In the previous paper⁽¹⁾ the author reported that the quantity of the ergot alkaloid which could be found both in the mycelium and in the culture medium at a certain period of the culturing process was considered to be the balance, in the former, between the total alkaloid permeated into cells and that decomposed therein, while in the latter, between the total alkaloid excreted into the culture medium and that permeated into cells therefrom, by that time; that is, the decrease of the ergot alkaloid in the culture medium culturing the ergot fungus was attributable, not to the decomposition, but to the permeation into cells.
In the present work the author has dealt with the observation that an ergot alkaloid in certain solutions decreases in the same manner as in the culture medium culturing the ergot fungus when these were subjected to microbial contamination. The study has resulted in the conclusion that the observation should also be ascribed to the permeation of alkaloid into cells.
