The present study investigates the enrichment of anaerobic ammonium oxidation (anammox) bacteria in the marine environment using sediment samples obtained from a sea-based waste disposal site and discusses the construction of marine anammox bioreactor. Enrichment of bacteria related to Candidatus Scalindua wagneri along with simultaneous removal of nitrite and ammonium ions was observed in the continuous bioreactor culture under a total nitrogen loading rate of 0.4 kg-N m(-3) day(-1).
本研究利用从一个海上废物处理场采集的沉积物样本，对海洋环境中厌氧氨氧化（anammox）细菌的富集情况进行了调查，并讨论了海洋厌氧氨氧化生物反应器的构建。在总氮负荷率为0.4 kg-N m(-3) 天(-1) 的连续生物反应器培养中，观察到与“瓦氏拟斯卡林氏菌（Candidatus Scalindua wagneri）”相关的细菌富集，同时亚硝酸盐和铵离子被去除。
