PRODUCTION OF BIOFUEL FROM SUGARCANE BAGASSE WASTES USING Saccharomyces cerevisiae
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
The dry pulpy fibrous residue that remains after crush of sugarcane stalks is called Bagasse. It is Agroindustrial solid wastes which accumulated each day, causing big environmental problems. Saccharomyces cerevisiae is a unicellular fungus and has an interesting role in bioethanol production. In this study, two isolates of S. cerevisiae were used for bioethanol production from bagasse. In this study, Sugar cane bagasse were collected, hydrolyzed with concentrated HCl and used as a main carbon source (30 g/l). The growth curves of the two tested strains of S. cerevisiae were the same. The effect of temperature and pH levels on the growth, carbohydrates yields, and mainly bioethanol productivity from sugarcane wastes was studied for both Saccharomyces strains. The best conditions for bioethanol productivity was in fermentation medium after 3 days of growth at pH 6 and 30°C. In conclusion, Saccharomyces can be used for bioethanol production with the lowest possible costs from environmental wastes.
