Compararive analysis of Penicillium oxalicum HP7-1 after cultured in medium containing 1% glucose and 1% Avicel respectively, in order to explaining the mechanism of cellulase and xylanase production at protein level. Identify the small proteins encoded by the predicted sORFs based on the genomic analysis using mass spectrometry and analyze their expression under cellulose-induction and non-induction conditions.
