Co-culturing different colours of bacteria for the microbial art project 🙂🦠🧫

My artistic skills need to develop a bit, but I nearly have all the colours needed for an agar art project ! 🦠🧫

Red bacteria vs white bacteria 🙂

The air sampler collects through a grid with these nice concentric circles

R2A with charcoal and trace element solution

Air sampling gives a nice reminder about about how many fungi we are breathing... 🦠🧫

The start of a new agar art project..... 🧫🦠

SundayScience is kitchen top beer brewing and water analysis 🙂 🦠 🧫

📣 JOB ALERT
We have a fully funded postdoc position open in our group, to work on the topic of Legionella, temperature, buildings and climate change...!

It's not everyday that you find purple colonies... Non-chlorinated tap water on R2A agar 🦠🧫

Sure. Some students volunteered their own shower hoses; we then cut them in subsections, extracted the biofilms through scraping, quantified the biomass with crystal violet staining and observed biofilm heterogeneity along the length of the entire hose.

Teaching the next generations of young scientists a practical course about biofilms in building plumbing potable water... these are some fabulous images from their own shower hoses 🦠🧫

SaturdayScience: Making the microbes work on the weekend.... Garlic Brioche for dinner 🙂

Happy new year everyone!
Day one back in the lab (new year's resolution), testing potable water biofilm staining with crystal violet 🧫🦠

SciArt for the day. Winter series. Blue drinking water biofilm.

Cooking dinner with a work-appropriate splatter board for inspiration 🙂

Academia rule 1
If you submitted a paper before x-mas holidays you have to review a paper during said holidays......

These three are pretty decent, although not so many bacteria images as I would like to have!

decided to ditch biorender, so now I have to draw the biofilms myself . Autumn series, 5 species. 🦠🧫

🦠 🧫 Our hunt for the natural enemies of Legionella is now out on preprint !

Last but not least, I want to thank @drinkmic.bsky.social
and @alecava.bsky.social for all the discussions and support through this journey into the Legionellaceae family!

Tomorrow is open door day at Eawag and we are doing a community science project, looking at the #biofilm in peoples shower hose, and using that as a platform to discuss #legionella and #drinkingwaterquality. Photo shows diverse biofilms from 12 shower hose 😀

I cannot be the only microbiologist who thinks cleaning a drain is just awesome.... 😂 🦠 🧫

We catalogued all 77 known #Legionella species 🙂
Read about it on our LeCo-project blog here:

The complete list is available on Github (github.com/mgabriell1/L...), where we will keep it updated and hopefully expand in the future!

SaturdayScience: fermented flour experiment, char grilled and stuffed with fresh things 🙂

First bread of the new season! The sourdough is wild cherry blossom grown on whole-grain flour.
