Controlled Feeding Facilitates the Development of a Robust Production Process for Terpolymeric Polyhydroxyalkanoates

open access: yesBiotechnology Journal, Volume 21, Issue 6, June 2026.
Graphical Abstract and Lay Summary Cupriavidus necator NCIMB 11599 was cultivated with a fully automated pH–pO2‑dependent feeding strategy that enables controlled levulinic acid delivery and robust production of PHBVV terpolymer. The process was successfully transferred from 7.5 to 42‑L stirred‑tank reactors, maintaining PHA contents of ∼75% CDW and ...

Hydrogenative Conversion of C5 Biomass Feedstock Furoic Acid to δ‐Valerolactone on Pt‐Loaded Silicoaluminophosphate

open access: yesChemistryEurope, Volume 4, Issue 6, June 2026.
Novel Pt catalysts supported on zeolitic silicoaluminophosphate efficiently promoted the hydrogenative conversion of furoic acid to δ‐valerolactone under mild conditions. High activity arose from finely dispersed Pt nanoparticles stabilized by the porous support. Mechanistic studies indicated site‐selective partial hydrogenation followed by Csp²–O bond

Nanoscale Ordering of Magnetosomes Under the Influence of a Magnetic Field Investigated by Small‐Angle X‐Ray Scattering

open access: yesSmall Structures, Volume 7, Issue 6, June 2026.
Recently, the synthetic Rhodospirillum rubrum ‘magneticum’ has been shown to enable the light‐driven production of magnetosomes (MAGs) in high yields. These membrane‐enveloped magnetic nanoparticles represent promising alternatives to their chemically synthesized analogs for many applications in the biotechnological and biomedical field.
