Fig. 1From: Glutamine involvement in nitrogen regulation of cellulase production in fungiEffect of different nitrogen sources on (hemi)cellulase activities and protein secretion of T. reesei RUT-C30 at 72 h. A Enzyme activities of T. reesei RUT-C30 cultured in TMM with the individual addition of different nitrogen sources of 2.92 g/L. B Enzyme activities of T. reesei RUT-C30 cultured with different nitrogen sources as a sole nitrogen source at 4 g/L. FPase: the filter paper activity; pNPCase: the CBH activity; CMCase: the CMC activity; pNPGase: the β-glucosidase activity; pNPXase: the β-xylosidase activity; Secreted protein: secreted protein concentration. Data are represented as the mean of three independent experiments and error bars express the standard deviationsBack to article page
