Kraig Biocraft Laboratories Inc (KBLB)

[Esa]

"Kraig Biocraft Laboratories in Ann Arbor, MI, has taken a different approach to solving the problem of commercialization of spider silk. Rather than producing silk in bacteria or yeast, Kraig Biocraft has introduced modified spider silk genes into domesticated silkworms. This insect has been used for centuries to produce large amounts of silk fiber that can be efficiently and cost-effectively spun into cloth. The resulting product is a composite fiber known as Monster SilkTM, made up of both silkworm silk and spider silk proteins that is considerably more flexible and stronger than current commercial silk. While ramping up MonsterSilk production, Kraig Biocraft is also developing SpiderPillar, an essentially pure spider silk, as well as a third generation of fibers that goes beyond spider silk’s chemical, mechanical and physical properties to incorporate such things as antibacterial agents for medical use.
It is clear that a wide array of spider silk fibers and cloth will soon be made available for many applications, from recyclable clothing that reduces pollution by the textile industry, to light and durable vehicles, drug delivery, and many other medical applications. These synthetic biology companies are spinning a web of bright possibilities for the future."
