PURPOSE:To provide the subject polysaccharide useful as low calorie dietary fibers for foods, drugs, cosmetics, etc., by culturing a polysaccharide A-1845- producing bacterium belonging to the Streptomyces and subsequently collecting the product from the cultured solution. CONSTITUTION:A polysaccharide A-1845-producing bacterium belong to the Strepomyces [e.g. Streptomyces Sp-A-1854(FERM 12043)] is cultured, and the resultant polysaccharide A-1846 is collected from the cultured product. The polysaccharide A-1845 is white, has hexose, uronic acid, pentose, methylpentose, amino sugar and phosphorus as constituents, has mannose, galactose, galactwronic acid, xylose, rhamnose, glucose, fucose, and ribose as constituting saccharides, is soluble in water, is insoluble in methanol, ethanol, phopanol and acetone, is positive to an anothrone reaction, negative to a ninhydrin reaction, is acidic, does not accept the action of amylase, and has a specific rotation power [alpha]D<24> of +57.0 deg.. |
