From: Three novel structural phenomena in the cellular ontogeny of Oenococcus oeni from northern China

Indications of SCP. (A) Spherical growth process. (B) Protrusions or indentations of the cell. (C) The cell wall with visible cell membrane integrity, intracellular organelles, and a visible nucleoid. (D,E (TEM), and F) Binary cell fission; chains with 2–8 spherical parts could be observed. (G) Binary cell fission exhibiting a longer chain appearance (16 globular parts). (H) During cell division, the membrane extension was clearly visible between the spherical cells. (I) Short chains of cells as observed by TEM. (J–L) The rupture or eruption of the PSS.
