Microorganisms, Journal Year: 2024, Volume and Issue: 12(10), P. 2028 - 2028

Published: Oct. 8, 2024

The search for alternatives to petrochemical plastics has intensified, with increasing attention being directed toward bio-based polymers (bioplastics), which are considered healthier and more environmentally friendly options. In this review, a comprehensive overview of polyhydroxyalkanoates (PHAs) is provided, including their characterization, applications, the mechanisms underlying biosynthesis. PHAs natural polyesters produced by wide range prokaryotic some eukaryotic organisms, positioning them as significant widely studied type bioplastic. Various strategies production from agroindustrial waste, such cacao shells, cheese whey, wine, wood, beet molasses, reviewed, emphasizing potential sustainable feedstocks. Industrial processes PHAs, complexities associated extraction purification, also examined. Although use waste materials offers promise in reducing costs environmental impact, challenges remain optimizing these enhance efficiency cost-effectiveness. need continued research development improve sustainability economic viability PHA emphasized, viable eco-friendly alternative conventional petroleum-based plastics.

Enhancing the Potential of PHAs in Tissue Engineering Applications: A Review of Chemical Modification Methods

Materials, Journal Year: 2024, Volume and Issue: 17(23), P. 5829 - 5829

Published: Nov. 27, 2024

Polyhydroxyalkanoates (PHAs) are a family of polyesters produced by many microbial species. These naturally occurring polymers widely used in tissue engineering because their vivo degradability and excellent biocompatibility. The best studied among them is poly(3-hydroxybutyrate) (PHB) its copolymer with 3-hydroxyvaleric acid (PHBV). Despite superior properties, PHB PHBV suffer from high crystallinity, poor mechanical slow resorption rate, inherent hydrophobicity. Not only hydrophobic, but almost all members the PHA struggle this characteristic. One can overcome limitations modifying bulk or surface chemical composition. Therefore, researchers have put much effort into developing methods for modification PHAs. This paper explores rarely addressed topic review articles-chemical structure to enhance suitability as biomaterials applications. Different strategies improving wettability properties scaffolds discussed review. PHAs that important applications also discussed.
