Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 69 words
Plasmid pCG 4 characterized in that it is isolated from the microorganism Corynebacterium glutamicum 225-250, ATCC 31830, in that it has a molecular weight of about 19 megadaltons, a number of cleavage sites for the restriction endonucleases, Eco Ri, Bam HI, Hind III, Pst I and Sal I of 4, 7, 9, 6 and 6, respectively, and in that it carries a gene for resistance to streptomycin and spectinomycin.
Claim 2
Dependent Claim 69 words
Plasmid pCG 4 characterized in that it is isolated from the microorganism Corynebacterium glutamicum 225-250, ATCC 31830, in that it has a molecular weight of about 19 megadaltons, a number of cleavage sites for the restriction endonucleases, Eco Ri, Bam HI, Hind III, Pst I and Sal I of 4, 7, 9, 6 and 6, respectively, and in that it carries a gene for resistance to streptomycin and spectinomycin.
Claim 3
Dependent Claim 27 words
A recombinant plasmid capable of autonomous replication in Corynebacterium or Brevibacterium constructed from plasmid pCG 4 according to claim 1 by adding a foreign DNA fragment thereto.
Claim 4
Dependent Claim 49 words
A recombinant plasmid capable of autonomous replication in Corynebacterium or Brevibacterium constructed from plasmid pCG 4 according to claim 1 by deleting a DNA region that does not affect its function to replicate autonomously and its resistance to streptomycin and spectinomycin and replacing it by a foreign DNA fragment.
Claim 5
Dependent Claim 45 words
A recombinant plasmid constructed from plasmid pCG 4 according to claim 1 by deleting a DNA region that does not affect its resistance to streptomycin and spectinomycin and replacing it by a foreign DNA region conferring a function to replicate autonomously in Corynebacterium or Brevibacterium.
Claim 6
Dependent Claim 30 words
A recombinant plasmid according to claim 4 which is plasmid pCG 11 (ATCC 39022) characterized by the restriction map illustrated in Figure 1 and a molecular weight of 4.5 megadaltons.
Claim 7
Dependent Claim 19 words
A recombinant plasmid constructed from plasmid pCG 11 according to claim 5 by adding a foreign DNA fragment thereto.
Claim 8
Dependent Claim 20 words
A biologically pure culture of the microorganism Corynebacterium glutamicum LA 103/pCG 11, ATCC 39022 which carries the plasmid pCG 11.
Claim 9
Dependent Claim 20 words
A biologically pure culture of the microorganism Corynebacterium glutamicum LA 103/pCG 11, ATCC 39022 which carries the plasmid pCG 11.
Claim 10
Dependent Claim 18 words
A biologically pure culture of the microorganism Corynebacterium glutamicum 225-250, ATCC 31830 which carries the plasmid pCG 4.
Claim 11
Dependent Claim 18 words
A biologically pure culture of the microorganism Corynebacterium glutamicum 225-250, ATCC 31830 which carries the plasmid pCG 4.
Claim 12
Dependent Claim 46 words
A biologically pure culture of a microorganism selected from the group consisting of Corynebacterium herculis ATCC 13868/pCG 4, Brevibacterium flavum ATCC 14067/pCG 4 and Brevibacterium lactofermentum ATCC 13655/pCG 4 having the identifying characteristics of ATCC 31837, 31838 and 31839, respectively, and carrying the plasmid pCG 4.
Claim 13
Dependent Claim 46 words
A biologically pure culture of a microorganism selected from the group consisting of Corynebacterium herculis ATCC 13868/pCG 4, Brevibacterium flavum ATCC 14067/pCG 4 and Brevibacterium lactofermentum ATCC 13655/pCG 4 having the identifying characteristics of ATCC 31837, 31838 and 31839, respectively, and carrying the plasmid pCG 4.
