白腐菌Panus conchatus在液体培养条件下产生了漆酶,经纯化分离后用于对苯基苯酚的催化聚合,探讨了反应温度、缓冲溶液pH以及反应体系中溶剂二氧六环的含量对漆酶催化对苯基苯酚聚合的影响.结果表明,漆酶催化对苯基苯酚聚合反应的最佳反应条件为:温度为40℃,混合溶剂中二氧六环的体积百分数为85%,缓冲溶液为pH=4的0.2mol/L HAc-NaAc溶液.在此条件下用漆酶催化对苯基苯酚聚合,得到了重均分子量Mw=80533的聚酚产物,得率为75.5%.

Panus conchatu, a white rot fungus, could produce high activity laccase in the submerged culture. The polymerization of 4-phenylphenol was carried out in the mixture of buffer and organic solvent catalyzed by the purified laccase. The effects of temperature, amount of dioxane in the mixture and the pH of buffer have been systematically investigated. The best condition for this polymerization is that the temperature is 40°C, the amount of dioxane in buffer is 85(vol)% and the pH of buffer is 4. At this conditions, the polymerization of 4-phenyl...
