Sudies on the Antiseptic Action and Toxicity of Mercuric Chloride Part 1. On the Antiseptic Action of Mercuric Chloride and the Adsorption of Radio Isotope Hg(203)Cl(2) on Bacteria from the Standpoint of the Oxygen Consumption

The auther studied the influence of mercuric chloride on the respiration of bacteria and the adsorption action of Hg(203)Cl(2) on E. coli eommunis; and obtained the following results. 1. The mercuric chloride action on the respiration of bacteria: a. The action of mercuric chloride acting upon the oxygen consumption of 10 mg by Coli communis begins to decrease at 5×10(-5)%, while it is completely stopped at 5×10(-4)%. b. The action of mercuric chloride acting on the oxygen consumption of 10 mg by Typhus abdominalis 57 S begins to decrease at 5×10(-4) and it almost disappears at 5×10(-2)%. c. The action of mercuric chloride on the oxygen consumption of 30 mg by Staph. aureus (Terajima strain) commences to diminish at 5×10(-5)% , and it disappears almost completely at 10(-2)%. 2. The action of radio-isotope Hg(203)C1(2) on the respiration of E. coli eommunis: a. It has been confirmed that clearly Hg ions of the mercuric chloride solution adsorb to E. coil communis. b. In the case where the culture time of Coli communis is prolonged, the adsorption of Hg ions has been found to rise clearly in proportion to the lapse of the time. c. In the case where the density of the mercuric chloride solution is altered, it has been recognized that the higher the concentration of the mercuric chloride solution, the higher the adsorption rate of ions would be.
