Jeffries, T W

In a survey of 35 organisms, predominantly yeasts, about 40% were capable of fermenting xylulose to ethanol. Two species, Candida tropicalis and Schizosaccharomyces pombe, did so at good rates and without an initial lag. Saccharomyces cerevisiae strains that fermented glucose rapidly fermented xylulose at a slower rate. Ten yeasts and three strains of the bacterium Zymomonas mobilis were weak or negative for xylulose, even though they fermented glucose under the conditions employed. C. tropicalis was able to form 1.0 M ethanol from 1.0 M xylose if the fermentation broth was recycled over immobilized xylose isomerase.
