The replication origin of Azotobacter vinelandii

Molecular and General Genetics MGG, 2000
The putative replication origin of Azotobacter vinelandii was cloned as an autonomously replicating fragment after ligation to an antibiotic resistance cartridge. The resulting plasmids could be isolated and labelled by Southern hybridisation with the antibiotic resistance cartridge as probe and also visualised by electron microscopy.

The vanadium nitrogenase of Azotobacter

Polyhedron, 1989
The properties of the recently characterized vanadium-dependent nitrogenase system of Azotobacter are reviewed and compared with the better characterized Mo-nitrogenases. Vanadium is present in V-nitrogenase in a vanadium- and iron-containing protein (VFe protein), analogous in structure and function to the MoFe protein of Mo-nitrogenase.

Electron transport in Azotobacter vinelandii

Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966
Summary 1. The nature and intracellular distribution of the respiratory enzyme system of Azotobacter vinelandii has been investigated. 2. Whole cells of this organism were found to contain high concentrations of ubiquinone (Q-8) but, in contrast to Azotobacter vinelandii strain O, no menaquinone (vitamin K2) was detected. 3.

Nutritive Qualities of Azotobacter vinelandii

Journal of the American Dietetic Association, 1957
The bodies of the bacteria called Azotobacter, when dried, contain 75 per cent protein of good quality. Growing this organism on a commercial scale could conceivably add substantially to the world's supply of protein ...

Vanadium nitrogenase of Azotobacter

1990
Vanadium-containing nitrogenases have been purified and characterised from Azotobacter chroococcum and Azotobacter vinelandii, the structional genes cloned, sequenced and assigned to the polypeptides of the enzyme. In this synthesis paper on V-nitrogenase we review material published since the International Nitrogen Fixation Congress in Cologne in 1988

Aspects of Genetics of Azotobacters

1984
There have been a number of studies on the genetics of N2-fixation in Azotobacter. Early reports describe the isolation and biochemical characterization of several classes of mutants defective in N2-fixation or normal regulation of the genes (nif) responsible (Wyss, Wyss 1950; Green et al, 1953; Fisher, Brill 1969; Sorger, Trofimenkof, 1970; Shah et al,

NOTES ON THE BIOLOGY OF AZOTOBACTER

Proceedings of the Society for Applied Bacteriology, 1951
Summary:Forty strains of A. chroococcum from Danish soils showed a rather uniform power of nitrogen fixation in mannitol solution where the mean gain of nitrogen after 12 days corresponded to 17.1 mg./g. of mannitol, with a standard deviation of ±9.1%.
