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

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.

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 ...

Reduction of Nitrates by Azotobacter indicum and Azotobacter chroococcum Cultures
Applied Biochemistry and Microbiology, 2002The capacity for denitrification was studied in Azotobacter bacteria, which are free-living nitrogen-fixing obligatory aerobes. Data on nitrate reduction to nitrites and nitric oxide by A. indicum under anaerobic conditions were obtained for the first time for genus Azotobacter.

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.

Symbiosis of Azotobacter with Insects
Nature, 1946IN 1912, I published (Ber. d. bot. Ges.) a preliminary note on the constant symbiosis of Aphides with Azotobacter. The entomologist, Prof. K. Aulc, of Brno, had previously (1910) found that the hitherto mysterious function of an organ in aphides and similar insects, called the pseudovitellus, was a seat of symbiotic organisms.

Studies on Azotobacter. IV. Effect of Azotobacter Inoculation on Paddy
Madras Agricultural Journal, 1972Inoculation of crops with free living bacteria for increasing crop yields has been attempted by several investigators. Increased yields due to Azotobacter inoculation were obtained by Karunakar and Rajagopalan (1938) for sorghum, and Sundara Rao et al. (1963) for wheat.

Oxidative phosphorylation in Azotobacter vinelandii
Biochimica et Biophysica Acta, 1959Abstract 1. 1. An extract of Azotobacter vinelandii was fractionated and oxidative phosphorylation studied with a small-particle fraction. 2. 2. The phosphorylating system in the particles was inactivated by suspension in dilute salt solutions. This inactivation could be partly reversed by raising the salt concentration. Bivalent cations were
