Molar percent conversion of styrene from cinnamaldehyde and 1,3-pentadiene from sorbic acid by strains of Saccharomyces cerevisiae

Yeast species (strain designation)% Conversion (±SD) for:
Styrene1,3-Pentadienea
S. cerevisiae (62)11.1 ± 1.51.03 ± 0.11
S. cerevisiae (633)6.5 ± 1.50.99 ± 0.06
S. cerevisiae (634)13.9 ± 4.00.91 ± 0.38
S. cerevisiae (635)13.2 ± 4.10.83 ± 0.01
S. cerevisiae BY4741, wild-type PAD16.1 ± 1.90.31 ± 0.04
S. cerevisiae Y05833, deleted pad100
  • a Tests were carried out in sealed bottles holding 10 ml ACM, pH 4.0, containing 1 mM sorbic acid or 0.1 mM cinnamaldehyde incubated for 10 h at 28°C. Data are based on two independent determinations of each value and the subtraction of uninoculated blanks.
