Chemicals and Bioproducts from Biomass

Recently, Biotechnology for Biofuels took the decision to widen its scope to also include articles on the biological production of chemicals and bioproducts derived from biomass and CO2. Whereas a large proportion of the articles in Biotechnology for Biofuels still deal with the pretreatment, hydrolysis and bioconversion of lignocellulosic biomass to ethanol, the journal also has published a number of interesting articles related to bio-based chemicals and other bioproducts. This retrospective thematic issue assembles recent articles since 2015 to highlight these areas of research.
