TY - DATA T1 - Data underlying the publication: Oxygen-to-Ammonium-Nitrogen Ratio as an Indicator for Oxygen Supply Management in Microoxic Bioanodic Ammonium Oxidation PY - 2024/06/28 AU - Xiaofang Yan UR - DO - 10.4121/8dbd9669-632e-49b7-826f-2473c1bb7270.v1 KW - Bioanodes KW - Ammonium oxidation KW - Oxygen supply KW - Nitrogen selectivity KW - Nitrogen functional microorganisms N2 - <p><strong></strong>In this study, we systematically investigated NH<sub>4</sub><sup>+</sup> oxidation at the bioanode with different O<sub>2</sub> and NH<sub>4</sub><sup>+</sup>-N<sup> </sup>ratios (O₂/NH₄⁺-N) of 0.5, 1.0 and 1.5. 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> ER -
