We treated microorganisms using ultra high pressure underwater shock wave. In addition, we have observed with a scanning electron microscope and a microscope. Body surface of Brachionus plicatilis was destroyed and the contents spilled. The body surface of Chlorella were destroyed significantly. Although there was no big crack in the body surface as a result of carrying out the shock treatment of Microcystis, it turned out that the pigment is missing. These results have suggested that the damage of the living body by the shock wave is depende nt on the hardness of the body surface. That is, in the case of a living body with the hard body surface, the shock wave reflects at the bo dy surface, but in being a soft body surface, it penetrates the inside of the body.
