A Intracellular pNPGase activity. B, C Intracellular and extracellular glucose concentration. D The relative mRNA level of cre1. E Cellulase activities and protein secretion of recombinant T. reesei OEcel1B with/without 0.25% cellobiose. Strains OEcel1B with/without Cu2+ and RUT-C30 were cultured in TMM + 2% cellulose for 168 h. Data are represented as the mean of three independent experiments, and error bars express the standard deviations. Asterisks indicate significant differences (*p < 0.05, **p < 0.01, ***p < 0.001) as assessed by Student’s t test
