Bacillus sp. Doosan 3 for producing polysaccharide (I) is screened from soil in the medium contg. 40-50% of saccharide. The screened strain is cultured in the medium contg. sucrose, polypeptone, yeast extract, KH2PO4, MgSO4, and NaCl at 36C for 2-3 days and the (I) is extracted from the cultured medium by general method of solvent precipitation at 52.9% of yield. (I) have a forming film and adhesiveactivity.
