Molasses has a high sugar content and potentially good to be used as a fermentation substrate in the production of ethanol. The main purpose of this study is to compared the ethanol yield between free and immobilized on calcium alginate as the agent of fermentation. The fermentation of molasses was carried out directly using yeast isolate K2 which was free and immobilized on calcium alginate. Isolate K2 was tested physiologically first to determine the character of its tolerance to NaCl, pH, and molasses. The physiological character of isolate K2 showed its ability to grow at the limit of 12% NaCl, pH 3-6, and 25% molasses concentration at 30°C. The highest ethanol content was 1.96% from 25% molasses concentration with 24 hours fermentation using immobilized K2 isolate while the lowest ethanol content was 0.42% from 24 hours fermentation time using free yeast. Substantially, it can be concluded that the immobilization of K2 isolate in calcium alginate has the potential to increase the production of ethanol from molasses. [ABSTRACT FROM AUTHOR] |
