Artist Harnesses Bacteria to Screen-Print Stunning Fabrics

Is there any limit to what bacteria can achieve? Guided by the expertise of researcher and designer Natsai Audrey Chieza, these microscopic organisms have found a surprising place in the fashion world, providing an eco-conscious and visually stunning replacement for traditional dyes.

The fashion industry is grappling with what Chieza describes as "an existential crisis," she shared with Mytour, "due to its status as the world's second-largest polluter." The challenges are twofold: textile manufacturing consumes vast quantities of water and generates significant petrochemical byproducts.

Reflecting on these challenges, Chieza explored whether biology could offer a solution. She experimented with Streptomyces bacteria, encouraging them to produce their vibrant natural pigments on delicate pieces of silk.

She described the process as unlike any other printing method she’s encountered, as the living bacteria are invisible to the naked eye and act as unpredictable artistic partners. Factors like room temperature, pH levels, and the size of their petri dish environment all affect how the microbes deposit their dye.

With a foundation in art and design, Chieza recognized the potential of her discovery and sought out scientific collaborators. After working alongside synthetic biologists as a designer-in-residence at University College London, she connected with Christina Agapakis, the creative director at Ginkgo Bioworks, a platform dedicated to organism design.

"Our specialty lies in understanding microbes, how to work with them, and ensuring their well-being," Agapakis shared with Mytour. "We believe biology offers an incredible way to create materials."

The artist and the organism designers are currently "exploring multiple avenues simultaneously," Chieza explains. A key focus is scaling—figuring out how to expand a microscopic process to dye full garments and large quantities of fabric, transitioning "from the biological level to wearable and even architectural applications."

"At Ginkgo," she adds, "we’re exploring how to produce enough to meet the growing demand for sustainable materials. How can we bridge the gap between 250 milliliters and 50,000 liters?"

A significant challenge lies in developing entirely new technology to support this innovative dyeing method, ensuring it is both eco-friendly and resource-efficient.

Throughout the process, Chieza reflects on questions like, "What is the broader significance? How does this impact society? Will it genuinely address the issue at hand?"

We eagerly await the answers.
