Cultivation of microalgae for bioethanol production emerged as one of the potential solutions to drive green and sustainable biofuel production. Microalgae are photosynthetic microorganisms that can grow rapidly and are able to accumulate high content of carbohydrate within their cells. The carbohydrate is usually stored in the form of starch, which is easier to breakdown to simple reducing sugar compared to lignocellulosic biomass. In the present chapter, the process route to produce bioethanol from microalgae biomass is discussed, including the cultivation strategies to enhance microalgae carbohydrate productivity, biomass pre-treatment methods, hydrolysis and fermentation process.
