Cumulative sugar utilization (grams of glucose consumed per liter of MNS) of selected Saccharomyces cerevisiae isolates and reference yeast strains. Strains were incubated at 40°C in MNS medium with 100 g/l glucose and 50 g/l xylose. All experiments were conducted in triplicate, with the relative standard error always being less than 5% (not reported).
