Promotion effects of SP on different lignocellulosic substrates. Effect of SP loadings on the ECs of glucan in substrates with various severity factors at cellulase loadings of a 12.1 mg protein (5 FPU)/g glucan and b 24.2 mg protein (10 FPU)/g glucan for bamboo; c the inhibition of added lignin to the ECs of microcrystalline cellulose (Avicel); d the effect of SP addition on Avicel, Avicel–lignin mixture, and eucalyptus and Masson pine substrates. The time of enzymatic hydrolysis was 72 h
