About the Company
Founded in 2008, AMSilk developed a patented, animal-free process to produce spider silk protein using genetically engineered microbes.
AMSilk presented Biosteel® fiber in 2013. Biosteel is spider silk protein produced by genetically engineered microbes and spun into fiber.
Biosteel® fiber is microbe-derived. The gene that codes for spider silk protein is first inserted into bacteria. The engineered bacteria are placed in large bioreactor tanks with the necessary growth medium. The proteins produced by the bacteria are harvested and processed into fibers.
Fashion and accessories, footwear, home goods, and automotive. Performance shoe by Adidas made from Biosteel fiber in 2016.
