ABSTRACT:
An acid heteropolysaccharide P-318 which comprises galactose, galacturonic acid, N-acetylfucosamine and pyruvic acid in a ratio of about 2:3:1:1, a sulfated heteropolysaccharide P-318 having a 10% or less sulfur content which is prepared by sulfating said acid heteropolysaccharide and a process for preparing an acid heteropolysaccharide P-318 which comprises culturing Pseudomonas sp. 318 to produce the acid heteropolysaccharide P-318 and collecting the thus produced acid heteropolysaccharide P-318. The sulfated polysaccharide P-318 of the invention shows a strong antiviral activity in spite of a lower content of sulfate.
