Nutritive Qualities of Azotobacter vinelandii
Journal of the American Dietetic Association, 1957The 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 ...

Acid Production by Azotobacter vinelandii
Nature, 1963Azotobacter vinelandii has been characterized by its lack of acid production in culture1. In fact, most species of Azotobacter do not form acid, but appear to oxidize carbohydrates completely to carbon dioxide and water2. The notable exceptions to this are the acid-tolerant A. indicum (Beijerinckia indica)3 and A. macrocytogenes4 that are characterized

Azotobacter vinelandii Citrate Synthase
Biochemistry, 1995We have purified the citrate synthase from Azotobacter vinelandii and have determined that the size of the subunit is 48,000 Da and the structure of the holoenzyme is a hexamer. This contrasts with earlier estimates that indicate a 58,000 Da subunit and a tetrameric structure.

Electron transport in Azotobacter vinelandii
Biochimica et Biophysica Acta (BBA) - Enzymology and Biological Oxidation, 1966Summary 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.

The replication origin of Azotobacter vinelandii
Molecular and General Genetics MGG, 2000The 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.

Tn 10 mutagenesis in Azotobacter vinelandii [PDF]
Molecular and General Genetics MGG, 1987 The tetracycline-resistant transposon Tn10 and its "high-hopper" derivative Tn10HH104 were introduced into the Azotobacter vinelandii genome using suicide conjugative plasmids derived from pRK2013. Several types of mutants induced by either of these elements are described.

Inhibition of Azotobacter vinelandii rhodanese by NO-donors
Biochemical and Biophysical Research Communications, 2003Nitric oxide (NO) is a versatile regulatory molecule that affects enzymatic activity through chemical modification of reactive amino acid residues (e.g., Cys and Tyr) and by binding to metal centers. In the present study, the inhibitory effect of the NO-donors S-nitroso-glutathione (GSNO), (+/-)E-4-ethyl-2-[E-hydroxyimino]-5-nitro-3-hexenamide (NOR-3),

The cytochrome system of Azotobacter vinelandii
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 19671. Difference spectra and carbon monoxide action spectra of Azotobacter vinelandii small particles indicate the presence of cytochromes c4 + c5, b1, a1, a2 and o, of which a1, a2 and possibly o may be acting as terminal oxidases. 2. The aerobic steady-state reduction of cytochrome b1 was unexpectedly found to be much lower than that of cytochromes ...

Silicate in the Metabolism of Azotobacter vinelandii
Nature, 1958MOLYBDENUM complexed as silico-molybdate has been shown to be very active in the re-activation of aldehyde oxidase from which the molybdenum has been removed by dialysis1. Other reports have implicated silicate, phosphate and other anions as agents which increase the activity of molybdate -dependent enzymes2,3.

Glucose catabolism in Azotobacter vinelandii
Archives of Biochemistry and Biophysics, 1964Abstract The catabolism of glucose in proliferating cells of Azotobacter vinelandii has been examined with respect to the nature and participation of individual pathways. The radiorespirometric method and substrate incorporation studies were used in this investigation.
