Hemicellulase, amylase activity analysis and protein content of five strains in complex carbon source medium. A–C Xylanase, pNPXase and amylase activities of five strains. D Extracellular protein content of five strains. Data represent mean ± SD from triplicate cultivations. Statistical significance of the differences between strains was calculated for transcriptional levels of endogenous genes. *p < 0.05, **p < 0.01, ***p < 0.001
