以白腐真菌的模式菌种-黄孢原毛平革菌作为研究对象,探究固定化黄孢原毛平革菌对邻苯二甲酸二乙酯（DEP）的降解效果及其最佳降解条件.研究表明,固定化黄孢原毛平革菌相对于游离态菌体能产生较高活性的木质素过氧化物酶（Li P）和锰过氧化物酶（Mn P）.DEP降解效果受固定化菌体接种量、p H值、温度和DEP初始浓度等因素的影响.当p H为6,温度为35℃,DEP初始浓度为10 mg/L时,加入8 g固定化黄孢原毛平革菌时,DEP去除效果最好,其去除率达到94.6%.

The biodegradation ability as well as the optimum degradation conditions of diethyl phthalate （DEP） were investigated by the white-rot fungus model species-Phanerochaete chrysosporiumwas investigated. The results showed that the LiP and MnP activities of the immobilized P. chrysosporium are higher than that of free mycelium. The DEP degradation is influenced by the immobilized inoculation dose, pH, temperature, and initial DEP concentrations. The maximum biodegradation efficiency is observed at ...
