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

Ultrastructure of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1970 Vegetative cells and cysts of Azotobacter vinelandii 12837 were prepared for electron microscopy by several methods assumed to preserve structural details destroyed by techniques previously reported in the literature.

Phospholipids of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1969 Analyses of resting cells of Azotobacter vinelandii revealed that numerous phospholipids were present that did not concentrate in the membranous R 3 fraction which carried out electron transport function.

Survival of Azotobacter and other microbial group in dry soil by storage
Journal of the Selva Andina Research Society, 2022 In dry soils, the survival of the genus and species of Azotobacter is parallel to that of other native microbial groups such as actinomycetes and fungi of that environment, depending on the genetic adaptation capacity of each one, in combination with ...

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

Respiration in Azotobacter vinelandii and its relationship with the synthesis of biopolymers
Electronic Journal of Biotechnology, 2020 Azotobacter vinelandii is a gram-negative soil bacterium that produces two biopolymers of biotechnological interest, alginate and poly(3-hydroxybutyrate), and it has been widely studied because of its capability to fix nitrogen even in the presence of ...

Journal of the Selva Andina Research Society, 2021 The health growth of Triticum aestivum (wheat) requires the application of nitrogen fertilizer (NF). One way to optimize the dose of NF in T. aestivum is to inoculate its seed with Azotobacter vinelandii and Bacillus subtilis, genus and species of ...

Multiple chromosomes of Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1989 The number of copies of the genes leuB, nifH, nifD, and nifK per cell of Azotobacter vinelandii has been determined to be about 80. A beta-lactamase gene was integrated into the A. vinelandii chromosome by single-point crossover. Subsequently, we have been able to detect nearly 80 copies of this beta-lactamase gene per cell of A.
