On Carbohydrate Consumption by Azotobacter chroococcum
Annals of the Missouri Botanical Garden, 1920In a previous paper (Allen, '19) devoted mainly to the study of the cause of beneficial action resulting from mechanical agitation of Azotobacter solution cultures, the defects of existing experimental methods for the study of the physiology of this organism were pointed out.

The ultrastructure of vegetative cells and cysts of Azotobacter chroococcum
Archiv f�r Mikrobiologie, 1962The ultrastructure of vegetative cells and cysts of Azotobacter chroococcum shows that these two morphological forms are distinctly different. The cyst is surrounded by a multi-layered envelope consisting of the following structural elements: an irregularly outlined exocystorium and a cyst coat made up of an outer dense and an inner less dense layer ...

The hydrogen cycle in nitrogen-fixing Azotobacter chroococcum
Biochimie, 1978H2 will support nitrogenase activity (C2H2 reduction) in Azotobacter chroococcum with or without added carbon substrate. Results show that H2 is metabolised to transfer electrons to nitrogenase and to the respiratory chain to produce ATP. H2-supported nitrogenase activity is most significant at low carbon substrate concentrations, but also occurs at ...

Associative symbiosis of Azotobacter chroococcum and higher plants
Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1979The association between a selected strain of Azotobacter chroococcum and seven plants was investigated in water cultures under sterile conditions. Azotobacter population progressively increased in the nutrient solution and on the rhizoplane. Microbial propagation depends on the type of plant, being much higher in presence of wheat, followed by barley ...

Some properties of purified nitrogenase of Azotobacter chroococcum
Biochimica et Biophysica Acta (BBA) - Enzymology, 1969Abstract The nitrogenase of Azotobacter chroococcum was fractionated into two essential components by anaerobic chromatography and elution with MgCl2. Fraction 1, which contained iron and molybdenum, was not damaged by exposure to air for 30 min at 20° but Fraciton 2, which also contained iron but only traces of molybdenum, was completed inactivated ...

Utilization of Chloroaromatic Substances by Azotobacter chroococcum
Systematic and Applied Microbiology, 1990Summary Azotobacter chroococcum strain MSB1 exhibited catabolic versatility in utilizing several chloroaromatic compounds as sole carbon source. Phenoxyacetic acid, p- and o-chlorophenoxyacetic acids, 2,4-D and p- and o-chlorophenols were utilized as carbon substrate. The strain efficiently dechlorinated 2,4-D.

[Reduction of nitrates by cultures of Azotobacter indicum and Azotobacter chroococcum ].
Prikladnaia biokhimiia i mikrobiologiia, 2003The capacity for denitrification was studied in Azotobacter bacteria, which are free-living nitrogen-fixing obligatory aerobes. Data on the nitrate reduction to nitrites and nitric oxide by A. indicum under anaerobic conditions were obtained for the first time for genus Azotobacter.
