  1. Different letters indicate significant differences between the yeast strains (p < 0.05)
  2. Data represent the mean ± SD from three independent experiments
  3. 1Theoretical yield of ethanol from xylose is 0.51 gp/gs, theoretical yield is calculated as ethanol yield multiplied by 100 and divided by 0.51
