A DNA-containing bacteriophage, designated RS1, infecting Rhodopseudomonas spheroides 2.4.1, has been isolated from sewage. The buoyant density of RS1 in CsCl equilibrium centrifugation is 1.50 g/cm(3), and the buoyant density of RS1 DNA is 1.706. The phage possesses a polyhedral head, approximately 65 nm in diameter, and a tail 60 nm long. When grown on aerobic cells, RS1 has a latent period of 120 min and an average burst size of 20. When grown on anaerobic cells, RS1 has a latent period of 150 min, and a burst size similar to that observed during aerobic infection. The adsorption rate constant of RS1 to aerobic cells is 1.2 x 10(-9) ml/min, and 0.58 x 10(-9) ml/min to anaerobic cells. Adsorption of RS1 to R. spheroides requires the presence of divalent cations.
一种含有DNA的噬菌体，命名为RS1，可感染球形红假单胞菌2.4.1，已从污水中分离出来。RS1在CsCl平衡离心中的浮力密度为1.50 g/cm³，其DNA的浮力密度为1.706。该噬菌体具有一个多面体头部，直径约65 nm，以及一条60 nm长的尾部。在需氧细胞上生长时，RS1的潜伏期为120分钟，平均裂解量为20。在厌氧细胞上生长时，RS1的潜伏期为150分钟，裂解量与需氧感染时观察到的相似。RS1对需氧细胞的吸附速率常数为1.2×10⁻⁹ ml/分钟，对厌氧细胞为0.58×10⁻⁹ ml/分钟。RS1对球形红假单胞菌的吸附需要二价阳离子的存在。
