a Gas chromatographs of the dodecane phase of two-phase cultures of E. coli strains DLG (top panel) producing several terpenols, and DLGA1 (bottom panel) producing only geranyl acetate. b The total production (mg/L) of either geraniol or geranyl acetate produced by strain DLG and DLGA1, respectively in 250 mL non-baffled flasks. c Geranyl acetate production by E. coli strain DLGA1 after 24 h when supplemented with 5 mM, 10 mM or 20 mM acetic acid in 250 mL baffled flasks. Products were analysed after 24 h of growth at 30 °C. Chromatograph peaks for citronellol, nerol, geraniol, farnesol, and geranyl acetate are indicated. Data are the mean ± standard deviation from three biological replicates
