HYDROCOW’s Opinion Paper in Trends in Biotechnology Now Published

We are delighted to announce that HYDROCOW’s opinion paper, “Food Production from Air: Gas Precision Fermentation with Hydrogen‑Oxidising Bacteria,” has now been published in Trends in Biotechnology and is available to read online.

The article explores how hydrogen‑oxidising bacteria (HOBs) can convert CO₂ and green hydrogen into biomass through gas fermentation — a process already proven feasible across a range of microbial species. This approach offers a transformative vision for sustainable food production by decoupling the protein supply chain from agriculture while dramatically reducing land and water use.

The paper highlights how advances in synthetic biology, metabolic engineering, and bioreactor design are accelerating the development of gas‑based precision fermentation. It also presents a forward‑looking framework for producing complex proteins, such as recombinant milk proteins, using engineered HOBs — showcasing the scientific foundations behind HYDROCOW’s mission to produce milk proteins from CO₂ and electricity.

This publication marks an important milestone for the HYDROCOW project, reflecting the collaborative work of researchers across Europe in pioneering new, carbon‑neutral approaches to food production.
