Semomose not a Normal Structure of Bacterial Cell but a Artifact

Abstract: Bacterial mesosome had been considered as membranous vesicle organelle， and with many functions， synthesizing several enzymes， DNA and cell wall， taking part in respirations， cell division， and spore formation， from 1950s. But it had been debated that the existence of true bacteria cell structure because of mesosome extraction difficulty and lack of direction evidences for structure and functions. Mesosome was confirmed that it was an artifact when preparing a section for electron micrographs and not a true bacterial cell organelle by a method for high-resolution observation of sectioned， frozen-hydrated biological material in 1980s. Nevertheless， the textbook editors had not recognition the experiments results extremely， and remained mesosome expatiation up to now. Mesosome controversy gave us many lessons and apocalypses.
