【摘要】 短小芽孢杆菌（Bacillus pumilus）噬菌体PP5在碱性蛋白酶生产菌珠B.pumilus 289中能进行普遍性转导。PP5对于B.pumilus 289的营养标记的转导频率为10^-6转导子/PFU。对于B.pumilus 1037和B.pumilus 289之间的链霉素抗性标记的转导频率为10^-4至10^-7转导子/PFU。从而建立了一个新的B.pumilus遗传转导系统。更多还原

【Abstract】 Bacteriophage PP5 isolated from soil was able to mediate generalized transduction in Bacillus pumilus 289.The transduction frequency of auxotrophic markers of B.pumilus 289 was on the order of 10-6 transductants per PFU.The transduction frequency of Str2 (streptomycin-resistance) from B.fumilus 1037 to B.pumilus 289 was on the order of 10-6 to 10-7更多还原
