Antimicrobial action of p-hydroxybenzoic acid esters (parabens) on Escherichia coli JE 1011 was investigated under mild heating conditions, from the viewpoint of membrane disorder or degradation. By mild heating at 45, 48 or 50°, cardiolipin in phospholipid was increased with a corresponding decrease of phosphatidylglycerol. The phenomenon represents an adaptation of the bacterium to the external environment. A change of fatty acid composition, representing ordinary bacterial adaptation to a change of environmental temperature, was not found. On the other hand, heating in the presence of butyl-paraben caused the accumulation of membrane degradation products such as free fatty acid and lysophospholipid. Electron micrographs of treated cells supported the above results.
