Three new bacteriophages of Pseudomonas putida PpG1 have been isolated. Bacteriophages differ in many characteristics and are unrelated. Phage-resistant mutants of Pseudomonas putida PpG1 are selected using these phages and pf16 bacteriophage. No lysogenic variants were detected among these mutants. They have been distributed in seven groups according to their resistance to bacteriophages. The resistance to PMW phage was caused by at least two different mutations. Some of the phage-resistant mutants seem to cause the killing effect on Pseudomonas putida PpG1 cells.
已分离出恶臭假单胞菌PpG1的三种新型噬菌体。噬菌体在许多特性上存在差异且彼此无关。利用这些噬菌体和pf16噬菌体筛选出了恶臭假单胞菌PpG1的抗噬菌体突变体。在这些突变体中未检测到溶源变体。根据它们对噬菌体的抗性，已将它们分为七组。对PMW噬菌体的抗性是由至少两种不同的突变引起的。一些抗噬菌体突变体似乎对恶臭假单胞菌PpG1细胞具有杀伤作用。
