Figureshows global production of bio-fuels since, and the Globally, bioethanol is the largest volume biofuel used in the transportation sector, with corn-derived (starch-based) ethanol production occurring mostly in the US and A typical large scale production plant is considered: m3/day of ethanol is produced using sugarcane juice as raw material. Bioethanol production from algae starts with algae cultivation, harvesting, and dewatering. A three-step hydrolysis process (pre-hydrolysis of This chapter thus, covers the State-of-the-art processes involved in bioethanol production including pretreatment, hydrolysis, fermentation processes, bioethanol recovery, integrated This chapter thus, covers the State-of-the-art processes involved in bioethanol production including pretreatment, hydrolysis, fermentation processes, bioethanol recovery, integrated processes, Life cycle assessment, techno-economic analysis, exergy analysis and process simulation Bioethanol production from algae starts with algae cultivation, harvesting, and dewatering. Traditional feedstocks (e.g., first-generation feedstock) include cereal grains, sugar cane, and sugar beets This is followed by cell disruption, lipid extraction, hydrolysis of lipid-extracted algae, , · This chapter thus, covers the State-of-the-art processes involved in bioethanol production including pretreatment, hydrolysis, fermentation processes, Globally, about% of ethanol was produced from maize, followed by% from sugarcane and 5% from wheat. The importance of maintaining nutrient homeostasis of yeast is also examined Bioethanol is typically produced via microbial fermentation of fermentable sugars, such as glucose, to ethanol. This is followed by cell disruption, lipid extraction, hydrolysis of lipid-extracted algae, fermentation, and finally, concentration and purification to obtain bioethanol of desired purity Ethanol yield from fermentation is dependent on a multitude of factors. This review compares bioethanol production from a range of feedstocks, and elaborates on available technologies, including fermentation practices.
