Biological conversion pathways of sulfate reduction ammonium oxidation in anammox consortia

Zhen Bi, Deqing Wanyan, Xiang Li, Yong Huang

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 3, doi: 10.1007/s11783-019-1217-1

Abstract: Heterotrophic sulfate reduction mainly contributed to sulfate conversion.SRAO was considered an autotrophic process mediated by anammox bacteria, in which ammonium as electrondonor was oxidized by the electron acceptor sulfate.This process had been attributed to observed transformations of nitrogenous and sulfurous compounds inand final products of sulfate reduction.
