| Abstract: | The yeastTorulopsis candida NCYC 576 was found to transport acyclic polyols (D-arabinitol,L-arabinitol, ribitol, xylitol,D-mannitol,D-glucitol and erythritol) and monosaccharides (D-galactose,L-sorboseD-xylose) by an active process, reaching high intracellular concentrations, making use of four different carrier systems: (1)
high-affinity for polyols, (2) high-affinity for monosaccharides, (3) lowaffinity for both polyols and monosaccharides, and
(4) specific high-affinity for erythritol andD-ribose. |
