Textile dyes are one of the leading causes of The dyeing process uses lots of water, and much of this water ends up in nearby . And dye wastewater, such as the effluent from production, contains dangerous Toxic chemicals are also sometimes left behind in your clothes after the dyeing process.
Bioengineering bacteria and is one way to reduce the environmental impact of dye production, since it can reduce the amounts of dangerous chemicals needed in the process. In a recent study published in ACS Sustainable Chemistry & Engineering, DNA into a type of bacterium, Corynebacterium glutamicum, that already produces the building blocks of the blue dye, . The specific segment of DNA, a "blue-pigment indigoidine synthetase" gene, allowed the bacteria to put those building blocks together. The bacteria produced large amounts of the dye, which the scientists then used to color white cotton.
If scientists can engineer bacteria that produce dye at a level comparable to industry, we could see a shift towards the use of these greener methods in the textile industry. This will lead to greater sustainability in an unsustainable industry.
