Partnership spins new chapter for ‘spider silk’ proteins

22/01/2024
Germany-based synthetic silk developer AMSilk has teamed up with Swedish bioproduction group 21st.BIO to ramp up its “spider silk”-like protein production. 

21st.BIO's scientists have developed new production strains, fermentation and processes to boost production and significantly reduce unit costs. 

This will enable AMSilk to further broaden its portfolio into different types of fibres and proteins, the companies said.

Gudrun Vogtentanz, chief scientific officer at AMSilk, said: "AMSilk's protein-based products unlock the secrets of spider silk to create engineerable structures and solutions. Through 21st.BIO, we now have access to more efficient production strains, which are a game changer in terms of the efficiency and sustainability of our feedstock. 

“Moving production quantities from kilos to tonnes brings AMSilk's technology to the next level. This collaboration with 21st.BIO is key to accelerating time-to-market for AMSilk in the current scale-up phase."

AMSilk's proteins are biodegradable and biocompatible and are based on a renewable plant-based feedstock.

Launched in 2015, AMSilk's material has found applications in sportswear and footwear.
