Diauxic growth in Azotobacter vinelandii [PDF]

open access: yesJournal 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

Phospholipids of Azotobacter vinelandii [PDF]

open access: yesJournal 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.

Ultrastructure of Azotobacter vinelandii [PDF]

open access: yesJournal 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.

Multiple chromosomes of Azotobacter vinelandii [PDF]

open access: yesJournal 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.

Key factors affecting ammonium production by an Azotobacter vinelandii strain deregulated for biological nitrogen fixation

open access: yesMicrobial Cell Factories, 2020
The obligate aerobe Azotobacter vinelandii is a model organism for the study of biological nitrogen fixation (BNF). This bacterium regulates the process of BNF through the two component NifL and NifA system, where NifA acts as an activator, while NifL ...

Increases in alginate production and transcription levels of alginate lyase (alyA1) by control of the oxygen transfer rate in Azotobacter vinelandii cultures under diazotrophic conditions

open access: yesElectronic Journal of Biotechnology, 2021
Background: Alginates are polysaccharides used in a wide range of industrial applications, with their functional properties depending on their molecular weight. In this study, alginate production and the expression of genes involved in polymerization and
