A METHOD FOR PRODUCING BIODEGRADABLE RESINS

摘要

A METHOD FOR PRODUCING BIODEGRADABLE RESINS COMPRISES THE STEPS OF CULTURING POLYHYDROXYALKANOATE (PHA)-PRODUCING MICROORGANISMS IN A CULTURE MEDIUM CONTAINING VEGETABLE OIL AND/OR ANIMAL FAT AS CARBON SOURCE FOR A DURATION OF 24 TO 96 HOURS; HARVESTING THE CULTURED PHA-PRODUCING MICROORGANISMS FROM THE CULTURE MEDIUM CHARACTERIZED IN THAT LYOPHILIZING THE HARVESTED PHA-PRODUCING MICROORGANISMS TO FORM DRIED CELL MASS; PULVERIZING THE DRIED CELL MASS TO A PREDETERMINED SIZE FORMING RESINS POWDER.
