Abstract

PURPOSE: A novel polysaccharide useful as thickeners, excipients, gelling agents, emulsion stabilizers, sizing agents, etc., containing glucose, mannose and mannuronic acid at a specified ratio, being acetylated and having a MW in a specified range.
CONSTITUTION: A polysaccharide which consists of glucose, mannose and mannuronic acid in a mol ratio of 1:0.4W0.7:4W17, which is acetylated at an acetylation degree of about 0.1W1.0 and which has a MW of 103W105 as measured by a 3,5-dinitrosalicylic acid method. Said polysaccharide can be prepared by culturing bacteria which produce this polysaccharide belonging to genus Azotobacter, e.g., Azotobacter vinelangi IFO: 12018, at about 25W30°C for 72W120hr under an aerobic condition in an aqueous culture medium while passing a stream of nitrogen and/or nitrogen-containing gas, precipitating the produced polysaccharide from the filtrate and purifying the polysaccharide.
