After three and half years working within LOOP4PACK project, on March 22th, Coline Perdrier successfully defended her thesis work entitled “Production of ductile materials based on P(3HB-co-3HV) with high contents of 3HV: from biosynthesis strategy with Cupriavidus necator to thermomecanical shaping process”.

The jury composed of Christelle Simon-Colin (IFREMER), Manfred Zinn (HES-SO Valais Wallis), Etienne Paul (INSA Toulouse), Estelle Grousseau (University of Montpellier) and Hélène Angellier-Coussy (University of Montpellier) was chaired by Eric Trably (INRAE). Within the time limit, she had the opportunity to present two important parts of her thesis work.
1/ the impact of propionic acid feeding strategy (overflow vs. limitation) on P(3HB-co-3HV) biosynthesis in terms of copolymer molecular structure as well as productivity and substrate conversion yield.
2/the impact of the implementation of extraction and melt processing steps on 3HV-enriched P(3HB-co-3HV) mechanical properties.
The presentation was followed by a two-hour rich discussion that allowed the emergence of relevant outlooks about P(3HB-co-3HV) production.
