Nanofillers to Improve the Barrier Properties of Biobased Substrates of Flexible Printed Electronics

Advanced Energy and Sustainability Research, Volume 7, Issue 8, August 2026.
Replacing the fossil‐based substrates of supercapacitors containing liquid electrolytes with biopolymers requires an improvement in their barrier properties. Here, the abilities of three different nanofillers to lower the permeabilities of biopolymers are investigated. 20 w‐% of nanoclay Nanomer I.28E mixed into polyhydroxybutyrate has the best barrier

Improved polyhydroxybutyrate (PHB) production in transgenic tobacco by enhancing translation efficiency of bacterial PHB biosynthetic genes [PDF]

Journal of Bioscience and Bioengineering, 2011
Polyhydroxybutyrate [P(3HB)] was produced in the transgenic tobacco harboring the genes encoding acetoacetyl-CoA reductase (PhaB) and polyhydroxyalkanoate synthase (PhaC) from Ralstonia eutropha (Cupriavidus necator) with optimized codon usage for expression in tobacco. P(3HB) contents in the transformants (0.2mg/g dry cell weight in average) harboring

Pressure Dependent Changes in CO2‐Concentrations Modulate the 3‐Hydroxyvalerate Fraction in Terpolymeric Polyhydroxyalkanoates

Biotechnology Journal, Volume 21, Issue 8, August 2026.
Graphical Abstract and Lay Summary The influence of pressure conditions on the production and composition of terpolymeric PHA were investigated in the technical and the pilot scale. The impact on YX/LA & YPHA/LA and polymer composition (YX/Gluc: 0.31 ± 0.01 gX gGluc−1→0.41 ± 0.01 gX gGluc−1; YPHA/LA: 0.35 ± 0.02 gPHA gLA−1→0.23 ± 0.02 gPHA gLA−1; 3HV ...

Analysis of mutational effects of a polyhydroxybutyrate (PHB) polymerase on bacterial PHB accumulation using an in vivo assay system [PDF]

FEMS Microbiology Letters, 2001
Polymerase is a central enzyme involved in the biosynthesis of polyhydroxybutyrate (PHB), a well-known bacterial biodegradable polyester. In this study, we have established an in vivo assay system to analyze mutational effects of Ralstonia eutropha polymerase (termed PhbC(Re)) on the level of PHB accumulation in recombinant strains of Escherichia coli.

Flame retardancy of sustainable polylactic acid and polyhydroxybutyrate (PLA/PHB) blends

International Journal of Biological Macromolecules, 2023
Nowadays, development of new biobased/biodegradable polymers from biological resources is of great interest from a sustainability standpoint. Polyhydroxybutyrate (PHB) and polylactic acid (PLA) are two biopolymers obtained from renewable resources. In this study, the flame-retardant effect of a newly developed flame retardant (FR) based on melamine in ...

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Mechanistic Insight with HBCH₂CoA as a Probe to Polyhydroxybutyrate (PHB) Synthases

ACS Chemical Biology, 2014
Polyhydroxybutyrate (PHB) synthases catalyze the polymerization of 3-(R)-hydroxybutyrate coenzyme A (HBCoA) to produce polyoxoesters of 1-2 MDa. A substrate analogue HBCH2CoA, in which the S in HBCoA is replaced with a CH2 group, was synthesized in 13 steps using a chemoenzymatic approach in a 7.5% overall yield.
