Correlation of long-range membrane order with temperature-dependent growth characteristics of parent and a cold-sensitive, branched-chain-fatty-acid-deficient mutant of Listeria monocytogenes.

Abstract excerpt

Listeria monocytogenes is a food-borne, pathogenic, psychrotolerant bacterium that grows at refrigeration temperatures. Long-range membrane order of the parent (10403S) and of a cold-sensitive mutant ( cld-1) deficient in odd-numbered, branched-chain fatty acids was measured using the width of the central line of spectra of an electron paramagnetic resonance probe, 4,4-dimethyl-2-heptyl-2-hexyloxazolidine- N-oxyl...
