Dyeing of textile materials by bacteria

Scientists are working to use microbes as dye factories and as a tool for printing patterns on fabrics instead of synthetic dyes. In a project at the University of Rotterdam, scientists have given pigmented bacteria the ability to produce sound pigments, and found that pigment production increased, indicating that it could lead to increased pigmentation. Of the bacterial dyeing process.

Research by designers Laura Luchtman and Ilfa Siebenhaar. With the help of sound engineer Eduard van Dommelen, the designers built a cluster of acoustic equipment in the biomedical laboratory. By making the bacteria dance, they tried to eliminate random growth to create beautifully textured fabrics.

Research is part of two designers' Living Color Living Design project. Biological design is the intersection of nature, science and design in which living organisms form an integral part of the design process.
It has been found that the sound frequencies helped accelerate pigment production. While bacteria are not affected by the sounds that make up the stains on the fabric, the bacteria that are dancing make the fabric dyed in plain color. Although the results are contrary to what the group is aiming for, the results may lead to ways to increase the size of the bacterial dye process.
Bacteria that are growing as a dyeing plant can lead to more sustainable staining because these bio pigments are a substitute for toxic synthetic textile dyes.
The study was inspired by the phenomenon of creating patterns from acoustic vibrations such as Chladni motifs and Faraday waves, which render the material geometrically shaped when exposed to sound.
