- W980858052 abstract "以筛选得到的高产菌株Pleurotus eryngii-Co007为研究对象,考察4种不同吸附型固定化载体对其生长和产酶的影响。采用摇瓶发酵,以未添加载体接种发酵作对照,研究Pleurotus eryngii-Co007的生长代谢情况,测定发酵液中木质素降解酶的含量,并测定了固定化载体培养得到的Pleurotus eryngii-Co007菌丝体再利用产木质素降解酶的含量。结果表明,在发酵培养基中,添加固定化载体体系中的菌丝体生物量较对照组高,其中尼龙布效果最好,是对照组生物量的1.2倍。载体的添加能促进木质素降解酶的合成,在发酵培养基中,以尼龙布为载体所产生的木质素降解酶活性最高,达到190.67 U/mL,是对照组的1.9倍。在缓冲液体系中考察不同载体对菌丝体再利用产木质素降解酶的影响,结果表明,在缓冲液体系中Pleurotus eryngii-Co007产木质素降解酶要优于发酵培养基;除厨用无锈钢丝海绵外,其他吸附型载体的添加均较对照组提高了再利用菌丝体的产酶量并提前了产酶时间;菌丝体二次利用产生的木质素降解酶量远高于三次利用。在添加多孔陶粒载体的固定化体系中,菌丝体二次利用时产生的木质素降解酶活性达到最高,在第7天活性为306.41 U/mL,较对照组提高25%,且高峰期提前2 d。表明,吸附型固定化培养利于Pleurotuseryngii-Co007的生长和木质素降解酶的合成。" @default.
