Percentages are based on total peak area from GC analysis; MS spectra were used to confirm peak identities. Data are reported as averages of 3 biological replicates with standard deviation. While the amount of FFA excreted by the wild type is negligible due to recycling via acyl-ACP synthetase, FFA are detected from GC/MS analysis, most likely due to contaminating membrane components found in the supernatant.
