查询词典 alkali grass

Firstly, the methanolysis of different oils by alkali-catalysis and lipase-catalysis werestudied.

首先，本文分别采用酶法和化学法对不同来源的油脂和甲醇转酯化反应进行了考察和优化，对不同催化剂催化生产生物柴油进行了对比。

The crudeglycerol from biodiesel production could be directly converted to 1,3-PD without any priorpurification. In flask cultures, the 1,3-PD yields of 0.62 and 0.44mol/mol on crude glycerolfrom lipase-and alkali-catalyzed methanolysis of soybean oil were lower than that of0.68mol/mol on pure glycerol. In fed-batch fermentations, the 1,3-PD yields of 0.47 and0.46mol/mol on crude glycerol were comparable to that of 0.49mol/mol on pure glycerol.

生物柴油的副产物甘油不经纯化可以直接用来发酵生产1，3-丙二醇，在摇瓶培养中，由酶法和碱法得到的甘油获得的1，3-丙二醇的转化率分别为0.62mol／mol和0.44mol／mol，而纯甘油得到的转化率为0.68mol／mol；在批式流加发酵中，由酶法与碱法得到的甘油和纯甘油得到的1，3-丙二醇的转化率相差不大，分别为0.47mol／mol、0.46mol／mol和0.49mol／mol，纯甘油得到的生产强度最高，为2.0g／，两种粗甘油得到的生产强度都为1.7g／。
