N2-Fixation by chemoautotrophic hydrogen bacteria

Archives of Microbiology, 1974
The Gram-positive coryneform bacteria strains 14g and 7C were found to be able to grow with N2 as sole nitrogen source when incubated under microaerobic conditions. Nitrogenase activity in whole cells was assayed by acetylene reduction. High rates of ethylene production (50–120 nmole/hxmg cell protein) were observed in N2 or glutamate grown cell ...

Physiology and Biochemistry of N2-fixation by Cyanobacteria

1984
Aspects of the subject have recently been reviewed by several authors (Stanier, Cohen-Bazire 1977; Haselkorn 1978; Stewart 1980; Hawkesford et al. 1983; Wolk 1982; Bothe et al. 1980; Bothe 1982; Neuer et al. 1983). Therefore newer findings, published in the last two years, will preferentially be discussed in the present communication.

Breeding Legumes for Improved N2-Fixation

1984
The earth’s atmosphere is approximately 78% nitrogen in elemental (N2) form. Although nitrogen is required by plant and animal life for synthesis of protein and other essential molecules this gaseous form is unavailable to eukaryotic organisms. In general, plants require ammonia (NH2) or nitrate (NO3 -) sources of nitrogen as a major nutrient. Animals,

Photosynthate Limitation of Symbiotic N2 Fixation

1981
For the past several years our laboratory has studied various aspects of the energetics of nitrogen fixation, experiments leading to the conclusion that there is a high metabolic energy cost for this process (1). Several of these experiments will be discussed below (see Figs. 1 and 4 for integration of this work).
