Abstract The present study aims to determine the anaerobic ammonium oxidation (anammox) in the sediments samples from two eutrophic lakes (Lake Donghu and Lake Nanhu) in Wuhan, China by using nested PCR amplification, cloning, and sequencing. Anammox bacteria were reported from all sampling sites, which indicated that anammox bacteria widely exist in eutrophic lakes. However, nine out of ten sampling points showed presence of Candidatus Brocadia fulgida, indicating low diversity of anammox bacteria in eutrophic lakes. The dominance of Candidatus Brocadia fulgida further suggests its possible influence on nitrogen cycling in eutrophic water bodies.
