Bone generation on PHBV matrices: an in vitro study

Biomaterials, 2003
Bone formation was investigated in vitro by culturing rat marrow stromal osteoblasts in biodegradable, macroporous poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) matrices over a period of 60 days. Foams were prepared after solvent evaporation and solute leaching.

A Novel Link Between Electron Transport Chain Modulation and mcl-PHA Production in Pseudomonas aeruginosa 5300 Using Azide as a Modulator. [PDF]

Environ Microbiol Rep
The oleic acid and azide inhibited the cytochrome c oxidase activity in Pseudomonas aeruginosa MCC 5300, shifting the electron flux towards bd‐oxidase. This resulted in more NADH consumption to maintain the proton gradient for energy generation. The rapid depletion of NADH triggered high mcl‐PHA accumulation.

Microbiological Characterization of the Biofilms Colonizing Bioplastics in Natural Marine Conditions: A Comparison between PHBV and PLA

Microorganisms, 2023
Biodegradable polymers offer a potential solution to marine pollution caused by plastic waste. The marine biofilms that formed on the surfaces of poly(lactide acid) (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were studied.

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 ...
