| Abstract: | The nitrogenase and nitrate reductase activities of the molybdenum(Mo)-requiring parent Nostoc muscorum and its tungsten (W)-and chromium (Cr)-requiring mutant strains, growing with Mo,W and Cr, respectively, were significantly enhanced by the additionof 0.063 µM vanadium (V). Such interactions were not observedwith NO2- as a nitrogen source. (Received October 17, 1983; Accepted May 2, 1984) |
