The influence of germicides on the dehydrogenases ofBact. Coli: Part I. The succinic acid dehydrogenase ofBact. Coli

Abstract

1. The effect of alcohols and of phenol on the succinic acid dehydrogenase ofBact. coli, hitherto recorded qualitatively in the literature, has been studied in greater detail.2. The effect of heat and ofp−chloro−m−cresol, hexyl resorcinol,p−butyl phenol and amyl−m−cresol, has also been studied.3. The concentrations of these germicides required to inhibit completely the succinic dehydrogenase is such as to allow for a slight excess over the concentrations which are lethal toBact. coli.
