Trends for the development of biomass- and CO2-based bioprocesses

The development of biomass-based technologies is seen nowadays as one of the main drivers of our society to move towards a more sustainable future with reduced greenhouse gas (GHG) emissions and a more appropriate use of natural resources.

Another promising way to reduce GHG emissions is the development of technologies for CO2 utilization. CO2 can be used as carbon source for microbial production of valuable compounds, or used directly as a greener alternative to more traditional solvents applied for biomass pretreatment. However, large-scale implementation of biomass-based and CO2-based processes still requires significant research efforts to result in robust and cost-competitive technologies.

Scientists from BCBT group at the Department of Biotechnology and Biomedicine – Technical University of Denmark have discussed some promising approaches able to advance this research area, including potential strategies for process intensification (enzymatic hydrolysis using high solid loading, simultaneous saccharification and fermentation, fermentation with downstream process integration), robust microbial strains for application in biomass-based and CO2-based bioprocesses, microbial co-cultivation systems and greener technologies for lignocellulosic biomass fractionation, among others.

This study was published in the journal Renewable and Sustainable Energy Reviews and is the core of the project BiobaseDK – Biobased Solutions to Promote Sustainability, supported by the Novo Nordisk Foundation and coordinated by Prof. Solange I. Mussatto. Giuliano Dragone, Celina K. Yamakawa and Lucas van der Maas are co-authors of the study.
