Nitrite Inhibition of Bacterial Dinitrogen Fixation

Dinitrogen fixation by crude extracts from Rhodopseudomonas palustris and Rhodomicrobium vannielii and by purified nitrogenase preparations from Azotobacter vinelandii and Clostridium pasteurianum is inhibited by nitrite, whereas in the same preparations nitrate is without effect. In Clostridium nitrite seems to interact with dinitrogenase reductase component of the bacterial nitrogenase complex.
