Selection of yeast able to produce ethanol from glucose at 40/sup 0/C

Journal Article:

Abstract

A total of 55 yeast strains selected from 7 genera known to ferment carbohydrates to ethanol were screened for their ability to ferment glucose to ethanol in shaken flask culture at 37/sup 0/, 40/sup 0/ and 45/sup 0/C. Yields of more than 50% of the theoretical maximum were obtained with 28 strains at 37/sup 0/C, but only 12 at 40/sup 0/C. Only 6 could grow at 45/sup 0/C, but they produced poor yields. In general Kluyveromyces strains were more thermotolerant than Saccharomyces and Candida strains, but Saccharomyces strains produced higher ethanol yields. The 8 strains with the highest yields at 40/sup 0/C were evaluated in batch fermentations. Three of these, two Saccharomyces and one Candida, were able to meet minimum commercial targets set at 8% (v/v) ethanol from 14% (w/v) glucose at 40/sup 0/C.
