Who needs cotton? Simply mix together some yeast, a little bacteria and a few cups of sweet green tea, and you can grow your own garments. BioCouture is using microbes to create a textile biomaterial that can actually be molded into clothing. How does it work? The yeasty mixture sprouts fibers that eventually form thin sheets of bacterial cellulose that can be molded into jackets, dresses and other types of clothing. As the sheets dry, their overlapping edges fuse together, forming seams, and when all the fibers have dried, the garment can be colored with vegetable dyes. BioCouture says the material feels similar to vegetable leather, and just like your vegetable peelings, the clothing can be composted when you no longer want it.
