Summary
66 different yeast strains were screened for glucose, xylose and xylulose fermentation in shake flask cultures. None of the tested yeasts was able to grow or produce significant amounts of ethanol on xylose anaerobically. The best ethanol yields from xylulose were obtained with a wine yeast, two distillery yeasts, and a strain of Saccharomyces uvarum. The best conversion of xylulose to ethanol obtained was 76 % of the theoretical yield. The optimal temperature was 30°C.
