Abstract

1411014 Heteropolysaccharide ex Etwinia tahitica KELCO CO 6 Nov 1973 51387/73 Heading C3U [Also in Division E1] The polysaccharide " Heteropolysaccharide- 10 " containing about 3% by weight of protein and about 97% by weight of carbohydrate, the carbohydrate portion of which contains about 19% by weight of a uronic acid, about 39% by weight of glucose, about 29% by weight of galactose and about 13% by weight of fucose, said heteropolysaccharide being compatible with Methylene Blue chloride dye, being substantially insoluble in dimethyl sulphoxide and soluble in water, having an acetyl content of about 4.5% and a specific rotation of [α] D = + 106 degrees (c 0.25, H 2 O) is obtained by cultivating under submerged aerobic conditions at 28-35‹C. a heteropolysaccharide producing strain of Erwinia tahitica in an aqueous nutrient medium containing as a source of carbon, hydrolysed starch of DE 20-35, a source of nitrogen, a source of magnesium and a source of phosphorus, until substantial viscosity has been imparted to said medium, and recovering said heteropolysaccharide -
