Polysaccharide, applications thereof, fermentation process to obtain the same and pseudomonas strain producing it

摘要

This polysaccharide consists of repeat units which contain a skeleton comprising 2 radicals of d-mannose, 2 of d-glucose, 1 of d-galactose, 1 of d-glucuronic acid, 1 of d-xylose, 1 of l-lyxose and 1 of l-fucose, on which pyruvic acid radicals can be grafted and in which some of the saccharide hydroxyl groups are esterified in the acetate form. It can be employed as a viscosity modifier, thickener and gelling agent.
