Table 3 Highest titers, yields and productivities achieved with YZy197

From: Xylose utilization stimulates mitochondrial production of isobutanol and 2-methyl-1-butanol in Saccharomyces cerevisiae

YZy197 Titera (g/L) Yielda (mg/g xylose) Productivityb (mg/L/h)
Isobutanol 3.10 ± 0.18 38.8 ± 2.4 32.6 ± 1.7
2-Methyl-1-butanol 0.79 ± 0.07 (0.91 ± 0.02)c 18.4 ± 2.8 16.3 ± 1.4
Total branched-chain alcohols 3.89 ± 0.25 57.2 ± 5.2 48.9 ± 3.1
  1. Values were obtained in CaCO3-buffered fed-batch fermentations in synthetic complete (minus uracil) medium, supplemented with a150 g/L xylose, or b100 g/L xylose
  2. cThe highest titer of 2-methyl-1-butanol was achieved in CaCO3-buffered batch fermentations in synthetic complete (minus uracil) medium, supplemented with 100 g/L xylose. Also see Additional file 1: Table S1
