Cyanobacterial Polyhydroxybutyrate (PHB): Screening, Optimization and Characterization. [PDF]

PLoS One, 2016
In modern life petroleum-based plastic has become indispensable due to its frequent use as an easily available and a low cost packaging and moulding material. However, its rapidly growing use is causing aquatic and terrestrial pollution. Under these circumstances, research and development for biodegradable plastic (bioplastics) is inevitable ...

PHB into PHB: Recycling of polyhydroxybutyrate by a tandem “thermolytic distillation-microbial fermentation” process [PDF]

Resources, Conservation and Recycling, 2022
Abstract The recycling of polyhydroxybutyrate (PHB) via depolymerization-polymerization is here proposed and assessed for the first time. Effective depolymerization of PHB to crotonic acid through a thermolytic distillation at mild conditions (170 °C and 150 mbar), and without the need of any catalyst, gives a crotonic acid-enriched condensate (94 ...

Embolization with Polyhydroxybutyrate (PHB) Microspheres: In-Vivo Studies

Journal of Bioactive and Compatible Polymers, 1999
In this study polyhydroxybutyrate (PHB), produced by a methanol-utilizing bacteria, was used to prepare microspheres in the 120-200 μm size range for embolization. A solvent evaporation technique was utilized to obtain microspheres in which methylene chloride, distilled water and polyvinyl alcohol were used as the solvent, precipitation medium and ...

Finding a Benign Plasticizer to Enhance the Microbial Degradation of Polyhydroxybutyrate (PHB) Evaluated by PHB Degrader Microbulbifer sp. SOL66. [PDF]

Polymers (Basel), 2022
As a biodegradable plastic, polyhydroxybutyrate (PHB) has relatively poor mechanical properties, preventing its wider use. Various plasticizers have been studied to improve the mechanical properties of PHB; however, due to the slow degradation speed in ...
