E. chromi: Designer Bacteria for Color-Coded Disease Detection
By Maria Popova
Last year, I had the pleasure of profiling the extraordinary artist Daisy Ginsberg for Wired UK. (We also shared a crazy New York adventure that involved a Russian homeless man with Cheetos in his beard and anterograde amnesia.) I called Ginsberg a “postmodern Michelangelo” — and she very much is one, working at the fascinating intersection of design and research as she explores the bleeding edge of art and science, particularly the field of synthetic biology.

E.chromi is one of Ginsburg’s most notable projects — an ambitious collaboration in which she and designer James King partnered with seven Cambridge University biology undergraduates to develop a designer strain of bacteria capable of detecting and notifying you of the concentration of pollutants in water by secreting colors visible to the naked eye. The team designed standardized sequences of DNA called BioBricks, each containing genes from existing organisms capable of producing color, and inserted them into E. coli bacteria.
The project won MIT’s International Genetically Engineered Machine Competition in 2009 and the film about it recently won the best documentary award at Bio:Fiction, the world’s first synthetic biology film festival.
Synthetic biology is promising to change the world, from sustainable fuel to tumor-killing bacteria. But personally I’m skeptical about how we should use it — just because we can do it doesn’t mean we should.” ~ Daisy Ginsberg
What makes E.chromi most fascinating are its diverse and tremendously valuable real-life applications, from testing groundwater for arsenic to producing natural, chemical-free colorings and dyes for food and textiles to personalized disease monitoring via custom probiotic yogurt.
