Figure 4 . a) Oxidation of perillyl alcohol, nerol and
farnesol to aldehyde and carboxylate forms. b) GC/MS extracted
ion chromatograms (EIC) of aqueous phase sample of biotransformation of
(ⅰ) perillyl alcohol, (ⅱ) nerol and (ⅲ) farnesol with BGA01(lower row) and its parent strain (upper row). BGA01 harbored
the plasmid overexpressing CdGeDH and CdGaDH under the control of
PT7. Peaks numbered on each EIC are identified as 1,
perillyl alcohol; 2, perillic acid; 3, nerol; 4, nerolic acid; 5,
geranic acid; 6 & 7, farnesol; 8, farnesal.
