<p>The invention relates to Proteobacteria that show unusually high level resistance to a wide range of metal oxides and oxyanions and to methods using selected Proteobacteria subgroups for efficient reduction of certain metal oxides and oxyanions to the free metal. High level resistance was shown to be affected by growth conditions, and was observed in facultative photoheterotrophs such as Rhodobacter sphaeroides grown either chemoheterotrophically or photoheterotrophically. The disclosed methods are adaptable to the production of hydrogen from cultures of Peoteobacteria grown in the presence of tellurite class oxyanions with carbon dioxide and nitrogen as carbon and nitrogen sources. The methods have commercial application for efficient bioremediation of carbon dioxide and nitrogen.</p> |
