Biopolymer PS-87, a heteropolysaccharide comprising glucose, galactose, mannose, glucuronic acid and fucose, is pseudoplastic and has a consistency at 20°C of at least 150 poise and a yield stress value at 20°C of at least 30 dynes/cm 2 . Biopolymer PS-87 is synthesized by a specific strain or mutant of Bacillus polymyxa (NCIB 11429) or by micro-organisms which have undergone genetic manipulations. This heteropolysaccharide has many domestic and industrial applications as a suspending agent or thickener. |
