PolyHydroxyButyrate (PHB)
PolyHydroxyButyrate (PHB) is a natural polyester produced by some bacteria. This biodegradable polymer is considered a sustainable alternative to petroleum-based plastics. PHB has found wide application in various industries due to its unique properties such as biocompatibility, biodegradability and good mechanical properties.
PHB Structure and Production
PHB is composed of repeating units of 3-hydroxybutyrate. This polymer is produced by bacteria as an energy storage source. When bacteria are exposed to unfavorable conditions, they store PHB as an energy source.
PHB Applications
Medical:
Pharmaceutical: Used in the manufacture of tissue engineering scaffolds, microspheres and nanoparticles for targeted drug delivery.
Surgery: Used in absorbable sutures, medical implants and wound dressings.
Medical implants: Used in the manufacture of cardiac stents and tissue engineering scaffolds.
Packaging: Manufacture of biodegradable garbage bags, food packaging films and food coatings.
Agriculture: Manufacture of seed coatings and controlled fertilizers.
Textile industries: Manufacture of synthetic fibers and yarns.
3D printing: Used as a raw material in 3D printing to manufacture various parts.
