Bacteria are often considered ugly and stinky; something dangerous that wants to get on us, and that we need to protect ourselves from. Fermentation is one way to overcome that prejudice and find pleasure and beauty in what many people fear, misunderstand, or even loathe. Another way is art, which can utilize microorganisms as metaphors and aesthetic experiences. But, do things need to be pretty so they can talk to us?

In this episode of Ferment Radio, we go on a journey through the artistic work of Anna Dumitriu. Her interdisciplinary practice merges art, science, and technology to explore issues around health, disease, and the societal impact of scientific progress. Anna collaborates closely with scientists and historians, incorporating biological materials like bacteria and DNA into her installations, sculptures, and performances. Through her work, she invites viewers to reconsider common perceptions of the natural world.

We choose our tools, and in return, our tools shape us. Tools can be an opening to new possibilities, but also a limitation. What makes the workspace of a fermenter? What tools are there available? How do these tools influence the process?

In this episode, we sneak peek into the kitchen of David Zilber, chef, fermenter, food scientist, and author of The Noma Guide to Fermentation. Guided by David’s voice, and powered by imagination, we stroll around his lab at Chr. Hansen in Hørsholm, Denmark.

This is the second part of our interview with David Zilber. Check out episode 36 to learn more about the importance of  “little” ferments in the “big” food system.

It looks like a square, monochromatic, glass slide photo, and not only because of the material it is made of, but also because it could belong to a different time. It feels as if the face that emerges from there and gazes at you must have posed for a very long time for the exposure to do its job. Only if you could stare at it uninterruptedly for days, or years, would you be able to notice that the image is in constant change. It is alive. It comes from nowhere, and disappears into what comes next. It is called yeastogram.

Yeastograms are living images made of yeast cultures growing on agar plates and carved with UV light. One of the people who have mastered this technique is Johanna Rotko, a visual artist based in Lahti, Finland. Yeastograms are a lot about fine-tuning the technology. But it goes beyond that. It is also about bringing the imagery of deceased people back to life, waiting for the uncontrollable to do its job, killing and letting live. In other words, it is about time. It is about patience.
