FAMILY OF XANTHAN-BASED POLYSACCHARIDE POLYMERS INCLUDING NON-ACETYLATEDAND/OR NON-PYRUVYLATED GUM AND ACETYLATED OR NON-ACETYLATED POLYTETRAMERGUM

摘要

Variant xanthan gums are disclosed, including non-acetylated, non-pyruvylated, non-acetylated and non-pyruvylated, and fully-acetylated xanthan gums and other gums which are structurally-related to xanthan gum such as acetylated polytetramer and non-acetylated polytetramer. In addition, in vitro and in vivo methods for the synthesis of these gums are disclosed. Mutant X. campestris strains useful in these syntheses are also specified.
