Preparation of alkyl (R)-(−)-3-hydroxybutyrate by acidic alcoholysis of poly-(R)-(−)-3-hydroxybutyrate

open access: yesEnzyme and Microbial Technology, 2000
An efficient method for the preparation of optically active alkyl (R)-(-)-3-hydroxybutyrates by chemical depolymerization of biopolymer, poly-(R)-(-)-(3-hydroxybutyrate), was established. This method consists of simple recovery of poly-(R)-(-)-(3-hydroxybutyrate) from bacterial cells followed by acidic alcoholysis. When poly-(R)-(-)-(3-hydroxybutyrate)

Comparison of acellular and cellular bioactivity of poly 3-hydroxybutyrate/hydroxyapatite nanocomposite and poly 3-hydroxybutyrate scaffolds

open access: yesBiotechnology and Bioprocess Engineering, 2013
Nanocomposites have recently been identified as a useful scaffolding material in tissue engineering applications. Poly (3-hydroxybutyrate)/hydroxyapatite nanoparticles (P3HB)/(nHA) porous scaffolds were successfully fabricated through a solvent casting and particulate leaching technique.

Production and Characterization of Melt-Spun Poly(3-hydroxybutyrate)/Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) Blend Monofilaments

open access: yesACS Omega
We investigated the melt-spinning potential of a poly(3-hydroxybutyrate)/poly(3-hydroxybutyrate-co-4-hydroxybutyrate) blend using a piston spinning machine with two different spinneret diameters (0.2 and 0.5 mm).

Synthesis of Poly(3-hydroxybutyrate) by Immobilized Poly(3-hydroxybutyrate) Synthase [PDF]

open access: yesPolymer Journal, 2003
At present, biodegradable and biocompatible polymers are being widely sought by materials industries, and poly(3-hydroxyalkanoate) (PHA) appears to be one of the most promising material sources of such polymers. Poly(3-hydroxybutyrate) (PHB) is a typical PHA and has been investigated in detail.

Microbial degradation of poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in soils [PDF]

open access: yesApplied and Environmental Microbiology, 1993
The microbial degradation of tensile test pieces made of poly(3-hydroxybutyrate) [P(3HB)] or a copolymer of 90% 3-hydroxybutyric acid and 10% 3-hydroxyvaleric acid was studied in soils incubated at a constant temperature of 15, 28, or 40 degrees C for up to 200 days.

Poly(3-hydroxybutyrate) Nanocomposites with Cellulose Nanocrystals

open access: yesPolymers, 2022
Poly(3-hydroxybutyrate) (PHB) is one of the most promising substitutes for the petroleum-based polymers used in the packaging and biomedical fields due to its biodegradability, biocompatibility, good stiffness, and strength, along with its good gas-barrier properties. One route to overcome some of the PHB’s weaknesses, such as its slow crystallization,

Recent Advances in the Use of Polyhydroyalkanoates in Biomedicine

open access: yesBioengineering, 2019
Polyhydroxyalkanoates (PHAs), a family of natural biopolyesters, are widely used in many applications, especially in biomedicine. Since they are produced by a variety of microorganisms, they possess special properties that synthetic polyesters do not ...
