  • Method of limiting the survival of genetically engineered microorganisms in their environment
    Patent number: 6017730
    Abstract: The survival of cells is limited by introducing into the cells a regulatably expressible gene whose expression results in the formation of a cytoplasmatically active hydrolytic enzyme. Populations of cells containing, in addition to such a regulatably expressible gene, a DNA coding for an immunologically active, pesticidally active or environmental pollutant-degrading gene product, may be useful in immunologically active compositions, pesticidally active compositions and environmental pollutant-degrading compositions, respectively.
    Type: Grant
    Filed: May 4, 1998
    Date of Patent: January 25, 2000
    Assignee: GX BioSystems A/S
    Inventors: Soren Molin, Michael Givskov, Claus Sternberg Kristensen, Asim K. Bej, Leo Eberl
