Alginate Production by Azotobacter Vinelandii
Abstract
Although all commercial alginates are today of algal origin, there is interest in the production of alginate-like polymers from bacteria. The species Azotobacter vinelandii seems to be the best candidate for the industrial production of alginate molecules characterized by a chemical composition, molecular mass and molecular mass distribution suited to a well defined application, especially required in the biotechnological, biomedical and pharmaceutical fields. The production of alginate by A. vinelandii has been to date widely investigated both in batch (mainly in the shaken flask scale) and in continuous cultures. This article summarizes current knowledge on the structure and properties of alginates and their applications and presents an overview of up-dated research on the physiology, genetics and kinetics of the production of alginate by Azotobacter vinelandii and its rheology, including the results of our recent studies.

Bacterial-derived alginates, such as those produced by Pseudomonas aeruginosa and Azotobacter vinelandii, typically have higher M-block content, resulting in softer, more elastic gels that degrade quickly and may lack sufficient mechanical strength for long-term barrier use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
