Fig. 3From: Xylose fermentation efficiency of industrial Saccharomyces cerevisiae yeast with separate or combined xylose reductase/xylitol dehydrogenase and xylose isomerase pathwaysEnzymatic activities of XR with NADH (a), XR with NADPH (b), XDH (c) and XI (d). Biomass was collected at 24 h of fermentation in YPX medium at 30 °C and 40 °C in oxygen-deprived conditionsBack to article page
