Abstract: Disclosed is an enzyme, having the amino acid sequence of SEQ. ID. No. 1 with the activity of hydrolyzing dextran, starch, mutan, inulin and levan, a gene encoding the enzyme, and a transformed cell expressing the gene. Also disclosed is a method of producing an enzyme capable of degrading dextran, starch, mutan, inulin and levan, which comprises culturing the cell, expressing the enzyme in the cell and purifying the enzyme. A composition comprising the enzyme is provided for removing dextran or polysaccharide contaminants during sugar production. With such degradation activity, the enzyme not only finds various applications in the dental care industry, including anti-plaque compositions and mouthwashes, but is also useful in removing dextran or polysaccharide contaminants during sugar production.

Abstract: A diesel exhaust purification device for decreasing the amount of particulate matter and nitrogen oxides includes a Catalyzed Diesel Particulate Filter (CDPF) disposed in an exhaust conduit to capture particulate matter (PM). A differential pressure sensor detects the amount of PM contained in the CDPF. A post-injection injector is in the exhaust conduit. A Diesel Fuel Decomposition Catalyst (DFC) forms a reducing agent by decomposing the fuel injected from the post-injection injector. A nitrogen oxide adsorbing catalyst reduces nitrogen oxides accumulated therein and removes them using the reducing agent. A nitrogen oxide sensor in the exhaust conduit detects the amount of nitrogen oxides in exhaust gases. A control unit determines the regeneration time of the CDPF from signals detected by the differential pressure sensor, controls the amount of the fuel post-injected, determines the regeneration time of the nitrogen oxide adsorbing catalyst from signals detected by the nitrogen oxide sensor, controls the fuel post-injected through the post-injection injector.
