Interactive effects of microplastics and arbuscular mycorrhizal fungi on grassland communities

PLANTS, PEOPLE, PLANET, EarlyView.
Grassland plant communities contribute significantly to global biodiversity but face numerous man‐made pressures which may interfere with their ecological functions. One such pressure receiving increasing scientific, political, and public attention is microplastic pollution.

Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, EarlyView.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

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

Biotechnology 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

ChemistryEurope, 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

Novel polyhydroxyalkanoate copolymers produced in Pseudomonas putida by metagenomic polyhydroxyalkanoate synthases [PDF]

Applied Microbiology and Biotechnology, 2016
Bacterially produced biodegradable polyhydroxyalkanoates (PHAs) with versatile properties can be achieved using different PHA synthases (PhaCs). This work aims to expand the diversity of known PhaCs via functional metagenomics and demonstrates the use of these novel enzymes in PHA production.
