| Outline of Final Research Achievements |
Anammox is the important process not only for wastewater treatments but also for the removal of excess nitrogen from the natural environment. It is necessary to use isotopic fractionation factor during anammox to determine the relative contribution of anammox in the total nitrogen removal in the natural ecosystem, but only one report exists on this factor. We determined nitrogen and oxygen isotopic fractionation factors during anammox, which were totally different from the ones for denitrification. We now prepare the manuscript for the submission to the international scientific journals to publish this new finding.
