Abstract
1331771 Acetylated mannuronic/guluronic polysaccharide TATE & LYLE Ltd 19 April 1971 [7 April 1970] 16375/70 Heading C3U [Also in Division C6] A polysaccharide consisting of partially acetylated variable block copolymer of 1,4- linked D-mannuronic and L-guluronic acid units is obtained by cultivating a microorganism of the species Azotobacter vinelandii under aerobic conditions in an aqueous nutrient medium containing one or more mono- or disaccharides as carbon source, and sources of Mo, Fe, PO 4 <SP>3-</SP>, Mg, K, Na, Ca and SO 4 = at a pH of 6À5-8À5 for at least the first half of the fermentation period and 4À5 to 8À5 for the remainder and then isolating the polysaccharide. Preferred strains of micro-organism are NCIB 9068, NCIB 8660 and NCIB 8789.
