ACIDIC HETEROPOLYSACCHARIDE, SULFATED POLYSACCHARIDE, AND PRODUCTION THEREOF

摘要

PURPOSE:To provide a sulfated polysaccharide useful as an antiviral agent by utilizing a microorganism. CONSTITUTION:An acidic heteropolysaccharide P-318 characterized by including galactose, galactoronic acid, N-acetylfucosamine and pyruvic acid in a composing ratio of approximately 2:3:1:1. A sulfated polysaccharide P-318 having a sulfur content of <=10% and obtained by sulfating the acidic heteropolysaccharide. A method for producing the acidic heteropolysaccharide P-318 characterized by culturing Pseudomonas.SP-318 and subsequently recovering the produced and accumulated acidic heteropolysaccharide P-318. And Pseudomonas.SP-318.
