzed by an inducible mercuric reductase. The reduction of selenite and tellurite to their insoluble elemental forms was mediated by an intracellular glutathione reductase that utilized the spontaneously-formed bis(gluthathio) Se(II) or bis(gluthathio)Te(II), respectively, as pseudosubstrates.
