Abstract: An aspartic protease and the use of the aspartic protease in the hydrolysis of gluten. This protease can hydrolyze gluten and the gluten-derived immunogenic peptides at pH 2.0˜4.0. Also provided are methods for the production of the aspartic protease, including recombinant plasmids, transformants, and a purification method thereof; methods of using the aspartic protease to prepare drugs and oral enzyme supplements for treatment of diseases or discomforts related to gluten ingestion, such as celiac disease; and a method of using the asparic protease in food-processing process to remove or reduce gluten in foods or beverages.

Abstract: The invention discloses a fumigant composition for pest control comprising a chemical compound represented by formula (I) or/and a pesticidally acceptable reagent. By administering an effective amount of the fumigant composition for pest control disclosed in the invention into a closed space is capable of effectively killing a variety of pests, and will not have a considerable health impact on human and harm to the environment; given an appropriate operation is taken.
