查询词典 ethanol

Continuous ethanol fermentations with and without recycling of distillage were carried out in two suspended-bed bioreactors,respectively,using two-stage enzymatic hydrolyte of corn powder as medium.

在2个单级悬浮床生物反应器中，以双酶法制备的玉米粉糖化液为底物，进行了废液循环条件下自絮凝颗粒酵母乙醇连续发酵与清液发酵对比实验。对于废液循环实验，每隔5d将收集到的发酵液集中精馏处理，得到的废糟液直接用于玉米粉调浆。

该项研究将为以后在植物纤维原料制取酒精工业上建立7～12罐多级串联酒精连续发酵提供有力的理论依据。

In this paper, the dilute acid pre-treatment conditions, the detoxification methods, and the research progress in ethanol production from hemicellulose dilute hydrolyzate by P.

综述了稀酸预处理条件、脱毒方法和树干毕赤酵母发酵水解液生产乙醇的国内外研究进展。

It's very difficult to hydrolyze zein which is harder to be dissolved in water. It's found from this research that Alcalase can still keep a high activity and hydrolyze zein in 70% ethanol.

经研究发现，Alcalase酶能在70％的乙醇溶液中依然保持有较强的活性，能对zein发生水解。

Rats in model control group were treated with distilled water while those in silibinin group were treated with 100 mg/kg silibinin. Meanwhile, 100 mL/L ethanol and hyperalimentation feed were given for 4 weeks. After animals were killed, TG, SOD, GSH and MDA levels were measured with liver suspension.

同时继续给予100 mL/L乙醇和高营养饲料，4周后在麻醉状态下处死大鼠，取大鼠肝块进行病理观察，测定三酰甘油、超氧化物歧化酶、还原性谷胱甘肽和丙二醛水平。
