Saccharomyces cerevisiae Bio-Ethanol Production as an Alternative Source of Sustainable Energy Ethanol Production using Saccharomyces cerevisiae

Current world energy demand is based on fossil fuels, which will vanish in coming decades. Renewable energy especially biofuels has attracted great interest as solutions to the current energy problem. Among available biofuel resources, bioethanol seems to be an efficient alternative thus, Saccharomyces cerevisiae a well-established organism for bioethanol production. However, during fermentation process, yeast cells experience various stress conditions and inhibitors hampering its efficacy for commercial bioethanol production. To overcome these yeast cells, adopt different signal transduction pathways. In this review, common and least explored carbon feedstock which can be readily converted into bioethanol are highlighted. The various protectants, genes, and pathways which can be tempered to engineer yeast strains are discussed. Thus, we have suggested strategies to utilize this lucrative alternative for sustainable bioethanol production.
