Fig. 1From: An accessory enzymatic system of cellulase for simultaneous saccharification and co-fermentationGene copy number and enzyme activity of the recombinant yeast strains with δ integration and Di-CRISPR, respectively. The values and error bars represent average readings and standard deviations for 3 qPCR reactions. *Indicates statistically significant differences between Di-CRISPR and conventional delta integration populations (student's t test, p < 0.05)Back to article page
