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 ...

Polyhydroxybutyrate synthesis in transgenic flax

Journal of Biotechnology, 2004
Flax (Linum usitatissimum L.) is an annual plant species widely cultivated in temperate climates for bast fibres and linseed oil. Apart from traditional textile use, the fibres are fast becoming an integral part of new composite materials utilized in automobile and constructive industry.

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.

New Biodegradable Polyhydroxybutyrate/Layered Silicate Nanocomposites

Biomacromolecules, 2007
Poly(hydroxybutyrate) (PHB)/layered silicate nanocomposites were prepared via melt extrusion. The nanostructure, as observed from wide-angle X-ray diffraction and transmission electron microscopy, indicates intercalated hybrids. The extent of intercalation depends on the amount of silicate and the nature of organic modifier present in the layered ...

Thermophysical and Mechanical Properties of β-Tricalcium Phosphate Reinforced Polyhydroxybutyrate and Polyhydroxybutyrate-Co-Hydroxyvalerate Composites

Key Engineering Materials, 2007
Two series of bioactive and biodegradable composite materials consisting of particulate β-tricalcium phosphate (β-TCP) and polyhydroxybutyrate (PHB) and its copolymer polyhydroxybutyrate-co-hydroxyvalerate (PHBV) were produced and investigated for bone tissue repair.
