VIVALDI workshop “Transforming Waste into Resources: Yeast Fermentation for Circular Bioproduction”

On 14 February 2025, the VIVALDI consortium held a webinar dedicated to innovative yeast-based solutions for turning CO₂-derived methanol, formic acid, and cotton waste into valuable organic acids and biobased materials.

The webinar explored the use of different yeast strains, namely Pichia pastoris (Komagataella phaffii) and Saccharomyces cerevisiae, showcasing their unique characteristics and potential applications.

-  Dr. Pau Ferrer (Universitat Autònoma de Barcelona) discussed fermentation strategies to produce organic acids, bioprocess intensification, and the co-utilization of methanol and formic acid to produce 3-hydroxypropionic acid.

-  Dr. Simone Bachleitner (BOKU) highlighted the opportunities and challenges to produce lactic and itaconic acid from methanol and showcased how low pH fermentation can impact process sustainability.

-  Dr. Valeria Mapelli (Università degli Studi di MilanoBicocca) presented the up-cycling and valorization of cotton waste via yeast engineering and fermentation.
