BACTERIUM HYDROLYZING POLYLACTIC ACID RESIN AND BACTERIUM HYDROLYSIS OF POLYLACTIC ACID RESIN

Japanese Patent JP3697639

B2

PURPOSE: To obtain the subject bacterium Amycolatopsis mediterranei (FERM P-14,921) having a polylactic acid resin hydrolyzing ability, useful for waste treatment of a polylactic acid resin useful as a material for medical treatment, a medicine, etc.
CONSTITUTION: This new bacterium Amycolatopsis mediterranei (FERM P-14,921) is an actinomyces belonging to the genus Amycolatopsi, having a polylactic acid resin hydrolyzing ability. In waste treatment of a polylactic acid resin having been used as a material for medical treatment and a medicine, an exhaust gas will not emit as incineration as an existing method, the treatment is carried out in a much shorter time than a reclamation treatment. By using the bacterium in composting facilities, a polylactic acid resin can be converted into a useful substance such as an organic acid, etc. The new bacterium is obtained by culturing a bacterium collected from water in soil, a river, a lake or a marsh at Tukuba City in Ibaragi Prefecture in a medium containing a polylactic acid resin, picking up a strain forming a transparent region in the periphery of a colony and carrying out isolation operation.
