Induction nitrogen fixation
WebThe effect of nitrogen on excretion and metabolism of glycolate in Anabaena cylindrica (CCAP 1403/2a) was studied. Glycidate, an inhibitor of glutamate:glyoxylate aminotransferase (EC 2.6.1.4), reduced the L-methionine-DL-sulfoximine-induced NH 4 + release by ca 40%, while net CO 2 fixation and C 2 H 2 reduction were not lowered. … Web10 apr. 2024 · Nitrogen fixation and denitrification activities of the community of CWD decomposers. Unlike the CO 2 emission, the maximum nitrogen fixation activity was observable at an earlier decay stage, stage II; however, the largest amount of biomass of the microorganisms responding to the applied readily decomposable substrate (glucose) …
