The production and characterization of alginate produced by Pseudomonas syringae.

摘要

Alginate has many industrial uses because of its unique colloidal behavior, and its ability to thicken, stabilize, emulsify, suspend, form films, and produce gels. Currently, all commercial alginate comes from brown algae, where it exists naturally as a structural material. Many different types of brown algae produce alginate but it can only be obtained in sufficient quantity and quality from a limited number of species. On the basis of location, at least half of the world's resources of this polymer are potentially at risk due either to political instability or industrial pollution. Bacteria provide a potentially unlimited alternate source for alginate. Pseudomonas syringae pv phaseolicola ATCC 19304, produced an acetylated alginate-like polysaccharide with a weight average molecular weight (M
