Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate (PHA), a polymer belonging to the polyesters class that are of interest as bio-derived and biodegradable plastics. [1]

Jun 14, 2025 · PHB is a thermoplastic with a melting point of approximately 175°C. It can be melted and molded into various shapes using conventional plastic manufacturing equipment. Physically, PHB is …

PHB is produced by microorganisms (such as Ralstonia eutropha or Bacillus megaterium) apparently in response to conditions of physiological stress.

PHB is water insoluble and relatively resistant to hydrolytic degradation. This differentiates PHB from most other currently available biodegradable plastics, which are either water soluble or moisture …

Dec 15, 2017 · Recent developments in blends and composites of PHB with other polymers and fillers are discussed in terms of structure-property relationships and applications. Their contribution toward …

Polyhydroxybutyrate (PHB) is a type of biopolymer produced by certain bacteria as an energy storage compound. It is a member of the polyhydroxyalkanoate (PHA) family and serves as an intracellular …

It delves into various aspects of PHB synthesis, including fermentation methods and optimization techniques. Additionally, it examines diverse PHB-producing strains and their strain-dependent …

Sep 28, 2023 · Polyhydroxybutyrate (PHB) is a bacterial biopolymer that has begun to replace petrochemical plastics due to the present trend towards the efficient utilisation of relatively cheaper …
