Publication number: 20130023016Abstract: The present invention relates to a polynucleotide that is active to an acetyl glutamate synthase and acetyl ornithinase which are associated with ornithine or arginine biosynthesis from Corynebacterium glutamicum. The present invention also relates to a polypeptide encoded by said polynucleotide, a recombinant vector comprising said polynucleotide, to a transformant obtained by introducing said recombinant vector to a host microorganism for producing L-ornithine or L-arginine, and transforming the recombinant vector, and to a method for producing L-ornithine or L-arginine by culturing said transformant.

Patent number: 7485450Abstract: The present invention provide a microorganism comprising an inactivated chromosomal tdcBC gene and an inactivated chromosomal pckA gene, which has remarkably improved productivity of L-threonine. Also, the present invention provides a method of producing L-threonine using the microorganism. The microorganism is prepared by incorporating by a recombination technique an antibiotic resistance gene into a pckA gene on the chromosome of a bacterial strain containing an L-threonine degradation-associated operon gene, tdcBC, which is inactivated. The microorganism has the effect of preventing degradation and intracellular influx of L-threonine due to the inactivation of the tdcBC operon gene, and includes more activated pathways for L-threonine biosynthesis. Therefore, the microorganism is useful for mass production of L-threonine because of being capable of producing L-threonine in high levels and high yields even in the presence of high concentrations of glucose.Type: GrantFiled: April 2, 2004Date of Patent: February 3, 2009Assignee: CJ Cheiljedang CorporationInventors: Young Hoon Park, Byoung Choon Lee, Dae Cheol Kim, Jin Ho Lee, Jae Yong Cho

Patent number: 7378267Abstract: A method for producing L-threonine using a microorganism is provided. In the method, the threonine dehydratase (tdc) gene existing in the genomic DNA of the microorganism is partially deactivated using a recombination technique. For a microorganism strain with enhanced activity of threonine operon-containing enzymes and the phosphoenolpyruvate carboxylase (ppc) gene, the tdc gene engaged in one of the four threonine metabolic pathways is specifically deactivated, thereby markedly increasing the yield of L-threonine.Type: GrantFiled: May 16, 2002Date of Patent: May 27, 2008Assignee: Cheil Jedang CorporationInventors: Jae Yong Park, Byoung Choon Lee, Dae Cheol Kim, Jin Ho Lee, Jae Yong Cho, Young Hoon Park

Publication number: 20050018376Abstract: An electrostatic chuck (ESC) for a wafer which directs a cooling gas to predetermined cooling areas of the wafer mounted on the chuck. Ring type sealing members divide the mounted wafer into the predetermined cooling areas and the predetermined cooling areas are independently supplied with a helium cooling gas. Each of the predetermined cooling areas is supplied through a separate conduit system wherein each conduit system has a single inlet into the chuck and a plurality of outlets which emit the helium gas into a respective one of the predetermined cooling areas. The plurality of outlets for each predetermined cooling area may communicate with the inlet via a respective plurality of branch conduits or via one or more branch conduits and a peripheral conduit which connects the plurality of outlets. By independently controlling the predetermined cooling areas, temperature variations on the wafer are effectively controlled.Type: ApplicationFiled: April 9, 2004Publication date: January 27, 2005Applicant: Samsung Electronics Co., Ltd.Inventors: Jong-rok Park, Jae-yong Cho, Byeong-sun An
