Several cultural conditions for high laccase production by Trametes versicolor, including initial medium pH value, metal ions Cu(superscript 2+) and Mn(superscript 2+) contents, types of inducers, as well as dosage and adding time of inducers were studied and optimized. The result showed that T.

对一株漆酶高产白腐菌―彩绒革盖菌的培养和产酶条件，包括培养基初始pH值、金属离子Cu(上标 2+)和Mn(上标 2+)的含量，以及诱导剂的种类、添加量和添加时间等相关因素进行了优化。

Versicolor suited to grow and produce laccases at pH value 3.5-5.7, and unbuffered media were able to get good laccase productivity though buffered media could get higher laccase activity. Metal ions Cu(superscript 2+) and Mn(superscript 2+) in the culture could remarkably increase the activity of laccases. The optimal concentration of Cu(superscript 2+) was 0.008-0.08mmol/L, and the optimal concentration of Mn(superscript 2+) was about 0.01mmol/L, when the culture contained 0.1mmol/L 2,5-dimethoxyaniline.

结果发现该菌种适宜在pH值3.5~5.7环境下生长并合成漆酶，培养基中添加缓冲液可以获得更高的酶活，但不加则有较高的酶产率；铜和锰可以显著提高漆酶活力，当以0.1mmol/L 2，5-二甲基苯胺为诱导剂时，培养基中宜含0.008~0.08mmol/L Cu(上标 2+)，0.01mmol/L左右的Mn(上标 2+)。

CO conversion of 80.27%, 78.41% and 61.14% and selectivity to C(superscript + subscript 5) of 88.54%, 88.57% and 77.95%, respectively, were obtained for Fischer-Tropsch synthesis under n(H2): n=2.0, 483 K, 1.5 MPa and 800h^(-1) over uncalcined catalyst, those calcined at 673 K and 923 K.
