GC-FID and GC–MS analysis of C₅, C₁₀, and C₁₅ isoprenoid alcohols and their derivatives from engineered E. coli strains. GC-FID chromatograms (A) and mass spectra (B) of culture extracts obtained from recombinant E. coli strains NA-MBF1.0 and NA-MBF2.0. The GC-FID peaks and their corresponding compound are a isoprenyl acetate; b isoprenol; c prenyl acetate; d prenol; e citral; f geranyl acetate; g geraniol; h Z,E-farnesal; i farnesyl acetate; j E,E-farnesal; and k farnesol
