Fig. 3From: Stepwise metabolic engineering of Candida tropicalis for efficient xylitol production from xylose mother liquorEffect of coenzyme regeneration systems. Comparisons of: a cell mass, b xylose consumption, and (c) xylitol titer among C. tropicalis strains XZX-B4Z, which expresses YlZWF; ZX-B4ZG, which overexpresses both YlZWF and YlGND; and XZX-B4M, which overexpresses YlMAE. The control strain, XZX-B3 is the precursor of parent XZX-B4 that retains the URA3 marker. Error bars indicate standard deviations from the means of triplicate biological replicates. Differences were analyzed by Student’s t-test. **p < 0.01, *p < 0.05; “ns” means not significantBack to article page
