Spheroplasts are formed 15 min after the addition of penicillin. Swellings appear at the end or in the middle of the cell. Buds were found on the surface of the spheroplasts. As was found by scanning electron microscopy, the surface of the spheroplasts is folded and, during later stages, wrinkled. "Expulsion" of mesosomes into the periplasmic space was found, as well as separation of vesicles, formed by the outer and cytoplasmic membranes, from the cell surface. The two fracture faces of the outer membrane are uncomplementary; the convex fracture face is mainly smooth but contains occasional dents of the rod-like shape while the concave face does not contain them. The outer (true) surface of the cell wall is smooth. The similarity and differences between the protoplasts, spheroplasts and L forms are discussed . The protoplasts and spheroplasts may divide, grow and multiply under definite conditions of cultivation, like the L forms do, but they do not possess the well developed intracytoplasmic membrane system typical of the L forms.
