Conversion of D-xylose to ethanol by the yeast Pachysolen tannophilus [Use of fermentation process for the conversion of plant biomass into fuel]

The yeast Pachysolen tannophilus was found to be capable of converting D‐xylose to ethanol. Batch cultures initially 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 format...

Description
Summary:The yeast Pachysolen tannophilus was found to be capable of converting D‐xylose to ethanol. Batch cultures initially 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°C, when pH was near 2.5, and when D‐xylose and ethanol concentrations did not exceed 50 and 20 g/L, respectively.
