The anaerobic ammonium oxidation (anammox) process in paddy field and river sediment was measured using 15N stable isotope nitrogen. Furthermore, the quantification of Anammox bacterial and the relationship between anammox activity and denitrification activity were evaluated.The anammox activities were not detected in paddy field that applied high livestock wastewater with flooding water and alternative flooding and drainage. Conversely, anammox activity was detected in Yasuda paddy field that flooded through the year with drained water from an upland vegetable field. On the other hand, the anammox activity measured in the sediment samples from Koisegawa River was detected. However, the nitrogen removal by anammox process only accounted for less than 8% in Yasuda paddy field and less than3% of the total amount of removed nitrogen, which suggested that anammox process has limited contribution to nitrogen removal in fresh water environment. However, it is the first time that the phenomena of anammox process depended on denitrification was provedby experimental data in this study.

使用15N稳定同位素氮测量了稻田和河流沉积物中的厌氧氨氧化（anammox）过程。此外，还对厌氧氨氧化菌的定量以及厌氧氨氧化活性与反硝化活性之间的关系进行了评价。在高畜牧废水漫水和交替漫排排水的稻田中，未检测到厌氧氨氧化活性。相反，在安田稻田中检测到厌氧氨氧化活动，该稻田全年被旱地菜地的排水淹没。另一方面，在小伊势川的沉积物样品中检测到了厌氧氨氧化活性。然而，安田稻田厌氧氨氧化工艺的脱氮量仅占不到8%，占总脱氮量的不到3%，表明厌氧氨氧化工艺对淡水环境脱氮的贡献有限。然而，本研究首次用实验数据证明厌氧氨氧化过程依赖于反硝化作用的现象。
