Xylose entry to the PPP pathway and xylose metabolizing capacities of different ascomycetes.

A) The schematic presentation of conserved genes encoding enzymatic activities for the xylose entry into the PPP pathway in ascomycetes. C. a for Candida albicans, S. c for Saccharomyces cerevisiae, and S. s for Schefferomyces stipitis. B) Growth of C. albicans (SC5314), S. stipitis (CBS6054) and S. cerevisiae (BY4741) in SC with 2% xylose or 0.5% xylulose. Strains were grown aerobically at 30°C and the optical density measured over a period of six days, n=3.
