And here it is: the final protocols for your future favorite 16S rRNA gene primer pair for anplicon sequencing studies -> V4EXT. P.S. Mighty are the small ones - metric💩tons of Patescibacteria everywhere. Except in 💩, that is. academic.oup.com/ismecommun/a...

I did not do justice to the great work of @bcoltman.bsky.social on MetaCoOc in this thread. A manuscript describing the tool fully, and a stable release of the code, are in preparation. In the meantime, the code can be found here: github.com/bcoltman/met...

In addition, the environmental metadata is included in the amino acid sequence toolkit (AASTK) SQL database, and can be directly accessed using the Meta command. Thus, any dataset of GlobDB derived AA sequences can be annotated with their primary environments. More on this here: globdb.org/aastk

We now provide environmental metadata for the GlobDB genomes! 🖥️🧬🦠 More info here: globdb.org/news 🧵

Our new preprint introduces #kineochelins, a new group of #siderophores produced by the Antarctic soil actinomycete 🦠🔬🧫 #Actinokineospora sp. UV203 Kudos to the amazing Stanislava Králová & a fantastic team of collaborators 🤩 #microbiomesky www.biorxiv.org/content/10.6...

Phage–host interactions are a key driver of microbial ecology, but observing them in nature is hard! With metaHi-C, we detect freshwater phage–host pairs and link their infection dynamics to evolution. Together with @nadal-molero.bsky.social & Ana Martin-Cuadrado www.biorxiv.org/content/10.6...

A diet enriched in microbiome-fermentable substrates (more fruits and veggies) was shown to be associated with lower frailty and lower mortality risk in an older cohort (N>6000; 65+ y/o), with inflammation markers significantly mediating the dietary effect. link.springer.com/article/10.1...

Respiratory endosymbionts, that allow their ciliate hosts to breathe nitrate instead of (or in addition to) oxygen are frequent members of the wastewater microbiome. 🦠 🖥️🧬 Great to see this work by @louison-nicolas.bsky.social published in ISME coummuncations! doi.org/10.1093/isme...

Microflora Danica: What can you learn from collecting and sequencing 10,000+ samples from a single country? Check out our new paper in @nature.com to find out. Incredible work led by Caitlin Singleton, Thomas B. N. Jensen, and Mads Albertsen from @aau.dk. 🦠🧫🧬 www.nature.com/articles/s41...

This nice summary by @michiwagner4.bsky.social makes it easy to fit my post in a few characters. Amplicon sequencing is still an affordable and quick way to get good insights into who lives in your samples. Our new primers make sure your vision is 20/20. Try em, and contact me if you have questions!

Congrats to Nils Ganzwohl and Carolin Otersen for winning the Poster prizes at the 28th European Nitrogen Cycle meeting #ENC28

Our new preprint on mixotrophy of sponge-associated AOA via the uptake of branched-chain amino acids is online. www.biorxiv.org/content/10.1...

Jan Erisman closed the 28th European Nitrogen Cycle Meeting with a raw reminder: the nitrogen cycle is out of sync! Still, the meeting was full of inspiring research on all things N and some promising paths to reduce our impact! Big questions remain… #ENC28 univie.eventsair.com/enc2025/
