Increasing alcohol yield by selected yeast fermentation of sweet sorghum. I. Evaluation of yeast strains for ethanol production
A study was conducted for the purpose of evaluating and selecting yeast strains for their ability to produce ethanol using sweet sorghum juice as the substrate. Stalks of sweet sorghum were obtained by cutting off the tops and stripping away the leaves. Fermentation media were prepared by diluting or adding dextrose to the sorghum juice to give a sugar concentration of either 10% (w/v) or 20% (w/v). All yeast strains were first tested in 10% (w/v) total sugar medium. Those strains showing more than 90% sugar conversion efficiency were further tested in 20% (w/v) total sugar medium. Active cultures for inoculation were prepared by growing the yeast strains on the fermentation medium (10% (w/v) total sugar) for 24 h. Then the cultures were added to the fermentation media at a rate of 2%.
