RESUMO
To investigate the role of xylose uptake in xylose metabolism in yeasts, we isolated a series of mutated strains of the yeast Pichia heedii which are defective in xylose utilization. Four of these demonstrated defects in xylose uptake. Overlaps between the functional or regulatory mechanisms for glucose and xylose uptake may exist in this yeast since some of the mutants defective in xylose uptake were also defective in glucose transport. None of the mutants were defective in xylose reductase or xylitol dehydrogenase activities.
