Polyhydroxybutyrate (PHB): microbial synthesis and waste valorisation for sustainable bioplastics

Discover Applied Sciences
Polyhydroxybutyrate (PHB), a biocompatible and biodegradable polymer, is an inevitable alternative source for the replacement of conventional plastics. PHB is an integral unit of various composite materials for its superior mechanical properties.

Phasin PhaP1 is involved in polyhydroxybutyrate granules morphology and in controlling early biopolymer accumulation in Azospirillum brasilense Sp7

AMB Express, 2019
Phasins are amphiphilic proteins involved in the regulation of the number and size of polyhydroxybutyrate (PHB) granules. The plant growth promoting bacterium Azospirillum brasilense Sp7 accumulates high quantities of bioplastic PHB as carbon and energy ...

PRODUCTION AND CHARACTERIZATION OF POLYHYDROXYBUTYRATE (PHB): A BIODEGRADABLE POLYMER

Environmental pollution caused by synthetic plastics has become a major global concern. Biodegradable polymers such as Polyhydroxybutyrate (PHB), produced by microorganisms, offer an eco‑friendly alternative to conventional plastics. The present research paper focuses on the microbial production of PHB, its extraction, and characterization.

Effect of Lauric Acid on the Thermal and Mechanical Properties of Polyhydroxybutyrate (PHB)/Starch Composite Biofilms

, 2020
Polyhydroxybutyrate (PHB) is a biopolymer of natural origin, one of the suitable alternatives for synthetic plastics. However, pure PHB has a high production cost, is relatively brittle, and has poor processability, hence its limited application ...
