昇汞の消毒作用並びに毒性に関する研究 第1編 酸素消費量より見たる細菌に対する昇汞の消毒作用並びに大腸菌(E.Coii communis)の同位元素Hg(203)Cl(2)の吸着作用に就いて

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.
