Abstract: In various embodiments of the present disclosure, an oxygen-generating bioelectrical reactor comprises two chambers, a first oxidative chamber configured for the abiotic oxidation of water to generate molecular oxygen, and a second reductive chamber configured for the biotic reduction of an insoluble metal(loid) oxide or hydroxide. In various embodiments, the biotic reduction comprises microbially-catalyzed metal(loid) ion reduction of the insoluble metal(loid) oxide or hydroxide, wherein a dissimilatory metal(loid) reducing microorganism transfers electrons obtained from the oxidation of the water extracellularly to the metal(loid) ions.
