A recent report from the University of Perugia in Italy discusses the potential use of Cupriavidus necator, a type of Gram-Negative Bacteria, for the production of biodegradable polymers for food packaging. The researchers found that Cupriavidus necator DSM 545 is capable of intracellularly accumulating Poly(3-hydroxybutyrate) (PHB), a bio-polyester, under stress conditions. They identified optimal conditions for maximizing PHB production using natural media derived from lignocellulosic residues of cardoon. The study also found that PHB films performed similarly to conventional pre-packaging materials in preserving ready-to-eat products. [Extracted from the article]
