一(B.t)生物测定的研究概况 苏云金杆菌(B.t)现已成为大规模商品生产的细菌杀虫剂。七十年代以来,发展尤为迅速,T.L.couch在总结美国近十年B.t研究的进展时指出:制定用国际单位(In)表达B.t制剂效价的生物测定法是决定美国B.t研究取得突破性进展的一个重要因素。
Research Overview of B.t. Bioassays Bacillus thuringiensis (B.t.) is now a bacterial pesticide for large-scale commercial production. Since the 1970’s, the development has been particularly rapid. TLcouch summarized the progress of the Bt study in the United States during the past decade and pointed out: The development of a bioassay to express the potency of Bt preparations in International Units (In) is a breakthrough in the Bt study in the United States An important factor.
