摘要: Particles having a diameter of 0.1–0.4 μ were isolated from cultures stable Proteus L form by means differential centrifugation. Electron microscopic investigations showed that these particles consisted peripheral “unit membrane” surrounding varying amounts granular material, probably ribosomes. No nuclear equivalents could be seen in the particles. This is accordance with earlier studies showing small (diameter
