Abstract
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 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.
