Abstract. Sugar uptake was measured with 3H-galactose and 14C-glucose. Galactose transport system was not modified by inhibitors of known translocases and did not present a saturation kinetic with high concentration of galactose. Glucose incorporation was inhibited by lasalocid (cation symport inhibitor) and increased by KCl. The kinetic parameters K M and V max were respectively 9.16 mM and 26.56 nmol/min/mg cell protein. On the basis of this study, galactose crossed through the membrane by diffusion, and glucose was incorporated by a cation symport which is regulated by K+ ions.
