摘要
考察了3种单组分分散剂PSE、MGE和OPG及其复配体系PSEMGE、PSEOPG和MGEOPG对甾体微生物转化体系的影响。试验表明:单组分分散剂PSE及复合型分散剂PSEMGE对甾体转化反应有利。其中单组分分散剂PSE的最佳施用量的质量分数为0.075%,复合型分散剂PSEMGE的最佳施用量因复配方式的不同而异。
The effects of three different kinds of mono-surfactants(PSE, MGE,OPG) and multiple surfactants (PSE-MGE, PSE-OPG, MGE-OPG) on steroid bioconversion system are studied in this paper. The results show that mono-surfactant PSE and multiple surfactants PSE-MGE have positive effects on bioconversion. A higher conversion rate can reach when using mono-surfactant PSE with the concentration of 0. 075 %. As for multiple surfactants PSE-MGE, the most appropriate surfactant dosage is different according to diverse methods of combing PSE and MGE.
