在灭虫微生物中,苏云金杆菌很有名气,人们最早认识它是在德国的面粉厂里。苏云金杆菌能产生多种对昆虫有致病作用的毒素,利用苏云金杆菌制备的农药也已经用了半个多世纪。近期科学家发现,利用转基因技术把苏云金杆菌的抗虫基因转移到农作物体内,让农作物自己制造农药也是可行的。 In the pest control microorganisms, Bacillus thuringiensis is famous, people first recognized it in the flour mill in Germany. Bacillus thuringiensis can produce a variety of toxins that have pathogenic effects on insects, and pesticides prepared using Bacillus thuringiensis have also been used for more than half a century. Recently, scientists found that the use of transgenic technology to Bacillus thuringiensis insect-resistant genes transferred to crops, so that crops themselves to produce pesticides is feasible.
