aCells were grown in YEB medium for 36 h at 28 °C or 15 °C. Total lipids were extracted and transesterified to fatty acid methyl esters and products were identified by GC-MS. Values represent percentages of total fatty acids and are means ± standard deviations of three independent experiments. b n-C14:0 3-OH, 3-hydroxyltetradecanoic; iso-C15:0, 13-methyl-tetradecanoic acid; anteiso-C15:0, 12-methyl-tetradecanoic acid; n-C15:0,pentadecanoic acid; iso-C16:0, 14-methyl-pentadecanoic acid; n-C16:1cis-9, cis-9-hexadecenoic acid; n-C16:0, hexadecanoic acid; iso-C17:1 cis-9, cis-9-15-methyl-hexadecenoic acid; iso-C17:0, 15-methyl-hexadecanoic acid; anteiso-C17:0, 14-methyl-hexadecanoic acid; n-C17:0 cyclo, 9,10-methylene hexadecanoic acid; n-C18:1, cis-11-octadecenoic acid; n-C18:0, octadecanoic acid
