WG5: Bioproducts generation from the carboxylate platform by non-conventional yeasts

In addition to sugars, the so-called Volatile Fatty Acids (VFAs) are considered low-cost carbon sources for the production of bio-based compounds. These VFAs are obtained during the first stages of the anaerobic digestion process when biogas production is limited. The capacity of several non-conventional yeasts to assimilate a broad range of substrates make these microorganisms an exceptional choice for the conversion of VFAs into a vast number of bioproducts. VFAs obtained from low-cost raw materials in WG2 (e.g. agri-food residues, lignocellulose, etc.) will be used as feedstock for both naturally occurring and recombinant strains to produce industrially relevant bioproducts. Furthermore, particular traits of the non-conventional yeasts (e.g. tolerance to acid stress) will be highly desired and an important aspect to consider.
