Role of membrane potential in ammonium inhibition of nitrogenase activity in the cultured cyanobiont Nostoc ANTH

S. Singh, B. B. Singh, P. S. Bisen

Research output: Contribution to journalArticle


Ammonium at 5m M completely inhibited nitrogenase activity of Nostoc ANTH but only slightly inhibited the membrane potential, indicating that these two events are independent and that nitrogenase activity is not regulated by the latter.
