Plasmids of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1988 Four laboratory strains and two isolates of Azotobacter vinelandii were found to contain plasmids. Twenty-five laboratory strains which could fix nitrogen did not have free, covalently closed circular plasmid DNA. The plasmids varied in size from 9 to 52 megadaltons, and each strain yielded only one plasmid. No discernible differences in ability to fix

The Siderophore Metabolome of Azotobacter vinelandii [PDF]
Applied and Environmental Microbiology, 2016 ABSTRACT In this study, we performed a detailed characterization of the siderophore metabolome, or “chelome,” of the agriculturally important and widely studied model organism Azotobacter vinelandii . Using a new high-resolution liquid chromatography-mass spectrometry (LC-MS) approach, we found over 35 ...

Efficiency of Azotobacter, on Growth of Wheat Plants and Its some Anatomical Characteristics [PDF]
Journal of Agricultural Chemistry and Biotechnology, 2023 Azotobacter chroococcum and Azotobacter vinelandii were isolated and purified from soil samples collected in El-Gharbia, (Qutor), Governorate. These Azotobacter isolates produced the hormones cytokinin, gibberellins and auxin.

Diauxic growth in Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1985 Azotobacter vinelandii exhibited diauxie when grown in a medium containing both acetate and glucose as carbon sources. Acetate was used as the primary carbon source during the acetate-glucose diauxie. Uptake of acetate was constitutively expressed during both diauxic phases of growth. Induction of the glucose uptake system was inhibited in the presence
