title: [Physicochemical characteristics of the Penicillium-bacterial virus type 5 and its nucleic acid].
abstract: Physico-chemical characteristics of PBV-5 virus and its nucleic acid were studied. Morphologically, the virus is a rectilinear polyhedron 270 A in diameter, without a process. The sedimentation constant of a virus particle is 117S, the buoyant density of the virus in cesium chloride density is 1.437 g/cm3. As shown by qualitative reactions with orcinol and diphenylamine, the virus contains DNA. The viral DNA preparation in CsCl gradient solution showed the buoyant density 1.719 g/cm3. Electron microscope examination of a PBV-5 DNA preparation showed the nucleic acid molecules to be single-stranded rings.
