Our specific focus was on achieving high NH<sub>4</sub><sup>+</sup> oxidation while simultaneously maintaining the selectivity of NH<sub>4</sub><sup>+</sup> oxidation to N<sub>2</sub>. Additionally, the diversity of N-related functional bacteria was characterized to elucidate the underlying N conversion reactions in the MEC systems. This study elucidates the influence of microoxic levels of O2 on NH4+ oxidation at bioanodes and providing insights for process optimization. </p> %I 4TU.ResearchData
