20100222545 | COPOLYMER COMPRISING 4-HYDROXYBUTYRATE UNIT AND LACTATE UNIT AND ITS MANUFACTURING METHOD - The present invention relates to a copolymer comprising 4-hydroxybutyrate monomer unit and lactate monomer unit, a copolymer 4-hydroxybutyrate monomer unit, lactate monomer unit and 3-hydroxyalkanoate, or their preparing method. More specifically, the present invention relates to a method for preparing a copolymer comprising lactate monomer; 4-hydroxybutyrate monomer; and optionally 3-hydroxyalkanoate, wherein the method comprises culturing a cell or plant comprising the gene of enzyme converting lactate and 3-hydroxyalkanoate into lactyl-CoA and 3-hydroxyalkanoyl-CoA, respectively, phosphotransbutylase gene, butyrate kinase gene and polyhydroxyalkanoate synthase gene together, and the copolymer made by the method. The copolymer of the present invention is a biodegradable polymer being able to be usefully used instead of conventional synthetic plastic, and the copolymer can be used for medical use. | 09-02-2010 |
20100330634 | Mutants Having Capability To Produce 1, 4-Butanediol And Method For Preparing 1, 4-Butanediol Using The Same - A mutant capable of producing 1,4-butanediol and a method of preparing 1,4-butanediol using the same are provided. The mutant microorganism is prepared by introducing and amplifying genes encoding enzymes converting succinate into 4-hydroxybutyrate and 4-hydroxybutyrate into 1,4-butanediol in a microorganism capable of producing succinate. The method includes culturing the mutant in a medium containing carbohydrate and obtaining 1,4-butanediol from the culture. Thus, 1,4-butanediol, which is essential in chemical industry, can be prepared in a biological process. | 12-30-2010 |
20110046339 | COPOLYMER CONTAINING 3-HYDROXYALKANOATE UNIT AND LACTATE UNIT, AND ITS MANUFACTURING METHOD - The present invention relates to a copolymer comprising 3-hydroxyalkanoate monomer unit and lactate monomer unit, or their preparing method. More specifically, the present invention relates to a method for preparing a copolymer comprising lactate monomer and 3-hydroxyalkanoate monomer, wherein the method comprises culturing a cell or plant comprising the gene of enzyme converting lactate and 3-hydroxyalkanoate into lactyl-CoA and 3-hydroxyalkanoyl-CoA, respectively, and polyhydroxyalkanoate synthase gene together, and the copolymer made by the method. The copolymer of the present invention is a biodegradable polymer being able to be usefully used instead of conventional synthetic plastic, and the copolymer can be used also for medical use. | 02-24-2011 |
20130302875 | NOVEL USE OF LIPOLYTIC ENZYME FOR FORMATION OF ANTI-FINGERPRINT COATING, METHOD OF FORMING ANTI-FINGERPRINT COATING, SUBSTRATE COMPRISING THE ANTI-FINGERPRINT COATING FORMED BY THE METHOD, AND PRODUCT COMPRISING THE SUBSTRATE - Provided are a novel use of a lipolytic enzyme for forming anti-fingerprint coating, a method of forming anti-fingerprint coating including treating a substrate with a composition comprising the lipolytic enzyme, a substrate including the anti-fingerprint coating formed by the same method, and a product including the same. The anti-fingerprint coating can reduce contamination of display devices, appearances of electronic devices or building materials by fingerpris. | 11-14-2013 |
20130309745 | POROUS STRUCTURE FOR FORMING AN ANTI-FINGERPRINT COATING, METHOD FOR FORMING AN ANTI-FINGERPRINT COATING USING THE POROUS STRUCTURE, SUBSTRATE COMPRISING THE ANTI-FINGER-PRINT COATING FORMED BY THE METHOD, AND PRODUCTS COMPRISING THE SUBSTRATE - Provided are a porous structure for forming anti-fingerprint coating capable of providing a self-cleaning function to a surface of a substrate, a method of forming anti-fingerprint coating using the same, an anti-fingerprint coated substrate prepared by the same method, and a product including the same. When the porous structure including a lipolytic enzyme is formed on the surface of the substrate, contaminants decomposed by an enzyme are absorbed into a pore, and thus anti-fingerprint coating may be more effectively performed to remove detectable contamination from a surface of the substrate. As a result, contamination by fingerprints on the surface of a display device, the appearance of an electronic device, or building materials can be effectively reduced. | 11-21-2013 |
20140242650 | Recominant Ralstonia Eutropha Capable of Producing Polyactic and Acid or Polylatic Acid Polymer, and Method for Producing Polyactic Acid or Polylatic Acid Copolymer Using the Same - Provided are a recombinant | 08-28-2014 |
