Claim 10:
11. An oxygen-generating bioelectrical reactor comprising:
an oxidative chamber containing water;
a reductive chamber containing an aqueous mixture of dissimilatory metal(loid)-reducing microorganisms and a water-insoluble metal(loid) oxide or hydroxide capable of microbially-catalyzed reduction by the dissimilatory metal(loid)-reducing microorganisms;
a proton-selective membrane, disposed between the oxidative chamber and the reductive chamber, for providing a pathway for protons to move from the water in the oxidative chamber to the aqueous mixture in the reductive chamber;
a counter electrode coupled to the oxidative chamber and in contact with the water;
a working electrode coupled to the reductive chamber and in contact with the aqueous mixture;
a reference electrode coupled to the reductive chamber and in contact with the aqueous mixture; and
a circuit electrically connecting the counter electrode, the working electrode, and the reference electrode such that the counter electrode is connected to the working electrode to provide a pathway for electrons to move from the oxidative chamber to the reductive chamber, the circuit being configured to apply an electrical potential between the working electrode and the reference electrode.
