In batch cultures of Azotobacter vinelandii exposed to air and ultraviolet‐irradiated nitrogen, an increases in nitrogen fixation, compared to that of cultures exposed to air and non‐irradiated nitrogen, has been noted. This supports the hypothesis that an ionized nitrogen molecule is important for the biological nitrogen fixation.
