The yeast Pachysolen tannophilus was found to be capable of converting D-xylose to ethanol. Batch cultures initally containing 50 g/L D-xylose yielded 0.34 g of ethanol per gram of pentose consumed. Aerobic conditions were required for cell growth but not for ethanol production. Both alcohol formation and growth were optimum when incubation temperature was 32 degrees C, when pH was near 2.5, and when D-xylose and ethanol concentrations did not exceed 50 and 20 g/L, respectively. (Refs. 16).
