Temperate and virulent bacteriophages isolated from soil were shown to carry out generalized transduction of Bacillus stearothermophilus NUB36. A transducing frequency of 1 X 10(-5) to 7 X 10(-4) was obtained for temperate phages TP-42 and TP-56. The transducing frequency for virulent phage TP-68 was two to three orders of magnitude lower. Cotransfer analysis with the three phages showed that hom-1 is linked to thr-1 and that gly-1 is linked to his-1.
从土壤中分离出的温和噬菌体和烈性噬菌体可对嗜热脂肪芽孢杆菌NUB36进行普遍性转导。温和噬菌体TP - 42和TP - 56的转导频率为1×10⁻⁵至7×10⁻⁴。烈性噬菌体TP - 68的转导频率低两到三个数量级。对这三种噬菌体进行的共转移分析表明,hom - 1与thr - 1连锁,gly - 1与his - 1连锁。
