Naturally coloured poly(3‐hydroxybutyrate)

Coloration Technology
Abstract This study reports an innovative approach for producing intrinsically coloured poly(3‐hydroxybutyrate) [P(3HB)] films by incorporating natural dyes—turmeric, paprika, annatto, beetroot and hibiscus—directly into the fermentation medium of Ralstonia solanacearum RS ...

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

Biotechnology 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.

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

Polymer 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.

Effect of 3-Hydroxyvalerate Content on Thermal, Mechanical, and Rheological Properties of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Biopolymers Produced from Fermented Dairy Manure

Polymers, 2022
Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with various 3-hydroxyvalerate (3HV) contents biosynthesized by mixed microbial consortia (MMC) fed fermented dairy manure at the large-scale level was assessed over a 3-month period.

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

Applied 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.

Effect of Different Plasticizers on Thermal, Crystalline, and Permeability Properties of Poly(3–hydroxybutyrate–co−3–hydroxyhexanoate) Films

Polymers, 2022
Poly(3−hydroxybutyrate−co−3−hydroxyhexanoate) (PHBH) films were prepared using a cast film technique. Dioxane was chosen over other polymer solvents as it resulted in homogenous films with better morphology.

In silico Assessment of Pharmacological Profile of Low Molecular Weight Oligo-Hydroxyalkanoates

Frontiers in Bioengineering and Biotechnology, 2020
Polyhydroxyalkanoates (PHAs) are a large class of polyesters that are biosynthesized by microorganisms at large molecular weights (Mw > 80 kDa) and have a great potential for medical applications because of their recognized biocompatibility.

Slow-Release Nitrogen Fertilizers with Biodegradable Poly(3-hydroxybutyrate) Coating: Their Effect on the Growth of Maize and the Dynamics of N Release in Soil

Polymers, 2022
Fertilizers play an essential role in agriculture due to the rising food demand. However, high input fertilizer concentration and the non-controlled leaching of nutrients cause an unwanted increase in reactive, unassimilated nitrogen and induce ...

Metabolic engineering of Escherichia coli for the synthesis of polyhydroxyalkanoates using acetate as a main carbon source

Microbial Cell Factories, 2018
Background High production cost of bioplastics polyhydroxyalkanoates (PHA) is a major obstacle to replace traditional petro-based plastics. To address the challenges, strategies towards upstream metabolic engineering and downstream fermentation ...
