介绍了铜阳极泥湿法处理过程中硒渣的来源及其成分，并且通过理论分析和试验证明采取真空蒸馏可以回收硒渣中的硒，所得到的粗硒含硒量大于96%。

If the base was added again to above solution until pH≥13, the resinoid substance was separated from it.

以分光光度法，于740 nm波长下测定含0.98％正丁醇的0.5％PVA与铜盐组成的(pH=10)不同浓度(5～50 mg CuCl_2·2H_2O/100 ml)的水溶液吸光度，并对CuCl_2·2H_2O摩尔浓度作图，它遵守朗伯—比耳定律。

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+)。
