摘要： Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E.coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E.coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.

摘要： 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.

摘要： Provided is a method of preparing polylactate (PLA) or a copolymer thereof using a mutant microorganism in which a gene participating in a coenzyme A (CoA) donor- and lactate-producing pathway is genetically manipulated to increase the productivity of a CoA donor and lactate. Amounts of the CoA donor and the lactate are simultaneously increased in a microbial metabolic pathway to enable effective biosynthesis of PLA and a hydroxyalkanoate-lactate copolymer having a high content of lactate, which is industrially useful.
