Two new Bacillus thuringiensis strains, which are deposited at the DSM under accession nos. 5131 and 5132, produce crystal proteins during sporulation that are toxic to Coleoptera. The crystal proteins contain 74 kDa and 129 kDa protoxins, respectively, which can yield 67 and 66 kDa toxins, respectively, as trypsin-digestion products. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that codes for its respective toxin, is resistant to Coleoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Coleoptera.
两种新的苏云金芽孢杆菌菌株(存于 DSM,登录号分别为 5131 和 5132)在孢子化过程中会产生对鞘翅目昆虫有毒的晶体蛋白。晶体蛋白分别含有 74 kDa 和 129 kDa 的原毒素,作为胰蛋白酶消化产物,可分别产生 67 kDa 和 66 kDa 的毒素。植物的基因组经 DNA 序列转化后,对鞘翅目昆虫具有抗性。每种菌株本身或其晶体、晶体蛋白、原毒素或毒素都可用作防治鞘翅目昆虫的杀虫组合物的活性成分。
