摘要：Solid state fermentation with different lignocellulolytic materials as inducers was used for lignocellulolytic enzyme production in this study. Pleurotus ostreatus strains were assessed by measuring laccase, CMCase, and xylanase activities. The secretion potential of the lignocellulolytic enzymes by wild and cultivated strains was analyzed for the first time. The wild and cultivated strain showed their unique capacities for secreting lignocellulolytic enzymes on solid-state fermentation with different lignocellulosic materials. The wild P. ostreatus strain preferred corncob for the secretion of laccase and xylanase activity, but the cultivated strain preferred poplar sawdust. The wild strain and cultivated strain showed a consistent preference for poplar sawdust for the secretion of CMCase activity. The wild strain was advantageous because it achieved the maximum hydrolytic enzyme activities within a short time period. Poplar sawdust and corncob were conducive to laccase secretion by the wild or cultivated strains and the rapid accumulation of laccase on solid-state fermentation. Additionally, continuous, stable laccase production was an extremely important advantage by solid-state fermentation of poplar sawdust, particularly in the wild strain. These findings are helpful in selecting the appropriate strain that corresponds to suitable lignocellulosic materials. The optimization of integrated industrial lignocellulolytic enzyme production can also be achieved.
