Abstract excerpt
Xanthan gum is an extracellular heteropolysaccharide produced by the bacterium Xanthomonas campestris. Xanthan has wide commercial application as a viscosifier of aqueous solutions. Previously, through genetic engineering, a set of mutants defective in the xanthan biosynthetic pathway has been obtained. Certain mutants were shown to synthesize and polymerize structural variants of the xanthan repeating unit and...
