Repellents for Escherichia coli operate neither by changing membrane fluidity nor by being sensed by periplasmic receptors during chemotaxis.

Abstract excerpt

A long-standing question in bacterial chemotaxis is whether repellents are sensed by receptors or whether they change a general membrane property such as the membrane fluidity and this change, in turn, is sensed by the chemotaxis system. This study addressed this question. The effects of common repellents on the membrane fluidity of Escherichia coli were measured by the fluorescence polarization of the probe...
