  • Plasmid
    Patent number: 4778762
    Abstract: A substantially pure plasmid which is characterized by a molecular weight of 3.0.+-.0.1 megadalton and the restriction endonuclease-cleavage map shown in the Figure. This plasmid is capable of propagating in Corynebacteria and due to its size is useful as a vector for the cloning of exogenous genes.
    Type: Grant
    Filed: October 18, 1982
    Date of Patent: October 18, 1988
    Assignee: Ajinomoto Company Incorporated
    Inventors: Kiyoshi Miwa, Mahito Terabe, Takayasu Tsuchida, Masaaki Ishida, Shigeru Nakamori, Konosuke Sano, Haruo Momose
  • Method for producing L-lysine by fermentation
    Patent number: 4560654
    Abstract: An L-lysine producing microorganism which is constructed by incorporation into a recipient strain of the genus Brevibacterium or Corynebacterium of a hybrid plasmid having inserted therein a DNA fragment which is derived from a donor strain of the genus Brevibacterium or Corynebacterium and which controls resistance to S-(2-aminoethyl)-cysteine and productivity of L-lysine, is useful for the production of high levels of L-lysine by fermentation.
    Type: Grant
    Filed: May 7, 1981
    Date of Patent: December 24, 1985
    Assignee: Ajinomoto Company Incorporated
    Inventors: Kiyoshi Miwa, Mahito Terabe, Masaaki Ishida, Hiroshi Matsui, Haruo Momose
  • Composite plasmid
    Patent number: 4514502
    Abstract: A composite plasmid which comprises (A) a drive-unit region derived from a plasmid a capable of propagating in a Coryneform glutamic acid-producing bacterium, and (B) a gene fragment derived from a plasmid b capable of propagating in Escherichia coli or Bacillus subtilis and having at least a region expressing drug resistance.
    Type: Grant
    Filed: June 10, 1982
    Date of Patent: April 30, 1985
    Assignee: Ajinomoto Co., Inc.

  • Method for producing L-arginine by fermentation
    Patent number: 4430430
    Abstract: An L-arginine producing microorganism which is constructed by transforming into a recipient strain of the genus Escherichia of a vector having inserted therein an arg A gene derived from a chromosomal DNA of the genus Escherichia, is useful for the production of high levels of L-arginine by fermentation.
