摘要：
The isolation, cloning of an enhancin gene bel1 from Bacillus thuringiensis, and the use of an enhancin Bel1 in biological insecticides are disclosed in the present invention. A new enhancin gene bel1 is isolated from Bacillus thuringiensis subsp. kurstaki YBT-1520, and its encoded product is a new enhancin Bel1. The enhancin has very strong effect-enhancing activity on the insecticidal action of insecticidal crystal protein Cry1Ac in killing Lepidoptera insects. The insecticidal activity of genetically engineered Bacillus thuringiensis BMB0187 developed on the basis of this enhancin is 5.7 times as high as that of the initial strain.
