ABSTRACT:
A polysaccharide polymer is disclosed which is a better viscosifier of water than xanthan gum. The polysaccharide polymer and its non-acetylated form, are comprised of glucose and mannose moieties in a ratio of about 2:1. The invention also discloses Xanthomonas mutants which produce the polysaccharide polymer but which do not produce xanthan gum. Methods of preparing the polysaccharide polymers and of their use are also described.
