b-glucosidase activity was also evaluated in fermentations performed by A. strictum on different substrates. As can be observed in Fig. 2d, the b-glucosidase activity peak was similar in all cultivations, being obtained after 240 h of fermentation. Cultivation on sugarcane bagasse with mild pre-treatment presented the best results, indicating a maximum b-glucosidase activity of 3.48 U/L at 240 h of fermentation. The fermentation using AVICEL,as
