Cellulolytic (A) and hemicellulolytic (B) enzyme gene expression levels of P. oxalicum GZ-2 grown on different substrates for 48 h. The error bars indicate the standard deviation of three replicates. Values in different treatments followed by the same letter are not significantly different according to Tukey's honest significant difference (HSD) test (capital letters indicate P <0.01; lowercase letters indicate P <0.05).
