LipoDrivE's research

Last changed: 07 October 2019

Oleaginous yeasts can convert carbohydrates into fatty acids at the highest known specific rates and the fatty acid content can exceed half of the total biomass in the cell. Carbohydrates, in the form of lignocellulose, is regarded as the main resource for a future fossil free renewable bio-based economy.

Residues and waste material (pentoses, extractives) refining to high value products must be improved to make lignocellulosic fuel production economical and resource efficient.

In this project, we will use yeasts to convert the hemicellulose fraction of pretreated lignocellulose to produce fatty acids. The cellulose fraction can proceed to regular ethanol fermentation and the fatty acids can be processed to biodiesel while we will determine the fatty acids nutritional potential as a fish feed and food.

Residues will be investigated as a substrate for biogas production and final residues will be evaluated as a biofertilizer. The fatty acid production thereby couples the material and energy flows of sustainable fuel, feed, food and biomass production and gives us a unique possibility to use systems analysis and LCA to evaluate the energy efficiency, global warming effect, nutrient recycling and economic performance of different process scenarios.

Specifically, we are investigating

  • Cultivation conditions
  • Cell physiology
  • Assay different substrates and species/ strains

This is done in order to find optimal fatty acid production conditions with improved nutritional value.
