Umm, interesting but EWW!

Cotton is a living plant that we make clothing fibers out of. Flax used to make linen is the same. We wear leather which was originally the skin on a living animal for pete's sake. Even knowing all that, the production of this "fabric" kind of made me gag. 
Suzanne Lee, a senior researcher of fashion and textiles in London, is experimenting with a textile made from bacteria. (Sounds odd but that's not the gagging moment.) For what she calls BioCouture she pours into a tub a green tea solution, mixed with a sugar solution, and adds a yeast and bacteria culture. The bacteria eats the sugars and the bi-product is cellulose mat that rises to the top of the tub. The gross part is what this mat looks like before ring out and shape onto forms, dry, and cut out for sewing. 
I know you are curious so watch a short video here for her and some scientists explaining what they are working on and see the product for yourself.
Her website shows some products they've made and the dying they are doing with fruit and vegetable based dyes.
As research and experimentation, I find it fascinating but something that looks like a human flesh dress? ... "It rubs the lotion on the skin or else it gets the hose again."

Bacteria Excretions

In Architecture future, bacteria might be what holds our buildings together. Scientists and students are working on genetically modifying a bacteria normally found in soil to repair cracks in concrete. The bacteria that they are calling "BacillaFilla" consists of 3 types of cells; the calcium carbonate producers, the filaments, and the "glue" producers. The cells start working when they come into contact with concrete and the final product is a crack filler that is just as hard as the concrete and has thereby reconnected the structure.
And to make it even more sci-fi, when injected into a crack the bacteria swims down th crack, knows when it's hit the end because of something called "quorum sensing", then it knows when to stop working because of a built-in self destruct gene.
Of course if this other scientist with these students from this other school succeed  in creating "crack-proof" concrete with nanotechnology, then we won't need bacteria poo and all their hard bacteria research will be for naught.
