Uptake of galactose and lactose by Kluyveromyces lactis: biochemical characteristics and attempted genetical analysis.
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.
