Converting carbohydrates to biodiesel

Last changed: 08 April 2022

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 derived from lignocellulose, are regarded as the main resource for a future fossil free renewable bio-based economy.

This project investigates the conversion of those carbohydrates to biodiesel or lipids for fish feeding, using oleaginous yeasts such as Lipomyces starkeyi or Rhodotorula glutinis.

This projects is part of the LipoDrivE project.
