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!

International Microorganism Day - Microbe Art Contest Winners

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 🏛️

A bit late to the party, but happy belated international microorganism day!

The what, when, where, and why of wrinkly morphology in biofilms Wrinkling is a striking emergent behavior that occurs in microbial biofilms across many species. The phenomenon originates from an intricate interplay between e

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!

Bacterial colony biopsies: Spatial discrimination of heterogeneous cell types by cytometric fingerprinting Colonies of pure bacterial strains are highly dense cellular structures organised in distinct and typical arrangements. The size, shape and variability of bacterial colonies are strongly species-d...

Bacterial colony architecture is heavily influenced by the strain and its environment - how can we study the spatial organization of these heterogeneous groups?
Susann Müller's group developed a method for biopsies on the microscale!

Throwback Thursday to our international conference in January!
120 PhD students, PIs, and guest speakers met in Berlin to present their amazing research on multicellular bacteria (and some archaea!)
Congratulations to our poster prize winners Ruth Viveros, Miriam Epping, and Danielle Lange!

Hi everyone and welcome to our profile for the DFG-funded SPP 2389 on emergent functions of bacterial multicellularity!

A lot has happened recently and we're looking forward to sharing all things bacteria, biofilms, and beyond with all of you!
