RESUMO
A soil isolate produced a novel extracellular polysaccharide (EPS) with unusually potent thickening powers. The EPS contained d-mannose, d-glucose, d-galactose, and d-glucuronic acid in the unique molar ratio 1:4:1:2 and 10 to 15% acetate. Viscosities of a 1-g/liter aqueous solution were 1 × 106 and 14 × 103 cP at shear rates of 0.01 and 0.1 s-1, respectively. The EPS was insensitive to high concentrations of NaCl and CaCl2.
