ABSTRACT:
A novel heteropolysaccharide S-184 is disclosed. The compound is a gum produced under suitable conditions by the novel microorganism Alcaligenes sp. This new heteropolysaccharide is composed primarily of carbohydrate as uronic acid (7% to 16%) and mannose, glucose, and galactose in the molar ratio of 1:3:5. The non-carbohydrate portion contains 12-16% protein and 3-4.5% acyl groups. The compound is used to alter viscosity and rheology of aqueous solutions.
