| Nitrogen Fixation and Nitrate Respiration by A zospirillum brasilense  | | | | Abstract
| Azospirillum The 0 2-sensitivitiy of N 2-fixation by the carotenoid forming strain Azospirillum brasilense Cd and the colourless strain Sp 7 is com pared in the present communication. As no difference in the reaction is observed with both strains, it is concluded that carotenoids do not protect nitrogenase from damage by 0 2. Azospirillum spp. have also been shown to perform N O '-dependent ^ -f i x ation. The physiological properties of this reaction are described in more detail in the present communication. Evidence is presented that NO^-dependent N 2-fixation is a transitory reaction, proceeding only as long as the enzymes o f assimilatory nitrate reduction are synthesized by the cells. | | | |
