Abstract

Within the many possible renewable energy resources, biofuels dominate the current market. However, given the tight economic margins of the (bio)fuels sector, it is the design of overall cost-efficient processes what will determine the large scale implementation of these processes. Compared to alcohol biofuels (e.g. ethanol), the extracellular production of diesel and jet-like biofuels offers advantages in terms of product separation from the fermentation broth. However the microbial production of diesel and jetfuel-like biofuels results in a four-phase (S-L-L-G) mixture in the reactor (microbial cells, aqueous medium, lipid product and fermentation gas), which shows emulsion characteristics. Although there have been studies on the emulsion behavior of those mixtures, little emphasis has been given to a systematic study of factors relevant for large scale separation operation. Understanding the mechanisms behind emulsion formation is key for a rationale feedstock (and the pre-treatment associated to it) selection, for defining process (fermentation and product recovery) conditions and for identifying targets for synthetic biology of producing micro-organisms (e.g. robustness at low pH, high salt concentration). Thus, this proposal aims at cooperation between two research groups that can contribute to the consolidation of processes for production of biofuels. The group of Delft University is expert in bio-processes, while the group at the University of Campinas has experience in emulsions and protein-based emulsifiers. In particular, it is expected to understand the mechanisms that lead to the formation of emulsion in the fermentation process to develop a separation process efficient and inexpensive, but at the same time preserving the microbial cell viability.
