Abstract
A galactomannan heteropolysaccharide is prepared by fermentation of a previously unknown microorganism, named Erwinia sp. ATCC No. 55046. The polysaccharide has valuable properties as a thickening, suspending, stabilizing and lubricating agent in aqueous systems. It has a chemical composition of mannose, galactose and galacturonic acid in the approximate molar ratio of 5:3:2. The polysaccharide can be produced in high yield and volumetric productivity from a submerged culture fermentation of a low-cost, lactose-containing whey or whey permeate medium.
