AMSilk is a German company that uses genetically engineered e. coli bacteria to produce silk proteins.
AMSilk produced fibers for Adidas shoes. The fibers used to produce the shoes are made of the same protein that spiders use to make silk. However, the material itself is made by engineered bacteria in large bioreactor tanks.
Medical implant coating
Because it is made of proteins that the immune system isn't inclined to fight, spider silk can be used to make a protective coating for medical implants. AMSilk has developed a coating for breast implants using artificial silk. The silk coating allows the body to adjust to the implant by forming a capsule of tissue around it.
