Figure 6From: Enhancing cellulase and hemicellulase production by genetic modification of the carbon catabolite repressor gene, creA, in Acremonium cellulolyticus Expression of cellulase and xylanase genes. Strains were cultured in medium containing 50Â g/L of cellulose for 24Â h (A), 72Â h (B), 120Â h (C), or in 10Â g/L of glucose and 40Â g/L of cellulose for 48Â h (D). Expression levels are shown relative to that of gpdA as an internal control. Black bars, YDCre; white bars, YPyrF. Data are presented as the mean of three experiments.Back to article page
