ABSTRACT
A new thermophilic fungus J18 isolated from the soil samples was identified as Paecilomyces thermophila. This strain produced effectively xylanase utilizing several lignocellulosic materials in the solid-state fermentation (SSF) , and wheat straw was the best carbon source. The results of single-factor-experiment showed that the wheat straw of particle size 0. 3 mm ~ 0.45 mm, initial moisture content of 83% , initial pH of 7. 0 and cultivation temperature of 50℃were the optimal conditions for xylanase production. Under the optimized conditions, it produced 18 580 U/g dry substrate after 8 days of cultivation. Therefore, xylanase production by Paecilomyces thermophila in SSF possess great potential for commercial applications.
