Abstract

In the past 30 years many aspects of biological nitrogen fixation have been studied intensively by many different workers. These studies have included: the agents of fixation, the physiology of fixation, inhibitors of fixation, and cell free nitrogen fixation and symbiont relationships during fixation. Ten years ago workers in the field postulated the nitrogenase system was adaptive in nature. This was the result of several workers finding it necessary to add a small amount of fixed nitrogen to their cultures before they would fix atmospheric nitrogen. Thus far the only work that has been done on the inductive phenomenon of the nitrogenase system has been by other workers in this laboratory. Results from recent study in this laboratory of the effects of nitrogen supplements on nitrogen fixation suggest that amino acid supplement and the free amino acid pool play a significant role in the formation of the nitrogen fixing enzymes.
