Biobutanol From Microalgae

Abstract

Biobutanol is one of the promising biofuels. It can be preferred because of energy density for biofuel. But, the fermentation process for biobutanol production has less productivity efficiency due to the inhibitory effects of some compounds. The reaction has a two-step process. Firstly, butyric and acetic acids occur in the reaction. Then, acetone, butanol, and ethanol generate in the product. This process maintains by means of the acetone-butanol-ethanol (ABE) fermentation. Biobutanol can be produced via plants and plant wastes. However, these feedstocks have limitations due to their lower growth rates and productivity efficiencies for production. Due to these disadvantages, scientists have studied microalgae nowadays. They can be used for biobutanol production because of their higher growth rates and compositions. This chapter explains how to produce biobutanol from microalgae. Also, this study investigates the disruptive technological approaches from biobutanol production from microalgae and it includes the novel studies on biobutanol. © 2022 Elsevier Inc.
