Analysis of hydrolysis ability of crude enzymes against filter paper. The culture supernatants of the BGL(X) over-expression mutants and the parental strain RE-10 were sampled at 120 and 144 h. The released glucose from filter paper was measured. Data are the means of three biological replicates and error bars show the standard deviation. Asterisks represents the significantly difference between the mutant and the RE-10 (*p ≤ 0.05; **p ≤ 0.01)
