Summary
The selected yeast strains were examined for their ability to grow, to retain cell viability and to ferment diluted sugar cane juice (15 % total sugar, w/v) to ethanol at 40°C. The degree of agitation (aeration) affects the thermotolerance while the method used for isolation of the strains appears to have no significant effect. The yeast isolated are aerobically fermentative with increased levels of fermentation and growth resulting from agitation (aeration), the exact level of these increases being dependent on the strain used.
