Cellulase and xylanase production in DBDace2-VP16 transformants. DBDace2-VP16 transformants and RUT C30 were cultured on 2% avicel or lactose after a shift from glucose. FPase (a), pNPCase (b), CMCase (c), pNPGase (d), xylanase I (e), and xylanase II (f) activity (U/mL), and extracellular secreted protein concentration (g) were measured at 72, 96, and 120 h. Error bars show the respective standard deviation of three biological replicates; asterisks indicate significant differences (*p ≤ 0.05) between the transformants and the parental strain RUT C30, as assessed by Student’s t test
