  1. Data obtained from 2-h reactions show the average and the standard deviation from three independent experiments
  2. 1The percentage yield was calculated based on a theoretical maximum (0.51 g ethanol/g glucose consumed). The different letters (a–c) in the same column indicate significant differences between the samples (one-way ANOVA followed by Tukey’s HSD test, P < 0.05)
