Figure 3 Effects of auxotrophic genes from succinyl-CoA module
on cell growth and FFA production. Control: prototrophic strain;met15 Δ: strain ScYan10 with single deletion of gene MET15 .
Growth curve (A) and fatty acid titers (B) at fermentation endpoint (48
h) of met15 Δ were measured by adding exogenous methionine of 100,
500 and 1,000 mg/L, respectively. All data was represented as the mean ±
s.d. of three clone samples.
