%X Penicillium simplicissimum(Oudem.)Thom BGA can secrete lignocellulolytic enzymes, among these enzymes the highest activities of hemicellulase, cellulase, lignin peroxidase(Lip), manganese peroxidase(Mnp) and laccase are 146.82 Iu·g-1, 2.78 U·g-1, 47.97 U·g-1, 34.56 U·g-1 and 17.94 U·g-1 respectively. According to the results and the statistical analysis of SPSS, the ability of secreting lignocellulolytic enzymes by Penicillium simplicissimum significantly correlated with the structure of lignocellulose, and the biodegradation of lignocellulose was probably a kind of synergistic effect of several lignocellulolytic enzymes. In the solid-state fermentation of 30 days, the hemicellulose content has a significantly negative correlation with the fermentation days(r=-0.946, P<0.01), there was also a significantly negative correlation between the cellulose-biodegradation and the lignin-biodegradation(r=-0.818, P<0.05). As unselected enzymes, Lip and Mnp can degrade hemicellulose and cellulose corporately when biodegrades lignin. The significant correlation is showed between Lip, Mnp and cellulose (correlation parameters are r=0.922, P<0.01; r=0.807, P<0.05 respectively). In addition, the biosorption is found to have a very important effect in the removal of liquid alkali lignin by Penicillium simplicissimum.
