In all experiments, a total enzyme load of 36 FPU (g glucan)-1 and a yeast load of 4 g L-1 were used. a Related to total amount of available xylose. b Related to consumed xylose. c Corresponding to the maximum theoretical yield on total available sugars. d An extra yeast addition (2 g L-1) was made at t = 24 h (see last paragraph in the results section). |
