Very sad news about the passing of Prof. Jeff Cole. Jeff was a central figure for biotechnology in Europe who inspired generations of researchers. R.I.P.🕊️

There was an interest a few years ago to establish a PseudoWiki, which unfortunately did not materialize. Other than the Tn5-insertion collection mentioned by @jjimenez.bsky.social, I don't know of any repository—but get in touch if we can help with our own collection!

How do you react when your favorite microbe is renamed by taxonomists who are completely outside your field—and who ignore the community that actually works with it? Here is our clear answer re the case of Pseudomonas putida KT2440 👉🏻 journals.asm.org/doi/10.1128/...

Microbes are life, the biological core of One Health and Health in All Policies The World Health Organization (WHO) is promoting the operative concept of “Health in All Policies” (HiAP; https://iris.who.int/bitstream/handle/10665/11263

Microbes determine the health of all other organisms and that of the planet. They were our ancestors and are our cousins. They are life and sustain it.

Synthetic C1 metabolism in Pseudomonas putida enables strict formatotrophy and methylotrophy via the reductive glycine pathway | mBio Soluble C1 feedstocks, such as formate and methanol, have gained attention as sustainable substrates for biotechnology, with the potential to reduce greenhouse gas emissions and reliance on sugar-based resources.

🚨 New paper in mBio!
We established strict formatotrophic & methylotrophic growth in engineered Pseudomonas putida via the reductive glycine pathway (rGlyP). journals.asm.org/doi/full/10....
Here’s a teaser of how we did it 🧵👇1/5

3/4 Our perspective lays out:
1️⃣ A blueprint for designing next-gen synthetic C1 microbes
2️⃣ A roadmap for engineering P. putida into an autotrophic chassis
3️⃣ A circular carbon economy vision, revalorizing CO₂ + waste streams
📊 Together, these steps connect design → engineering → sustainability.

A blueprint for designing the next-generation of synthetic C1 microbes - Nature Communications Synthetic one-carbon assimilation could contribute to a more sustainable and circular carbon economy, but much work in this field has focused on model microorganisms. Here the authors provide their perspective on the potential value of non-model microbes, and how that potential could be realised.

🚀 Thrilled to share our new Nature Communications article:
“A blueprint for designing the next-generation of synthetic C1 microbes”
We propose a framework to unlock sustainable, carbon-efficient biomanufacturing using non-canonical hosts.

We are deeply saddened by the news that Andrew D. Hanson (@adhansonlab.bsky.social) is no longer with us. He was an exceptional scientist, mentor, and leader in multiple fields. He constantly reminded us that over-promising would backfire. Rest in peace, Andrew.

Andrew was a force of nature. He remained active until the very end and wrote a couple of very moving, lucid, and sharp farewell emails that I will always treasure. R.I.P. Andrew 🕊️
