The size of the chromosome of Azotobacter chroococcum [PDF]

Microbiology (United Kingdom), 1994
The DNA of Azotobacter chroococcum M4 was digested with rare-cutter restriction endonucleases Asel and Dral and restriction fragments were separated by pulsed-field gel electrophoresis. The chromosome size was estimated to be around 5300 kb by summing the sizes of the resolved restriction fragments.

Production of Cyanocobalamine by Azotobacter chroococcum

Zentralblatt für Mikrobiologie, 1984
A strain of Azotobacter chroococcum was found to produce a considerable amount of cyanocobalamine especially when cultivated in a medium enriched with 0.3% ammonium chloride. Maximal production of the vitamin was achieved after six days of incubation in static cultures. The organism required molybdenum, iron (Fe++), cobalt and ascorbic acid for optimal

Studies on Azotobacter chroococcum

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1981
Summary Seeds of wheat, maize and cotton were inoculated with different strains of A. chroococcum . The performance of the strains was evaluated by conducting sowing experiments with and without basal dressing of fertilizer. Homologous selection of a pigmented strain which established better on roots of that particular crop has shown increase in ...

Nitrite uptake in Azotobacter chroococcum

Archives of Microbiology, 1992
Nitrite uptake is made up of two components in Azotobacter chroococcum, a passive diffusion, presumably of nitrous acid, and an active transport of nitrite which uses the nitrate transport system. Only the active component is under regulatory control.

Utilization of aromatic substances by Azotobacter chroococcum

Research in Microbiology, 1990
Azotobacter chroococcum utilized catechol, protocatechuic acid and gentisic acid as sole carbon source. Rothera's test indicated the ortho cleavage of phenols. The cells displayed high levels of dioxygenase activity. Catechol was cleaved by the ortho pathway mediated by catechol 1,2-dioxygenase.

Sensitivity of Azotobacter Chroococcum to some Antibiotics

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1973
Summary Low numbers of Azotobacter , and failure of the response of crops to inoculation with organism have been attributed to inhibition by many rhizosphere organisms, like actinomycetes and bacteria which produce toxic substances, including some known antibiotics (Krasil'nikov 1954). Inhibition of Azotobacter chroococcum by penicillin was noted

Carbon Dots Enhance the Nitrogen Fixation Activity of Azotobacter Chroococcum

ACS Applied Materials & Interfaces, 2018
Biological nitrogen fixation is critical for the nitrogen cycle on the earth. Nitrogen-fixing bacteria, as an environmentally friendly microorganism, convert atmospheric nitrogen to available nitrogen source for plants.
