Abstract

Study of the lactose and galactose transport systems in Kluyveromyces lactis has shown that lactose uptake is by active transport. The transport system is under monogenic control and is inducible. Galactose uptake is also by active transport but the system is controlled by two genes which, in the four strains we studied, are present only in K. lactis CBS 2359. Galactose uptake in the other K. lactis strains is by a simple diffusion process.

摘要

对乳酸克鲁维酵母中乳糖和半乳糖转运系统的研究表明，乳糖的摄取是通过主动运输进行的。该转运系统受单基因控制且可诱导。半乳糖的摄取也是通过主动运输，但该系统由两个基因控制，在我们研究的四个菌株中，这两个基因仅存在于乳酸克鲁维酵母CBS 2359中。其他乳酸克鲁维酵母菌株中半乳糖的摄取是通过简单扩散过程进行的。
