Alive biodegradable textiles can host engineered microbes to change color and add UV protection

Fashion has a problem it keeps trying to solve with chemistry. Most textiles are designed to look good, perform under stress, and then disappear as little as possible. The breakthrough described in Scientific American flips the script: a biodegradable textile can be alive, and it can host engineered microbes. Those microbes can be programmed to do practical things, like changing the fabric's color or adding UV protection.

That combination matters because it merges two directions the industry has pursued in parallel but rarely under one roof. Color and performance typically come from durable chemical treatments or dyes, while biodegradability is often engineered at the fiber level.
