Abstract A new virulent bacteriophage, termed øRsV, was isolated from a local sewage plant on the facultative phototrophic bacterium Rhodobacter sphaeroides DSM 159 as the host organism. Electron microscopic studies revealed that in general morphology phage øRsV resembles the T-even Escherichia coli phages. The host range of phage øRsV was restricted to strains of R. sphaeroides. E. coli strains B and K 12 were not infected. The phage genome was characterized on the basis of thermal denaturation profiles and restriction analyses indicating that it consists of about 160 kb of double-stranded DNA lacking cohesive ends. The G+C content was determined to be 46.8 mol%.
