## Abstract The yeast __Pachysolen tannophilus__ was found to be capable of converting Dโxylose to ethanol. Batch cultures initially containing 50 g/L Dโxylose yielded 0.34 g of ethanol per gram of pentose consumed. Aerobic conditions were required for cell growth but not for ethanol production. Bo
Production of ethanol from glucose and xylose by different Fusarium strains has been studied in shake flask cultures. The best strain was Fusarium oxysporum VTT-D-80134. The best ethanol yields were 50 % ethanol on both sugars. The fermentation time was 3 days on glucose and 6 days on xylose.
## Yeasts capable of fermenting both o-xylose and cellobiose to ethanol were screened. Of 213 species of yeasts surveyed, Kluyveromyces cellobiovorus sp. nov.. a new species belonging to genus of Kluyveromyces, was selected as the sole strain. This strain accumulated 32, 22, and 19 g/L of ethanol
