title: Effect of uranyl and molybdate ions on microbial fixation of nitrogen.
abstract: The addition of molybdate in presence of uranyl acetate causes a considerable increase in nitrogen fixation in all the species of nitrogen-fixing Azotobacter, studied in this paper, as compared to the case in which these ions are taken separately (4, 3).
