The activity analysis of extracellular prolyl endopeptidase under various carbon sources. T. reesei strain was pre-cultured in a minimal medium supplemented with 2% glucose for 48 h, then the mycelium was shifted to the MM containing two inducers [wheat bran & Avicel (A) and wheat bran & corn cob (D)] or a single inducer [wheat bran (B), Avicel PH101 (C), corn cob (E), and straw powder (F)]. After 4 days of fermentation, the supernatant was sampled for activity analysis. The error bar denotes the standard deviations (SD) of three technical repeats (*p < 0.05, ***p < 0.001, ns: not significant)
