Abstract Fixation of dissolved dinitrogen in culture solutions by the photosynthetic bacterium Rhodopseudomonas capsulata, strain B10, reduced the lag phase associated with growth with glutamate. A comparable effect was not observed with ammonium chloride. This strain assimilated nitrate but nitrogen fixation was depressed during early growth on nitrate. It is shown that nitrite, the first product of nitrate assimilation, inhibits nitrogen fixation during the early stages of cell growth.
