| Research Abstract |
The influences of dissolved organic matter (DOM) on denitrifying activity were researched with the sediment of Lake Kasumigaura. To examine the molecular weight of DOM on denitrification, the additions of organic compounds with different molecular weight to denitrifying activity were carried out. As a result, denitrification would not necessarily depend on the molecular weight of DOM. Moreover, to examine the mean bond enthalpy of DOM on denitrification, the organic compounds with different mean bond enthalpy but almost similar molecular weight (ca. 100) were added to denitrifying activity. As a result, denitrifying activity and the mean bond enthalpy of DOM did not have the correlation. Future studies are necessary to clarify the interaction of denitrification and DOM.
