In the preceding paper, it was reported that the yield of yeast grown under the lack on Z^<++>n was only a small fraction as compared with that grown in the culture medium with the addition of Zn^<++>. In order to clarify this phenomenon, experiments were carried out as a preliminary study, the results of which are briefly summarized as follows : - 1) A solution of a mixture of various amino acids was fed to the yeast, the vitality of which had been lowered in the culture medium without Zn^<++>, but it did not stimulate the growth of yeast.2) Owing to the lack of Zn^<++> in the culture medium, the consumption of sugar by the yeast was highly inhibited, but there accumulated a pretty large amount of acetaldehyde on the basis of the sugar consumed.3) Qo_2 of the yeast grown in the absence of Zn^<++> was 22.2,while that of the yeast grown in its presence was 42.0.
