Transmission electron micrographs of high-pressure frozen and cryosubstituted Verrucomicrobium spinosum. A. Cell prepared by high-pressure freezing and cryosubstitution showing prostheca (PT), paryphoplasm (P), and an intracytoplasmic membrane (ICM) enclosing a pirellulosome region containing a condensed fibrillar nucleoid (N). Inset: enlarged view of area of cell outlined in the white box showing cytoplasmic membrane (CM), paryphoplasm and ICM. B. freeze-fracture replica of cell showing cross-fractured paryphoplasm (P) and fracture faces of ICM and CM. Bar – 500 nm
