底酵母

The relative activity of a lipase from Candida valida Z6 was studied in hydrolysis of simple esters,fatty acid glycerides and lipidse.

通过与一种不同来源的脂肪酶作比较，研究了粗状假丝酵母诱变株Z6产脂肪酶水解不同底物的相对酶活，包括对低级酯、脂肪酸甘油酯和天然油脂的水解。

Asymmetric reduction of prochiral ketone to these chiral alcohol s by active microbe cells is one of the most promising routes.

以4-氯苯乙酮为苯环上含卤素的芳香酮的模型底物，研究了活性酵母细胞在水相体系中催化该类芳香酮不对称还原合成相应手性醇的反应特性。

The asymmetric reduction of prochiral P-oxo ester, aromatic ketone and aliphatic ketone to its corresponding chiral alcohol by yeast cells were studied respectively in this work when ethyl 4-chloro-3-oxobutyrate, acetophenone and 2-octanone were as the model substrates.

本文以4-氯乙酰乙酸乙酯、苯乙酮和2-辛酮分别为β-羰基酯、芳香酮和脂肪酮的模型底物，研究了利用活性酵母细胞催化这三类前手性酮不对称还原合成相应手性醇的反应特性。

The washing experiment of soil contaminated by petroleum alkane was performed with two kinds of biosurfactants in laboratory. The results showed that biosurfactant would enhance on removal of residual alkane in soil, after washing with 20 pore volume solution the removal rate with BS-UC and MELs were three times and twice as that of water, respectively.

在实验室内对南极假丝酵母产生的两种生物表面活性剂进行了石油烃类污染土壤的冲洗实验，结果表明，经过大约20个孔隙体积的冲洗，BS-UC溶液的除油率为清水的三倍，MEL溶液为清水的两倍，这表明该生物表面活性剂能够加速土壤残油的去除，而来自污染底物的生物表面活性剂更具有优越性。

As the concentration of substrate increased, the e.e.
