Summary

The fine structure of Micrococcus cryophilus was studied by means of the freeze-etching technique, and compared with previous studies on ultra-thin The freeze-etched cell showed structures similar to those observed in thin sections, the cell wall has a wavy surface structure and consisted of two layers. The cytoplasmic membrane fractured into two parts; one adhering to the cell wall, the other adhering to the cytoplasm; both were covered with spherical particles, 8–12 nm in diameter. In the cytoplasm, nuclear material, mesosomes, and aggregated spherical particles were observed. The results confirm that the cell structure of M. cryophilus is similar to that of Neisseria spp. cells. It should be therefore classified among non-pigmented, asaccharolytic neisserias.
