Study of the Biodegradation Properties of Amorphous Blends of Poly(Lactic Acid) and Poly(3‐Hydroxybutyrate‐co‐4‐Hydroxybutyrate) Foamed With Supercritical CO2

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Supercritical CO2 foaming of fully amorphous PLA/PHA blends produced low‐density closed‐cell foams with fine cellular morphology. Blending with PHA enhanced biodegradation under simulated home‐composting conditions, achieving up to 84% mass loss after 4 months, whereas marine degradation remained limited and was mainly restricted to the PHA component ...

(S)-2-Hydroxyisovalerate Production from d-Xylose with CO-Converting Clostridium ragsdalei

Fermentation
Clostridium ragsdalei was found to produce (S)-2-hydroxyisovalerate (2-HIV) as a novel product in addition to acetate, ethanol, and d-2,3-butanediol in heterotrophic (d-xylose), autotrophic (CO), and mixotrophic (d-xylose + CO) conditions.

De Novo Assembly of the Polyhydroxybutyrate (PHB) Producer Azohydromonas lata Strain H1 Genome and Genomic Analysis of PHB Production Machinery

Microorganisms
Polyhydroxybutyrate (PHB) is a biodegradable natural polymer produced by different prokaryotes as a valuable carbon and energy storage compound. Its biosynthesis pathway requires the sole expression of the phaCAB operon, although auxiliary genes play a ...

Effect of Radical Initiators on the Rheological Properties and Toughness of Poly(Lactic Acid)/Poly(3‐Hydroxybutyrate‐Co‐4‐Hydroxybutyrate) Blends

Polymer Engineering &Science, Volume 66, Issue 8, Page 5974-5987, August 2026.
Effect of mixing protocol on the size distribution of PHA domains in the PLA matrix. ABSTRACT In this study, poly(lactic acid) (PLA) and poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3HB‐4HB), a type of polyhydroxyalkanoate (PHA)], were melt‐blended at an 80/20 (wt/wt) ratio, and radical initiators were employed as reactive compatibilizers to enhance

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

Polymer Engineering &Science, Volume 66, Issue 8, Page 6137-6149, August 2026.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

Controle da biossíntese de poli-hidroxialcanoatos bacterianos através do fluxo de substratos Control of the biosynthesis of bacterial polyhydroxyalkanoates through the flux of substrates

Química Nova, 2007
Manipulation of the flux of substrates was utilized to control the amount of 3-hydroxyvalerate and 3-hydroxy-4-pentenoate produced by Burkohlderia sp. The 3HV production rate was directly proportional to the propionic acid uptake rate with the last one ...
