Nanocarboxylates of molybdenum and of iron enhance the functional activity of Rhizobium radiobacter 204

This paper covers the study of molybdenum and iron nanocarboxylates’ effect on the functional activity of Rhizobium radiobacter 204. The data obtained have shown that the nanocarboxylates of molybdenum and of iron have improved the nitrogenase activity of the studied bacteria in pure culture in concentrations exceeding 0.3–0.5 mg/dm 3 . The introduction of metal nanoparticles to the technology of R. radiobacter 204 cultivation has revealed their joint positive influence on the nitrogenase enzyme activity in rhizosphere of winter wheat plants, on crop photosynthesis via the chlorophyll biosynthesis and on crop productivity.
