Influence of overexpression of a propionyl-CoA synthetase on 3-ethylphenol (A) and 3-methylphenol (B) formation with and without supplementation of external propionate. Yeast strains CEN.PK2-1C expressing the 3-methylphenol pathway (PpoptMSAS, optnpgA and optpatG14) and additionally the propionyl-CoA synthase optprpE, with or without the Δcit2Δcit3 double deletion (strains JHY185 and JHY218, respectively), were inoculated at an OD of 5 and cultivated for 144 h in KPi buffered YPD medium (pH 6.5) with or without supplementation of 10 mM propionate. Culture supernatants were analysed via HPLC for 3-alkylphenol production. Error bars represent standard deviations of biological duplicates.
