In vivo immobilization of an organophosphorus hydrolyzing enzyme on bacterial polyhydroxyalkanoate nano-granules

open access: yesMicrobial Cell Factories, 2019
Background Polyhydroxyalkanoate (PHA) are nano-granules naturally produced by bacteria. Two types of proteins, PHA synthase (PhaC) and phasins (PhaPs), are attached to the PHA surface by covalent and hydrophobic interactions.

Effects of Cardamom on Neuroinflammation, Learning and Memory in Mice Fed a Cafeteria Diet

open access: yesEndocrinology, Diabetes &Metabolism, Volume 9, Issue 2, March 2026.
Cardamom supplementation (500 mg/kg/day) improved memory, reduced anxiety and neuroinflammation in mice fed with a cafeteria diet. Behavioural tests showed enhanced cognitive functions, while TNF‐α and lipid markers decreased significantly. These findings suggest cardamom's potential as a neuroprotective agent against diet‐induced memory and metabolic ...

Mutants deficient on polyhydroxyalkanoate (PHA) accumulation and construction of recombinants to control monomer composition on PHA

open access: yes, 2010
Pseudomonas putida produz PHA de cadeia média (PHAMCL) a partir de carboidratos e óleos vegetais. Genes de biossíntese de P3HB (poli-3-hidroxibutirato) de Ralstonia eutropha foram inseridos em P. putida IPT046 selvagem e mutantes PHA-.

Production of functionalized polyhydroxyalkanoates by genetically modified Methylobacterium extorquens strains

open access: yesMicrobial Cell Factories, 2010
Background Methylotrophic (methanol-utilizing) bacteria offer great potential as cell factories in the production of numerous products from biomass-derived methanol. Bio-methanol is essentially a non-food substrate, an advantage over sugar-utilizing cell

Increased Production and Molecular Weight of Artificial Polyhydroxyalkanoate Poly(2-hydroxybutyrate) Above the Glass Transition Temperature Threshold

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Poly(2-hydroxybutyrate) [P(2HB)] is an artificial polyhydroxyalkanoate (PHA) synthesized using engineered 2-hydroxyalkanoate-polymerizing PHA synthase. In the present study, the effect of temperature on P(2HB) synthesis was investigated.

Functional expression of the PHA synthase gene phaC1 from Pseudomonas aeruginosa in Escherichia coli results in poly(3-hydroxyalkanoate) synthesis

open access: yes, 1997
The potential of the production of polyhydroxyalkanoates (PHA), consisting of medium-chain-length (MCL) hydroxyfatty acids (C5–C14), in recombinant Escherichia coli was investigated. E.

Synthesis and Physical Properties of Polyhydroxyalkanoate Polymers with Different Monomer Compositions by Recombinant Pseudomonas putida LS46 Expressing a Novel PHA SYNTHASE (PhaC116) Enzyme

open access: yesApplied Sciences, 2017
A recombinant of Pseudomonas putida LS461 (deletion of the phaC1phaZphaC2 genes) was constructed by introducing cosmid JC123 carrying a novel phaC116 gene from a metagenomic clone. The resulting strain, P.

Comparative metagenomics of PHA synthase genes in soil

open access: yes, 2017
Polyhydroxyalkanoates (PHAs) are biopolymers produced naturally by bacteria. They are of considerable scientific interest as fundamental components of bacterial carbon metabolism and have biotechnological applications as potential bioplastics.

In vivo enzyme immobilization by use of engineered polyhydroxyalkanoate synthase

open access: yes, 2006
This study demonstrated that engineered polyhydroxyalkanoate (PHA) synthases can be employed as molecular tools to covalently immobilize enzymes at the PHA granule surface. The β-galactosidase was fused to the N terminus of the class II PHA synthase from
