摘　　要：用不同的包埋载体和方法,将青霉X5进行包埋固定,并作染料脱色实验,研究各种载体的优缺点和不同方法固定菌体的活性,结果表明:使用4.5％海藻酸钠,7.5％活性炭粉和3％CaCl_2的包埋方法较易操作,菌体的物理强度较好,菌体表现为较好活性,对50mg/L的蒽醌染料的脱色率可达94.31％。A study was done on immobilizing penicillium X5 with different materials and methods and with some tests on decolorization of anthraquinone dye. The results showed that the immobilized carrier made of sodium alginate(4. 5%), activated carbon(7. 5%), and CaCl2(3%), had a better strength and activity of mycelium, and the decolorization rate of Reactive Brilliant Blue KN-R(50mg/L) could reach 94. 31%.
