Happy to see our newest publication out in Water Research https://doi.org/10.1016/j.watres.2026.126123
We establish bacteria from the genus Novosphingobium as model organisms to study bacterial mechanisms for removing #micropollutants in activated carbon filters.

I've got a quick question for the friendly microbiologists of Mastodon.
It's my understanding that it's common for some environmental change to wipe out 90+% of a bacterial colony, only to have the survivors quickly multiply back to their original numbers, this time with a mutation that grants resistance to whatever the threat was.
Is there a name for this phenomenon (not "gene fixation," but the die back and recovery)? Are there canonical papers about it?
EDIT: I think "population bottleneck" is the best way to describe what I mean, though I got a few other very good suggestions for related terms.
Thanks everyone! You guys are the best. ❤️
For #MountainMonday this week I have a photograph of clouds clearing on the side of Mount Cheam (Lhílheqey) in Chilliwack, British Columbia, Canada.

Gut Respiration
Noteworthy — A surprisingly high number of respiratory reductases were found in some gut bacteria.

Heute ist Sperrmüll-Abfuhr im Kreuzviertel und einige Fahrräder wurden bereits mit einem Band gekennzeichnet.
Was ist Schrott und was ist nicht?
Im Bild seht ihr den geplanten Vorgang, Bild von der Stadt MS:
„kleinere Schäden reichen nicht aus“ Aha 👀
Klar ist, es steht viel Schrott herum. Auch Autos.

Last year, I made 26 batches of homemade yogurt and ate probably over 350 yogurt and granola breakfasts (or some variation of that). Since I left the world of laboratory bench work, the kitchen has…
👋 We had a successful and fun conference at #vaam2026 together with our partners and collaborators @deNBI and @dsmz !
🙏 Thank you to all our booth visitors for the interesting questions and thought-provoking discussions. Talk to you soon about more free-of-charge tools, services and best practices for microbiology data and analysis.
👉 See you at other events soon: https://nfdi4microbiota.de/newsroom/events/
📢 Are you at #vaam2026 ?
👉 Stop by the NFDI4Microbiota booth to learn how we can support you with training, data analysis, and making your microbiome research easier to share, reuse, and scale.
And don’t miss today’s panel discussion at 1:30 in Lecture Hall B!
We’d love to meet you 👋!
