🤝🌍 Last week, the #TOLERATE EU project consortium meeting took place in Groningen, The Netherlands. Partners came together for two intensive and productive days to share updates, reflect on progress, and align on next steps across all work packages.

For all PhD candidates interested in #syntheticbiology consider our #EMBOSynBio course! Applications open!

How does Pseudomonas putida keep its redox balance steady across different metabolic states? Our new preprint shows that two transhydrogenases -membrane-bound PntAB and soluble SthA - act together as a flexible, reversible system to control NAD(H)/NADP(H) ratios. www.biorxiv.org/content/10.1...

New phi15-based expression system in Pseudomonas putida uses #SEVA plasmids for high-yield gene expression. The work by @pabnik.bsky.social shows how single-copy vectors minimise toxicity, achieve 200×induction, and outperform T7 systems. 👉 www.nature.com/articles/s42...

Today, the #TOLERATEProject held its 1st Review Meeting (M1–M18) with PO & PM highlighting our progress, innovation & first results. A key step to shape the road ahead! 🔬🌱💦 Learn more: https://tolerate-eu-project.com/  #HorizonEurope #EUProjects #Biotechnology #SustainableAgriculture

Ethylene glycol is widely used as monomer of the plastic PET. It is therefore highly relevant as sustainable feedstock for microbial biotechnology. In our new paper in @natcomms.nature.com, we characterize efficient enzymes for ethylene glycol oxidation: www.nature.com/articles/s41...

Back from an inspiring week at #ME16 in our home #Copenhagen! 🌍 Engaging talks, exciting science, and amazing connections — we’re full of new ideas! 🎉 Big congrats to @giusifav.bsky.social for winning a poster award 🏆 🙌 And proud to have our PI @pabnik.bsky.social as co-chair of the event!

Happy to host @kunjapur.bsky.social as a sabbatical #professor at DTU Biosustain, supported by Otto Mønsteds Fond!

Pseudomonas putida joins the Olympus of effective Cell Factories www.nature.com/articles/s41... Not any longer *a promising platform* for metabolic engineering, but a phenomenal, consolidated chassis for programming degradation and synthesis of amazing molecules 😃!

Congrats to Garret for officially becoming Dr. O'Connell! Garret had his Ph.D. viva on synthetic #fluorochemical #metabolism in #Pseudomonas today. Thanks to @tilmweber.bsky.social r.bsky.social, @pavelcito.bsky.social & Esteban Martinez for their insights🧪🦠 #SynBio @labnikel.bsky.social

Microbes like Cupriavidus necator naturally grow on #renewable feedstocks ♻️🧫 (CO₂, formate, hydrogen), yet their potential remains untapped due to the lack of efficient genetic tools... 1/2 www.cell.com/trends/biote...

Glad to see Julia Vorholt as winner of the @novonesis.com #Biotechnology Prize 2025 for her research on the plant #microbiome — among other achievements (e.g. synthetic C1 assimilation). Amazing and inspiring colleague #WomenInScience @eth-dbiol.bsky.social novonordiskfonden.dk/en/news/pion...

Very happy and proud of this work led by @beaubd.bsky.social with many others involved, in which we show that synthetic C1 metabolism can do better than nature for biotech!

The utilization of #C1-feedstocks, such as methanol, by non-model bacteria demands an in-depth analysis of design alternatives, a modular strategy to identify bottlenecks and efficient solutions within the host #metabolism of the chosen host... www.biorxiv.org/content/10.1...

With great collaborations come great outcomes! A fine example from @eorsi.bsky.social from @pabnik.bsky.social's lab et collaborators of how to design, build and develop cell biosensors for value-added chemicals (related to synthetic C1 assimilation, of course)! 🧪
