Simultaneous fermentation of D-xylose and glucose byCandida shehatae

Summary Mixtures of xylose and glucose were anaerobically fermented with the yeastCandida shehatae. Cells previously grown aerobically on glucose fermented glucose and xylose sequentially. Cells grown aerobically on xylose fermented glucose and xylose simultaneously, with no lag in xylose consumption. The best results were obtained with cells grown aerobically on xylose and inoculated into a 7525 mixture. 25 g/L of ethanol and 25 g/L of xylitol were obtained from 120 g/L of carbohydrates within 50 hours.
