Welan gum is a microbial polysaccharide produced by a species of Alcaligenes and shows interesting rheological properties of use in the oil and agricultural industries. The structure is similar to gellan based on repeating glucose, rhamnose and glucuronic acid units but with a single side chain of either an alpha-L-rhamnopyranosyl or an alpha-L-mannopyranosyl unit linked (1,3) to the 4-O-substituted beta-D-glucopyranosyl unit in the backbone.
