β-Ketothiolase genes in Azotobacter vinelandii
Gene, 2000Azotobacter vinelandii is proposed to contain a single beta-ketothiolase activity participating in the formation of acetoacetyl-CoA, a precursor for poly-beta-hydroxybutyrate (PHB) synthesis, and in beta-oxidation (Manchak, J., Page, W.J., 1994. Control of polyhydroxyalkanoate synthesis in Azotobacter vinelandii strain UWD.

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.

Aggregates of Azotobacter vinelandii cysts
Canadian Journal of Microbiology, 1972Cysts of Azotobacter vinelandii which were examined by transmission and scanning electron microscopy appear to be connected to each other by a common, continuous layer of extra-exinic material. This connecting material is easily destroyed and normally not visualized by commonly used techniques.

Dimerization of Azotobacter vinelandii flavodoxin (azotoflavin)
Archives of Biochemistry and Biophysics, 1975Abstract Molecular weight determinations by gel filtration of Azotobacter vinelandii flavodoxin (azotoflavin) which had been stored aerobically for various periods of time indicated that this flavoprotein electron carrier could exist in the monomeric ( M r = 23,000) or dimeric ( M r = 46,000) form.

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 ...

Respiratory control in Azotobacter vinelandii membranes
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract 1. Significant respiratory control was observed with partly coupled respiratory membranes of Azotobacter vinelandii only when an energy conservation site was coincident with a rate-limiting step in electron transfer. This criterion was satisfied with NADH alone (Site I), NADH plus malate (Site II) but not with malate alone.

The terminal oxidases of Azotobacter vinelandii
Biochemical and Biophysical Research Communications, 1973Abstract The terminal respiratory chain of the aerobic nitrogen-fixing bacterium Azotobacter vinelandii was investigated by photochemical action spectra. Terminal cytochrome oxidases a 2 , a 1 and o were confirmed as being the terminal oxidases for the physiological substrates NADH and L-malate.

ПЕРСПЕКТИВИ ЗАСТОСУВАННЯ AZOTOBACTER VINELANDII
Біотехнологія XXI століття, 2022Після відкриття у 1903 році бактерія Azotobacter vinelandii була прийнята у якості модельного організму для дослідження процесів фіксації азоту, аеробного дихання, фізіології мікроорганізмів, продукції та асиміляції водню, кінетики ферментів, зокрема вивчення структури і механізмів нітрогеназ. Цьому сприяли основні характеристики роду Azotobacter:

Alginate Production byAzotobacter Vinelandii
Critical Reviews in Biotechnology, 1997Although all commercial alginates are today of algal origin, there is interest in the production of alginate-like polymers from bacteria. The species Azotobacter vinelandii seems to be the best candidate for the industrial production of alginate molecules characterized by a chemical composition, molecular mass and molecular mass distribution suited to ...
