Saccharomyces Cerevsiae Bio-Ethanol Production, A Renewable and Sustainable Source of Energy

Today, world energy demand is based on fossil fuels, which will vanish in coming decades. Renewable energy especially biofuels has attracted great interest as solution to the current energy problem. Among available biofuel resources, bioethanol seems to be an efficient alternative source of sustainable energy. Saccharomyces cerevisiae is a well-established organism for the production of bioethanol. However, yeast cells experiences various stress conditions during the process of fermentation. The efficiency of commercial bioethanol production is hampered by the inhibitors. To overcome these stress conditions, yeast cells adopt different signal transduction pathways. In this article, author discussed various protectants, genes and pathways which can be tempered to engineer yeast strains.
