  • Lactic acid bacterial suppressor mutants and their use as selective markers and as means of containment in lactic acid bacteria
    Patent number: 5866385
    Abstract: Methods of isolating nonsense suppressor-encoding lactic acid bacteria, cultures and compositions of lactic acid bacteria and plasmids comprising a gene coding for a nonsense suppressor, and a method of confining extrachromosomal replicons capable of replicating in lactic acid bacteria to lactic acid bacteria.
    Type: Grant
    Filed: December 5, 1995
    Date of Patent: February 2, 1999
    Assignee: CHR. Hansen A/S
    Inventors: Fran.cedilla.oise Dickely, Eric Johansen, Dan Nilsson, Egon Bech Hansen
  • Recombinant lactic acid bacterium containing an inserted promoter and method of constructing same
    Patent number: 5837509
    Abstract: A method of isolating a lactic acid bacterial DNA fragment comprising a promoter, the method comprising introducing a DNA molecule comprising a transposable element comprising a promoterless structural gene as a promoter probe gene into a population of a lactic acid bacterium, methods of constructing a recombinant lactic acid bacterium comprising a regulatable promoter by using the above method, a recombinant lactic acid bacterium comprising a gene coding for a desired gene product and operably linked thereto a regulatable lactic acid bacterial promoter not natively associated with the gene, the use of such a recombinant lactic acid bacterium and recombinant plasmids comprising a regulatable lactic acid bacterial promoter.
    Type: Grant

  • Lactic acid bacterial suppressor mutants and their use as selective markers and as means of containment in lactic acid bacteria
    Patent number: 5691185
    Abstract: Useful mutants of lactic acid bacteria or plasmids capable of replicating in lactic acid bacteria, comprising nonsense mutation suppressor-encoding genes, the use of such suppressor genes for confining a replicon to a specific lactic acid bacterium or to a lactic acid bacterium growing in a particular environment and for controlling the number of lactic acid bacterial cells in a particular environment.
