香菇菌丝体中SOD的提取工艺研究

摘要

Using the direct method (without any treatment ) ,to extract superoxide dismutase (SOD ) of the mushroom mycelium ,and optimize the separation and extraction conditions .The optimal extraction technology of SOD in mushroom mycelium was phosphate buffer pH 7.8 ,concentra-tion was 50mmol/L ,2 times volume and extracted twice .%采用直接法（对菌丝体不作任何处理）提取香菇菌丝体中的超氧化物歧化酶（SOD ），并对SOD分离提取条件进行优化。香菇菌丝体中SOD的最佳提取工艺为磷酸缓冲液pH 7.8、浓度50mmol／L、2倍体积、抽提2次。
