Abstract
Water-soluble polysaccharide polymers are provided including a polymer composed of repeating pentamer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:2:1, and a polymer composed of repeating tetramer units having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:1:1. The D-glucose moieties are linked in a beta-�1,4! configuration. The inner D-mannose moieties are linked in an alpha-�1,3! configuration, generally to alternate glucose moieties. The D-glucuronic acid moieties are linked in a beta-�1,2! configuration to the inner mannose moieties. The outer mannose moieties are linked to the glucuronic acid moieties in a beta-�1,4! configuration. Also an isolated acetylase deficient mutant of Xanthomonas is used in a process to produce the polysaccharide.
