In industrial biotechnology, the real challenge isn’t discovery: it’s delivery. At 21st.BIO, we help companies bridge the gap between lab success and large-scale production.

We provide the full technology package for precision fermentation of proteins and peptides: highly productive microbial strains, optimized fermentation processes, and downstream workflows built for scalability. Our technology builds on more than 40 years of strain and process engineering from Novo Nordisk and Novonesis – refined and expanded at 21st.BIO to make industrial-scale production accessible.

We collaborate globally with start-ups and established manufacturers through two models: shared development programmes for nature-identical molecules, and bespoke projects for exclusive protein assets. By enabling efficient, cost-competitive fermentation, we empower our partners to bring sustainable protein innovations to market considerably faster and at lower risk.
