Biodegradation Studies of Polyhydroxybutyrate and Polyhydroxybutyrate-Co-Polyhydroxyvalerate Films in Soil

International Journal of Molecular Sciences, 2023
Due to increased environmental pressures, significant research has focused on finding suitable biodegradable plastics to replace ubiquitous petrochemical-derived polymers. Polyhydroxyalkanoates (PHAs) are a class of polymers that can be synthesized by microorganisms and are biodegradable, making them suitable candidates.

In Vitro and in Vivo Evaluation of Polyhydroxybutyrate and of Polyhydroxybutyrate Reinforced With Hydroxyapatite

Biomaterials, 1991
Polyhydroxybutyrate (PHB) is a polyester made by many microorganisms under conditions of nitrogen deficiency, and is produced commercially in bulk by biotechnology. It has been suggested that PHB-based materials (copolymers and composites) could be suitable for medical applications and may be biodegradable.

Metabolic modeling of polyhydroxybutyrate biosynthesis

Biotechnology and Bioengineering, 1998
A mathematical model describing intracellular polyhydroxybutyrate (PHB) synthesis in Alcaligenes eutrophus has been constructed. The model allows investigation of issues such as the existence of rate-limiting enzymatic steps, possible regulatory mechanisms in PHB synthesis, and the effects different types of rate expressions have on model behavior ...

Fabrication and Characterisation of Polymer and Composite Scaffolds Based on Polyhydroxybutyrate and Polyhydroxybutyrate-Co-Hydroxyvalerate

Key Engineering Materials, 2007
This paper reports the fabrication and characterization of three-dimensional, highly porous polyhydroxybutyrate (PHB), polyhydroxybutyrate-co-valerate (PHBV) and composite scaffolds made by the emulsion freezing / freezing-drying technique. Freeze-drying of the polymer/solvent/ water phase emulsions produced hard and tough scaffolds with interconnected

Polyhydroxybutyrate in Azospirillum brasilense

2015
Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate produced by several bacteria as carbon storage and reductive equivalents sink. The production of PHB has been reported for several plant-associated bacteria, and especially in Azospirillum brasilense, the production of PHB has been associated as a factor for stress endurance.

On Morphology of Polyhydroxybutyrate

2013
It is in process installed, that to growth of polarity of dissolvent there is a perfection of a crystal structure and decrease of a share of amorphous phase polyhydroxybutyrate (PHB). It is shown, that a share of a defective crystal phase in films PHB directly proportional to magnitude of cohesive energy of dissolvent.
