Content of each type of fatty acids was shown as the normalized peak area (area/mg) by GC. The first three columns were the mean peak area and the standard deviation of each fatty acid as well as the total area from three replicates. The last two columns represent the relative content of each fatty acid as well as the total lipid in CoaR(+) or CoaR(−) to that in WT
