Abstract
A method for producing mixed metal oxide compounds includes the steps of: providing a supply of a metal reducing bacteria; providing a culture medium suitable for growth of the bacteria; providing a first mixed metal oxide phase comprising at least a first and a second metal, at least one of the first and second metal being reducible from a higher to a lower oxidation state by the bacteria; and, combining the bacteria, the culture medium, the first mixed metal oxide, and at least one electron donor in a reactor, wherein the bacteria reduces at least one of the first metal and the second metal from the higher to the lower oxidation state to form a second mixed metal oxide phase.
