[Effect of a synthetic analogue of bacterial anabiosis autoinducers hexylresorcinol on the stability of membrane structures].


PMID 19382705

Abstract

The effect of hexylresorcinol (HR), a chemical analogue of microbial anabiosis autoinducers of the alkylhydroxybenzene (AHB) group, on the stability of biological membranes and monolamellar liposomes formed of egg phosphatidylcholine (ePC) was studied. According to spectrophotometry and electron microscopy studying of HR-loaded liposomes in the presence of a surface-active agent Tween 20, the critical ratio between HR and ePC for liposome preservation was found to be close to equimolar. The trends in HR influence on membrane structural organization and stability confirmed in experiments on liposomes were also reproduced on intact bacterial cells explaining non-species-specific effect of AHBs. The demonstrated high efficiency of AHB biocides may be used in material and equipment protection against biocorrosion.
