Biomanufacturing of renewable liquid fuels, such as ethanol and n-butanol, from biomass is a critical direction for carbon neutrality. However, in contrast to the mature bioalcohols industry that based on the first-generation sugar and starch-containing raw ingredients, there is still a significant gap between the scale of ambition and commercialization in the second- and third- generations bioalcohols production from abundant lignocellulose and industrial waste gas. In recent years, increasingly more studies have emerged, which are focusing on the development of alternative techniques for maximizing the environmental and economics of the bioalcohols production from raw biomass feedstocks.
This special collection of Biotechnology for Biofuels aims to gather high-quality research outcomes on the recent advances in biorefinery for bioalcohols production. Specifically, the collection will cover the following topics (but are not limited to): the fractionation of lignocellulose, the development of renewable sugars platform, the construction of bioalcohols producing strain, the strengthening of fermentation and downstream separation processes, the waste streams management and valorization, and the upgrading of the bioalcohols. Special consideration will be given to studies investigating the “zero carbon” or “carbon negative” biorefinery processes for bioalcohols. Research focused on the supply chain of biomass feedstocks, the techno-economic analysis, and life-cycle assessment are also encouraged.
