LOOP4PACK’s 1st scientific paper has been published in Process Biochemistry!

As part of Coline Perdrier's thesis, the first scientific article from the LOOP4PACK project has been published in Process Biochemistry! It is entitled "Impact of overflow vs. limitation of propionic acid on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) biosynthesis". This article investigated the impact of carbon-limiting vs. carbon-overflow conditions thanks to fed-batch cultures, with continuous or sequential feeding of propionic acid as the sole carbon source, and phosphorus deficiency conditions. In this line, the [...]

Effect of carbon source and P limiting level on microbial selection of PHA overproducers Auteurs : Laetitia Cavaillé, Sandrine Paissé, Matteo Castiello, Anne-Sophie Lepeuple, Claire Dumas, Guillermina Hernandez-Raquet, and Etienne Paul ( Polyhydroxyalkanoates (PHA) are very attractive molecules because of their biodegradability and their industrial benefits. PHA production can be done using mixed microbial cultures, which lowers production costs and environmental impacts. However, these cultures must be enriched in overproducing [...]

LOOP4PACK present at ISBP 2022

On the occasion of the 18th International Symposium on Biopolymers (ISBP) in Sion (Switzerland), Mattéo Castiello – TBI – presented his study on the “PHA production by microbial consortia selected in continuous cultures: Modeling the effect of phosphorus limitation and nitrogen deficiency". It was also an opportunity to share and discuss with the scientific community involved in the various biopolymer production sectors.

Participation in the RRB 2022 International Congress

Coline Perdrier introduced her thesis work at the RRB 2022 conference (Renewable Resources and Biorefineries) held in Bruges, Belgium, with a poster entitled "Impact of specific feeding rate of propionic acid on the structure (especially %HV) and properties of microbial P(3HB-co-3HV) copolymer”. This was an opportunity to make the LOOP4PACK project internationally known and to discover other teams working on microbial PHAs (from their biosynthesis to their use). Coline [...]
