well, lj rich has visited a lab in london which is only using 200 millilitres of water to dye a 1 kilogrames petri dishes to make colouring clothing more environmentally friendly. this could be the future of fashion — and it smells like beetroot. these beautiful designs were created by bacterial activity, no chemicals required. so how did you come across using bacteria to dye clothing? so when i was studying material futures at saint martins, i met professorjohn ward here at ucl, and he introduced me to a bacterium called streptomyces coelicolor. depending on how it is grown, where it's grown, the ph of that environment, we can produce something like a navy blue, a bright pink, and so we use all of these conditions as a design toolkit to influence our patterns and outcomes on the textile. the bacterium ferments in a small amount of sugar solution, which produces pigment directly onto fabric as the colony of microorganisms grow. like a brewery with yeast, natsai engineers the growing conditions to produce different varieties of colour. i am really interested in how technology is changing ho
