Cascading Beta-oxidation Intermediates for the Polyhydroxyalkanoate Copolymer Biosynthesis by Metabolic Flux using Co-substrates and Inhibitors

Designed Monomers and Polymers, 2023
Polyhydroxyalkanoates (PHAs) are biopolymers that are produced within the microbial cells in the presence of excess carbon and nutrient limitation. Different strategies have been studied to increase the quality and quantity of this biopolymer which in ...

Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

SELEÇÃO POLIFÁSICA DE MICRORGANISMOS PRODUTORES DE POLIHIDROXIALCANOATOS

Química Nova
Polyhydroxyalkanoates (PHAs) are fully biodegradable biopolyesters produced by many prokaryotes and accumulated as insoluble cytoplasmatic inclusions. The detection of these intracellular granule is usually provided using lipofilic azodyes, which are not

Resource acquisition and allocation traits in symbiotic rhizobia with implications for life-history outside of legume hosts [PDF]

Royal Society Open Science, 2018
Resources that microbial symbionts obtain from hosts may enhance fitness during free-living stages when resources are comparatively scarce. For rhizobia in legume root nodules, diverting resources from nitrogen fixation to polyhydroxybutyrate (PHB) has ...

Gamma Irradiation‐Based Free Radical Grafting of N‐Hydroxyethyl Acrylamide onto Poly[(R)‐3‐hydroxybutyrate]

Macromolecular Rapid Communications, EarlyView.
This work demonstrates successful gamma‐radiation‐induced grafting of N‐hydroxyethyl acrylamide onto poly[(R)‐3‐hydroxybutyrate], producing substantial changes in material properties. Grafting generated a biphasic, less crystalline structure with enhanced thermal stability, elongation (65%), toughness (378% increase), and exceptional water uptake (610 ...

Polyhydroxyalkanoate: a biodegradable polymer (a mini review) [PDF]

, 2019
The current synthetic plastic menace has driven researchers to sort sustainable alternatives. Polyhydroxyalkanoate (PHA) has been proven to be sustainable, biodegradable, biocompatible and hence could serve as suitable alternative.
