1/3 To those interested in microbial iron & metal transport: In 1992, the late JB Neilands (UCB), the pioneer in the study of Fe transport entrusted me with his collection of purified siderophores from a wide range of microbes—many of them unique chemical species that can no longer be reproduced

Two intensive sampling periods of oyster-associated vibrio and their phage, 4 years apart, and many surprises. Despite being washed by the Atlantic, wide tides, and vibrio (almost?) disappearing most of the year, we can find the exact same virulent phages 4 years later (down to 0 SNP)! preprint👇

Glad to share the work of @yli18smc.bsky.social and co on Lamassu, a bacterial defense system related to Rad50/Mre11 (RM). While RM carefully trims DNA ends for repair, Lamassu chops up the host chromosome. Our study reveals how it is regulated to minimize damage, activating only during infection.

Do they? I only know that Wolffia australiana mostly tastes neutral.

Omw, to the last conference this year. Quick stop in Aachen and then onwards to Wageningen. Really looking forward to this first conference after defending my thesis. 🚝

Excited to share our preprint led by Carlos Voogdt et al

We developed new genetic tools & genome-wide libraries for species of the Bacteroidales order; constructed saturated barcoded transposon libraries in key representatives of three genera.

Thanks a lot, Nico!
Looking forward to seeing you next week! ☀️🌻🌈🦠

Thanks a lot Henryk , I feel very relieved. 🌈😂

Me standing next to my 'Thank You' slide, after my talk. I look super exhausted , while on the slide there is a big photo of me being energetic and smiley.

Thank you!

I think this photo of the event is one of my favorites.

Thank you! Today, two days later, I really feel relieved. I slept well and am feeling relaxed. 🌻☀️

Thanks a lot, mate! It's very appreciated. 🫂🌈💐❤️

Thank you to everyone who wished me luck!! 🥹🫂❤️🌈

Everything worked out well!!

@lsi.bsky.social as we say in Germany: Legally I am for the moment not required to deny the title Dr. rer. nat. if someone is calling me so.

#PhDone

I also got these great shots with my PI:

Hahaha , that's true. Yes , it will go well. 🌈

Thanks a lot Helena! 🌻

In 2021 I found my postdoc job via Twitter. Got to connect with a lot of scientists via Twitter and now BlueSky.

Thank you 🙏🏻

I am defending my thesis today.
Barely slept. When I don't concentrate for a moment my thoughts immediately go back to my presentation.

I will be very happy once this is over. 😂

Wish me luck! 🌈

SegMantX: a novel tool for detecting DNA duplications uncovers prevalent duplications in plasmids Abstract. Segmental duplications play an important role in genome evolution via their contribution to copy-number variation, gene-family diversification an

Happy to introduce SegMantX. Analyzing #plasmid we find that most duplications are MGE-driven. Additional use cases include detection of DNA transfer between replicons and examination of plasmid sequence similarity. Try it out! doi.org/10.1093/molb...

Bringing the uncultivated microbial majority of freshwater ecosystems into culture - Nature Communications A large fraction of aquatic bacteria remains uncultured. Here, the authors cultivated 627 strains of abundant freshwater bacteria from 14 European lakes, thus generating a collection that includes many previously uncultured, oligotrophic bacteria that may serve as model organisms.

⚠️New paper ➡️ isolating >600 freshwater microbes using dilution-to-extinction and low-nutrient, lake-mimicking media.

🤯Expands cultured diversity to ~70 % of detected genera and enables physiological studies of streamlined oligotrophs.
