Protein profiles of crystal delta-endotoxins were determined in twenty nine Bacillus thuringiensis strains-soil and phylloplane isolates--from Poland. Electrophoretic analysis revealed quantatively and qualitatively different patterns of delta-endotoxin crystal preparations of these B. thuringiensis strains. The crystalline parasporal inclusions of B. thuringiensis isolates were composed of two, three, four or five proteins. Molecular weights of these polypeptides varied from 23.4 kDa to 142 kDa. There is lack of correlation between serovars of B. thuringiensis strains, the morphology of crystals and the number and size of proteins in parasporal inclusions.
对来自波兰的29株苏云金芽孢杆菌菌株（土壤和叶平面分离株）的晶体δ-内毒素蛋白质谱进行了测定。电泳分析揭示了这些苏云金芽孢杆菌菌株δ-内毒素晶体制剂在数量和质量上的不同模式。苏云金芽孢杆菌分离株的晶体伴孢晶体由两种、三种、四种或五种蛋白质组成。这些多肽的分子量在23.4 kDa至142 kDa之间变化。苏云金芽孢杆菌菌株的血清型、晶体形态以及伴孢晶体内蛋白质的数量和大小之间缺乏相关性。
