title: Temperature-induced differences in growth rate and fatty acid composition in two strains of Escherichia coli 15T-.
abstract: The saturated/unsaturated fatty acid ratio of Escherichia coli 15T- decreases almost threefold as growth temperature decreases from 43 to 27 degrees C, wheras the ratio of a fast-growing mutant derived from 15T- changes only half as much. Strain 15T- experiences a 2.4-fold change in doubling time across this temperature range, but doubling time in the mutant changes 3.3-fold.
