Spider Silk Fibers from Bolt Threads - Scalable Fiber Production and Silk-like Properties

摘要

At Bolt Threads we are making fibers for the textile industry that are inspired by natural protein polymeric materials. The myriad of unique properties and inherent environmental compatibility of these polymers is our motivation for developing a molecular biology platform that is capable of manufacturing these materials via large-scale fermentation. With genetic-level control over the amino acid sequence, we are capable of fine tuning the polymer processing windows and functional material properties. Today, we are capable of producing a recombinant spider silk protein at commercial scale and spin this material into filament and staple yarns. These filaments exhibit spider silk biomimicry and can be generated with high consistency and at large volumes. This first fiber demonstrates the baselined capability of our designer protein polymer pipeline.
