Impact of fermentation residues on the thermal, structural, and rheological pro...
Hilliou, L.; Machado, Diogo; Oliveira, Catarina S. S.; Gouveia, Ana R.; Reis, Maria A. M.; Campanari, Sabrina; Villano, Marianna; Majone, MauroThe effects of recovered residues on the characteristics of polyhydroxy(butyrate-co-valerate) (PHBV) produced from mixed microbial cultures (MMCs) fed with cheese whey, olive oil mill wastewater, or a synthetic mixture of acetic and propionic acid were investigated. The different types of MMC PHBVs were extracted and purified with different downstream routes; this enabled the recovery of polymers with different...

Hilliou, L.; Machado, Diogo; Covas, J. A.; Oliveira, Catarina S. S.; Duque, F.; Reis, Maria A. M.; Campanari, Sabrina; Villano, Mariana; Majone, MauroIn addition to their poor processability with conventional plastic processing techniquesi , polyhydroxyalkanoates (PHA) are expensive when compared to other plastics. PHA recovery and purification take a strong share on the final product cost, but the impact of fermentation residues on PHA properties relevant for processing and final product properties is not sufficiently documented in the literature. Here we r...

Cunha, Mara; Oliveira, Catarina S. S.; Duque, F.; Reis, Maria A. M.; Campanari, Sabrina; Villano, Mariana; Majone, Mauro; Covas, J. A.; Hilliou, L.Polyhydroxyalkanoates (PHA) have two major assets which make them promising polymers for future packaging application to reduce the ecological footprint of plastics: they are fully biodegradable and bio-based. However, PHA are not yet used in plastic bags, pouches or flat thin films because they are still 10 times more expensive than conventional plastics used for such application, and most of all, because they...
