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.

Provided are a recombinant Ralstonia eutropha capable of producing polylactate or a hydroxyalkanoate-lactate copolymer, and a method of preparing polylactate or a hydroxyalkanoate-lactate copolymer using the same. The recombinant Ralstonia eutropha, which is prepared by introducing a gene of an enzyme converting lactate into lactyl-CoA and a gene of a polyhydroxyalkanoate (PHA) synthase using lactyl-CoA as a substrate thereto, may be cultured, thereby efficiently preparing a lactate polymer and a lactate copolymer.

摘要:
The present invention relates to a reservoir tank for an automobile, which is provided with a height-adjustable sub filler neck so as to be retracted when not in use and extracted when filling coolant, whereby the reservoir tank can be disposed low in the automobile. The reservoir tank forming a cooling module together with a condenser, a radiator and a fan and shroud assembly is disposed at a carrier, and includes a filler neck for filling coolant and a cap for closing the filler neck, and is communicated with a radiator so as to control an amount of the coolant in the radiator, wherein the reservoir tank is integrally formed with a shroud of the fan and the shroud assembly, and the filler neck is formed with a sub filler neck which is retracted into and extracted from the filler neck.
