摘要:
Variant xanthan gums, including non-acetylated, non-pyruvylated, non-acetylated and non-pyruvylated, and fully-acetylated xanthan gums. In addition, in vitro and in vivo methods for the synthesis of these gums are disclosed. Mutant Xanthomonas campestris strains useful in these synthesis are also specified.
摘要:
Compositions are provided which include a water-soluble polysaccharide polymer having a D-glucose:D-mannose:D-glucuronic acid ratio of about 2:2:1. 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. Processes for preparing the polysaccharide polymers are also provided.
