Cellulose digestibility of wheat straw degraded by M. cinnamomea N12 (a) and the correlation between cellulose digestibility and degradation extent of WS component during SSF (b). The cellulose digestibility of the biotreated WS was calculated as the ratio of cellulose hydrolyzed (0.9 × glucose) to the theoretical cellulose in the biotreated WS. WS without fungal inoculation was used as the control. Error bars indicate standard errors of the mean value of three replicates. Significant difference was indicated by different lowercase letters as evaluated by ANOVA at p < 0.05
