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. … Web14 okt. 2015 · Photocatalytic N 2 fixation induced by NVs is free from the interference of other gases. The reason is that NVs could selectively adsorb and activate N 2 because NVs have the same shape and size as the nitrogen atom in N 2. In addition to this, NVs could also improve many other properties of g-C 3 N 4 to support photocatalytic N 2 fixation.

WebBiological nitrogen fixation is a process by which nitrogen is fixed in plants with the help of certain anaerobic bacteria. Biological nitrogen fixation was discovered by Dutch microbiologist Martinus Beijerinck in 1901. Only certain organisms like prokaryotes, such as bacteria and cyanobacteria, can fix atmospheric nitrogen.
