Glucan polysaccharide

摘要

A glucan which is characterized by repeating units of [3)-Glc-(1->4)-Glc-(1->4)-Glc-(1->] wherein Glc represents alpha-D-glucopyranose residue. This glucan may be prepared by cultivating a microorganism of the genus Elsinoe capable of producing this glucan on a nutrient medium to produce this glucan and separating and recovering this glucan. This glucan may be used, for example, in the form of a film for packaging film material.
