  • Bacillus thuringiensis .delta.-endotoxin
    Patent number: 5932209
    Abstract: An improved Bacillus thuringiensis (B.t.) delta-endotoxin is created by the modification of the gene encoding the toxin. The toxicity of a B.t. toxin was improved by replacing the native protoxin segment with an alternate protoxin segment by constructing a chimeric toxin gene.
