THE BACTERICIDAL ACTION OF OZONE  The use of ozone as a gaseous disinfectant has often been advocated, but the claims made for its efficiency have little or no experimental basis. [Review of earlier investigation omitted.]Our own experiments have been carried out (1) to determine the germicidal action of ozone on pure cultures under the conditions commonly used in testing disinfectants, and (2) to determine the effect of ozone on the ordinary air bacteria.All experiments were carried out in a small room of about 26 cubic meters. There was one door and one window in the room. In the first experiment there was ventilation to the room through a 3-inch hole in the window.
