Classification: CPC C  Y | IPC C

Claim 0:
1. An oxygen-generating bioelectrical reactor comprising:
a first abiotic oxidative chamber containing water;
a second biotic 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 first abiotic oxidative chamber and the second biotic reductive chamber providing a pathway for protons to move from the abiotic oxidative chamber to the biotic reductive chamber;
a counter electrode configured in the first abiotic oxidative chamber in contact with the water;
a working electrode and a reference electrode configured in the second biotic reductive chamber in contact with the aqueous mixture; and
a circuit electrically connecting the counter electrode, working electrode, and reference electrode such that the counter electrode is connected to the working electrode providing a pathway for electrons to move from the abiotic oxidative chamber to the biotic reductive chamber, wherein the circuit is configured to apply an electrical potential between the working electrode and the reference electrode.
