A Forward-Design Approach to Increase the Production of Poly-3-Hydroxybutyrate in Genetically Engineered Escherichia coli [PDF]

, 2015
Biopolymers, such as poly-3-hydroxybutyrate (P(3HB)) are produced as a carbon store in an array of organisms and exhibit characteristics which are similar to oil-derived plastics, yet have the added advantages of biodegradability and biocompatibility ...

3-Hydroxybutyrate as a Metabolite and a Signal Molecule Regulating Processes of Living Organisms

Biomolecules, 2021
3-hydroxybutyrate (3-HB) as a very important metabolite occurs in animals, bacteria and plants. It is well known that in animals, 3-HB is formed as a product of the normal metabolism of fatty acid oxidation and can therefore be used as an energy source ...

Impact of Multiple Reprocessing on Properties of Polyhydroxybutyrate and Polypropylene

Polymers, 2023
Biobased plastics have the potential to be sustainable, but to explore their circularity further, current end-of-life options need to be broadened.

PHB/PEG Nanofiber Mat Obtained by Electrospinning and Their Performances

Technologies, 2023
In this work, a nanofiber mat based on PHB/PEG with various PEG contents was obtained by electrospinning process. The thermal and mechanical properties of the PHB/PEG nanofiber mat were investigated. In addition, PHB/PEG nanofiber mats were characterized

Polyhydroxybutyrate-co-hydroxyvalerate (PHBV) with Phenolic Acids for Active Food Packaging

Polymers, 2023
PHBV films incorporating 3, 6 and 9% ferulic acid (FA) or p-coumaric acid (PCA) were obtained by melt blending and compression moulding. The films’ microstructures and thermal behaviours were analysed as well as their mechanical, optical and barrier ...

Optimization of Inulin Hydrolysis by Penicillium lanosocoeruleum Inulinases and Efficient Conversion Into Polyhydroxyalkanoates

Frontiers in Bioengineering and Biotechnology, 2021
Inulin, a polydisperse fructan found as a common storage polysaccharide in the roots of several plants, represents a renewable non-food biomass resource for the synthesis of bio-based products.

Tailoring the Nucleation and Crystallization Rate of Polyhydroxybutyrate by Copolymerization

Biomacromolecules, 2023
In the polyester family, the biopolymer with the greatest industrial potential could be poly(3-hydroxybutyrate) (PHB), which can be produced nowadays biologically or chemically. The scarce commercial use of PHB derives from its poor mechanical properties,

Physicochemical characterization of biodegradable polymer polyhydroxybutyrate from halophilic bacterium local strain Halomonas elongata [PDF]

Global Journal of Environmental Science and Management
BACKGROUND AND OBJECTIVES: Petroleum-based plastics produce tremendous amounts of plastic waste every year, which contributes to environmental problems. Biological polymers, such as polyhydroxybutyrate, have caught attention as an ecofriendly substitute ...

Production and optimization of bioplastic (Polyhydroxybutyrate) from Bacillus cereus strain SH-02 using response surface methodology

BMC Microbiology, 2022
Background Polyhydroxybutyrate (PHB) is a biopolymer formed by some microbes in response to excess carbon sources or essential nutrient depletion. PHBs are entirely biodegradable into CO 2 and H 2 O under aerobic and anaerobic conditions.

Construction of an Antibiotic-Free Vector and its Application in the Metabolic Engineering of Escherichia Coli for Polyhydroxybutyrate Production

Frontiers in Bioengineering and Biotechnology, 2022
An antibiotic- and inducer-free culture condition was proposed for polyhydroxybutyrate (PHB) production in recombinant Escherichia coli. First, antibiotic-free vectors were constructed by installing the plasmid maintenance system, alp7, hok/sok, and the ...
