AMSilk and 21st.BIO announce partnership to accelerate the production of advanced materials made from spider silk-based proteins
The new strain ensures extracellular expression of silk proteins, enabling manufacturing at unprecedented productivity levels due to higher yield and greater efficiency, thereby reducing production costs.
Due to its unique combination of strength and flexibility, spider silk is the gold standard of bio industrial materials. AMSilk's spider silk-based proteins are wholly biodegradable and biocompatible. Based on a renewable plant based feedstock, AMSilk fibers do not contain any substances of animal origin and come with a CO2 greenhouse gas emission reduction of up to 90% and more than 90% less land and water use compared to other protein fibers. Their high-performance qualities enable a wide range of applications in the textile, homecare, biomedical, and automobile industries.
As one of the world's first industrial scale suppliers of advanced materials made from spider silk-based proteins, AMSilk has been redefining the performance fiber category since 2015, with applications in footwear and garments, and even interior components for automobiles. With a strong patent portfolio, AMSilk is leading the discovery of performance materials based on spider silk proteins.
21st.BIO benefits from the most advanced precision fermentation technology platform in the industry, with production strains that have been perfected for over 40 years and used in dozens of products on the market today. Working in close collaboration with AMSilk, 21st.BIO's scientists have developed and optimized new production strains, fermentation and downstream processes to support upscaled production and significantly reduce unit costs. This will enable AMSilk to further broaden its portfolio into different types of fibers and proteins, with applications in the broader mid-market.

Global bioplastics production will more than triple until 2026, from around 2.4 million tons in 2021 to 7.5 million tons in 2026[1]. There is a rapidly growing need to adopt more environmental-friendly materials. AMSilk is helping to meet this need by using its outstanding proprietary technology platform for large volume proteins, designing and customizing material properties at a molecular level depending on the final application or properties required.
AMSilk has developed a wide range of use cases for its silk proteins, from developing the leading spinning process for silk protein fibers, to transforming proteins into silk beads, gels and solutions to unlock the power of their coating effects. AMSilk's silk protein-based fibers set completely new standards within the apparel industry, offering unbelievably broad performance characteristics, ranging from ultra fineness to extreme strength, making them ideal as premium, low carbon material alternatives. AMSilk has also entered the performance yarn segment with technical yarns for the automotive industry – reflected in its collaboration with Mercedes Benz . AMSilk's silk protein formulations bring exceptional filming properties to dishwashing and laundry care, providing outstanding performance benefits as a bioshield.
