  • Recombinant bacillus thuringiensis strains, insecticidal compositions and method of use
    Patent number: 5776449
    Abstract: A transposable element, or transposon, isolated from Bacillus thuringiensis (B.t.) and designated as transposon Tn5401. The invention also includes a method of using this transposon in a site-specific recombination system for construction of recombinant B.t. strains that contain insecticidal B.t. toxin protein genes and that are free of DNA not native to B.t., insecticidal compositions containing recombinant B.t. strains and their use in insect control methods.
    Type: Grant
    Filed: September 20, 1996
    Date of Patent: July 7, 1998
    Assignee: Ecogen Inc.
    Inventor: James A. Baum
  • Recombinant Bacillus thuringiensis strain construction method
