摘要: The nomenclatural type by monotypy (Murray, 1984a) is the class Mollicutes, which consists of very small prokaryotes that are devoid cell walls. Electron microscopic evidence for absence a wall was mandatory describing novel species mollicutes until recently. Genes encoding pathways peptidoglycan biosynthesis absent from genomes more than 15 have been annotated to date. Some do possess an extracellular glycocalyx. confers such mechanical plasticity most readily filterable through 450 nm pores and many some cells in their populations able pass 220 or even 100 filters. However, they may vary shape coccoid flask-shaped helical filaments reflect flexible cytoskeletal elements.
