Abstract

The effects of temperature and growth rate on the fatty acid composition of the extractable lipids of four mesophilic and three psychrotrophic bacteria were examined. Two of the mesophiles ( and ) increased the proportion of unsaturated fatty acids in their lipids with decreasing temperature over their whole growth temperature range. The other mesophiles ( and ) increased the proportion of unsaturated fatty acids with decreasing temperature only over the lower half of their growth temperature ranges. The psychrotrophs and sp. had a constant proportion of unsaturated acids over the lower half of their growth temperature range, while the psychrotrophic sp. showed no consistent change in its unsaturated fatty acid composition with temperature. All species showed some variation of unsaturated fatty acid composition with growth rate at the highest and lowest growth temperatures, although such variations were small in some species ( and sp.).
