@spp2389
From single cells to intricately constructed colonies - bacteria are multicellular wonders! An interdisciplinary research effort to unravel the intricate paths, regulation systems and structures behind the multifaceted forms of bacterial multicellularity
Interested in the regulation and evolution of multicellularity in Strepromyces?
Natalia Tschowri (@unihannover.bsky.social) and Daniel Rozen (@unileiden.bsky.social) are looking for a PhD student as part of #SPP2389 !
#PhDposition
And we’re back! The second funding period of #SPP2389 started this week with our kickoff meeting in Grimma
Stay tuned in the next few weeks/months to get to know both the old and new members working on projects centered around the fascinating world of bacterial multicellularity! 🦠
Our latest paper on Guanidine metabolism in #Cyanobacteria is out @pnas.org
(it's useful as N nutrient but toxic at the same time)
A great collaboration w Klähn lab w small part from us on toxicity😅

Last chance to visit Bakteriopolis at the @tudresden.bsky.social Excellence Days event!
Surface matters! Chitin alters both intraspecies interactions and biofilm architecture in Vibrio cholerae in marine snow
Preprint on @biorxiv-microbiol.bsky.social ⬇️
Cellulose is a critical component in the cell wall of Streptomyces, and accessory proteins involved in its biosynthesis support both its unique cell envelope and multicellular filamentous growth

Bakteriopolis is in Halle at the #SilbersalzFestival this week! Even Come try water kefir, make your own bacterium, and learn about the hidden world of multicellular microbes! #SPP2389 #microsky #wisskomm
Danke an Mainzelmännchen Det für den Besuch! @zdfde.bsky.social
@kostchristian.bsky.social has an open PhD position as a part of #SPP2389 !

I’ll second MYM! Seems to be a good allrounder for most of the natural isolates we’ve worked with
Interested in working on microbial interactions and cooperative cross-feeding? Join @kostchristian.bsky.social as a part of #SPP2389 !
From polymicrobial water kefir grains to PCD in biofilms, microorganisms are magnificently multicellular!
Thanks to @embo.org @ibe-barcelona.bsky.social for having Lena Friebel and Thorsten Mascher @tudresden.bsky.social as well as @escolizzi.bsky.social at the
#Multicellverse workshop
You can’t talk about microbial multicellularity without mentioning Streptomyces - check out our collaborator Daniel Rozen’s experimental evolution of these filamentous bacteria!
Thanks @martaalvarez.bsky.social for snapping a pic!
@embo.org #Multicellverse
Our head of #SPP2389 Thorsten Mascher also put the spotlight on the multicellular microbial communities of water kefir - thanks again @evolvedbiofilm.bsky.social !
@embo.org #Multicellverse
Lena brought her research on cannibalism in Bacillus biofilms to the @embo.org multicellularity workshop! Thanks @evolvedbiofilm.bsky.social for the picture! #Multicellverse
All cells – from mammalian cells to microbes – can follow different biological paths. Whether they grow and divide, specialise, age or die depends on the pathway they take. New findings by researchers at ETH Zurich could help influence a cell’s decisions to target diseases such as cancer.
A bit late 🙃 but happy to share our recent findings on #cdiAMP signaling in controlling #cyanobacteria #diurnal rhythm in @cp-iscience.bsky.social

#cdiAMP is involved in almost all cellular processes, explaining it's essentiality in #cyano

PhD position on Regulation and Evolution of Bacterial Multicellularity ( #Streptomyces ) within @spp2389.bsky.social supervised by Natalia Tschowri (Hannover 🇩🇪) and Danny Rozen (Leiden 🇳🇱) with research at both locations
deadline: October 31, 2025

Streptomyces and other filamentous actinomycetes are treasure troves of a vast collection of antibiotic compounds - an evolutionary feature linked to their unique multicellular lifestyle
Curious about kin recognition systems? Take notes from Proteus and Myxococcus!

Congratulations to our Matthias for winning the @femsmicro.org international microorganism day microbe art contest for best photo and best overall! 🎉🦠
Biofilms truly are beautiful works of multicellular microbial architecture 🏛️

We loved hearing @khammerschmidt.bsky.social talk about evolution at the #MultiBac2025 conference this January - check out the @asm.org report on the origins of early microbial life!
A very interesting study by @cyanofur.bsky.social Lab on biofilm formation by filamentous #Cyanobacteria Nostoc
Could be interesting for @spp2389.bsky.social

Congrats to @mcaroec.bsky.social on winning a talk prize at #BACELL2025 !
Our #SPP2389 associated PhD student Luis gave a great talk on the effects of experimental evolution on Streptomyces aggregates and colonies at the #ISBA2025 !
Another #SPP2389 PhD student Martha with a great talk on phase transitions in B. subtilis macrocolonies!
Thanks again to @evolvedbiofilm.bsky.social for capturing the moment! #BACELL2025
One of our SPP PhD students Lena presented her research on cannibalism in B. subtilis biofilms at the #BACELL2025 today!
Thanks to @evolvedbiofilm.bsky.social for snapping a pic!
Only 2 more days until the ISBA! Genna's looking forward to 5 days of nothing but actinomycetes and the beautiful North Sea.
Tot snel!
