Total cellulolytic activity in different carbon sources. T. reesei QM9414 strain was grown in cellulose, lactose, or cellobiose for 24, 48, and 72 h, in glucose for 24, and 48 h, and in sophorose for 2, 4, and 6 h. Activity was measured using the azure-Cellulose method and is expressed as the ratio between growth factor and the absorbance obtained in the standard curve equation, per minute, and per amount of enzyme added to the reaction
