Researchers at Chalmers University of Technology, Sweden, have identified two main challenges for renewable biofuel production from cheap sources. Firstly, lowering the cost of developing microbial cell factories, and secondly, establishing more efficient methods for hydrolysis of biomass to sugars for fermentation. Their study was recently published in the journal Nature Energy.
Researchers at Chalmers University of Technology, Sweden, have identified two main challenges for renewable biofuel production from cheap sources. Firstly, lowering the cost of developing microbial cell factories, and secondly, establishing more efficient methods for hydrolysis of biomass to sugars for fermentation. Their study was recently published in the journal Nature Energy.
The study, by Professor Jens Nielsen, Yongjin Zhou and Eduard Kerkhoven, from the Division of Systems and Synthetic Biology, evaluates the barriers that need to be overcome to make biomass-derived hydrocarbons a real alternative to fossil fuels.
“Our study is of particular interest for decision makers and research funders, as it highlights recent advances and the potential in the field of biofuels. It also identifies where more research is required. This can help to prioritise what research should be funded,” says Eduard Kerkhoven.
It is technically already possible to produce biofuels from renewable resources by using microbes such as yeast and bacteria as tiny cell factories. However, in order to compete with fossil-derived fuels, the process has to become much more efficient. But improving the efficiency of the microbial cell factories is an expensive and time-consuming process, so speeding-up the cell factory development is therefore one of the main barriers.
