Homeoviscous adaptation, growth rate, and morphogenesis in bacteria

Biophys J. 1985 Aug;48(2):337-9. doi: 10.1016/S0006-3495(85)83788-7.

Abstract

Fluorescence polarization, P, of 1,6-diphenyl-1,3,5-hexatriene was studied in Escherichia coli B/r. Modification of nutritional conditions was not compensated by homeoviscous adaptation, demonstrated to exist for temperature variations. Cell diameter, which is known also to vary with nutrition but not with temperature, was found to be positively correlated with 1/P, and may therefore be regulated by membrane lipid order and fluidity.
