MODIFIED THERMOPLASTIC STARCH FROM OPHIOSTOMA ULMI POLYSACCHARIDE CONVERSION

摘要

A novel modified thermoplastic starch is manufactured from a native starch using a polysaccharide produced by the fungus species Ophiostoma ulmi, by growing a culture in a yeast extract medium; adding the native starch; mixing, and harvesting the modified thermoplastic starch. The modified thermoplastic starch may be used in the manufacture of a biodegradable plastic which exhibits low water absorbency and high tensile strength. The plastic may be used to manufacture films or moulding products by casting, extrusion, injection, or compression techniques.
