Purpose and goal
The project’s main purpose is to address the limitations of microbial oils-based biodiesel, focusing particularly in carbon source cost, yeast productivity, and lipid extraction efficiency. This will contribute to a decrease in biodiesel production costs and increase its competitiveness. The specific goals are: 1) To develop a robust yeast strain for the production of lipids from lignocellulosic residues. 2) To increase the lipid accumulation and titre through optimization of the growth conditions. 3) To develop a quicker and cleaner in situ transesterification process.
Expected results and effects
The expected results include improved yeast strains with potential for industrial application, and new methodologies for cell propagation and lipid extraction. The overall increase in productivity and process efficiency, and decrease in raw materials and energy costs will significantly contribute to reduce the production costs. In conclusion, the project will provide a cost competitive microbial biodiesel based on non-food crops, and offer a green and sustainable alternative for the European fuel market.
Planned approach and implementation
This project has been divided into three work packages to address the research goals (WP1-3), and one work package dedicated to the results dissemination and exploitation (WP4). In WP1 improved strains will be developed (20 months), while in WP2 cell propagation and lipid accumulation will be optimized (19 months), and finally in WP3 microwave-assisted biodiesel production will be implemented (18 months). Each of the work packages aim to meet the respective objective.
