Fashion has a pollution problem — can biology fix it?

I've just watched a brilliant Ted talk by Natsai Audrey Chieza - a textile designer working with the bacteria Streptomyces coelicolor to produce pigments for dyes. Initial experiments have proved promising - with colour fast results produced on silk using only 200ml of water!

This is potentially an amazing alternative to polluting petrochemical dyes - I shall be following the project with great interest!
