Nitrate permease from Azotobacter chroococcum
Physiologia Plantarum, 1993Active transport systems in bacteria can be divided into two groups: those that are osmotic shock‐resistant with one single membrane protein, and those that are shock‐sensitive and have a membrane‐bound protein complex plus a soluble periplasmic protein.

Occurrence of Multiple Antibiotic Resistance in Azotobacter chroococcum
Zentralblatt für Mikrobiologie, 1989Of 117 strains of Azotobacter chroococcum, isolated from local soils the antibiotic resistance pattern to ten widely used antibiotics was determined by antibiotic disk and agar plate dilution method. Over 95% of the strains were resistant to 10 micrograms ml-1 concentration of ampicillin, chloramphenicol, erythromycin and tetracycline and 70% or more ...

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 ...

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 ...

[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.
