Calorimetric study of activity of the m-alkoxyphenols on the metabolism of Chromobacterium violaceum: Simultaneous measurements of dissolved oxygen tension

Calorimetric power versus time curves together with simultaneous measurements of dissolved oxygen for metabolism of Chromobacterium violaceum at 25 °C are reported in order to study the effect of a homologous series of m-alkoxyphenols. The inhibitory action of the compounds followed the order m-penthoxyphenol > m-buthoxyphenol > m-propoxyphenol > m-ethoxyphenol > m-methoxyphenol. The hydrophobicity of these compounds is inversely proportional to respective rates of oxygen consumption or heat production.
