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 ...

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 ...

Automatic Control for the Production of Alginate by Azotobacter Vinelandii
IEEE Access, 2019 Alginates are polymers used in the food and pharmaceutical industries as stabilizing, thickening, gel or film-forming agents. Food coatings formed from alginate have shown to have excellent properties such as flexibility and resistance to tearing.

Induction and ultrastructure for cysts of Azotobacter
浙江大学学报. 农业与生命科学版, 2001 Within 5 days of induction with n-butanol medium, 98%vegetative cells of Azotobacter vinelandii gave rise to cysts. 91% vegetative cells of Azotobacter chroococcus were converted to cysts. The cysts were spheroids or elliptical whose axe is 1.2 pm to 1.5

Morphogenesis of Cysts in Azotobacter vinelandii [PDF]
Journal of Bacteriology, 1970 Cultures of Azotobacter vinelandii were induced to encystment with β-hydroxybutyrate. The morphological events in the transition from cell to cyst were observed by electron microscopy of thin sections. Upon induction of encystment, cells became rounded and nonmotile.
