Earlier this year, US biotech company Calysta announced its idea for the perfect salmon feed — made from methane — was becoming viable for production and now the research team behind the effort is giving details on how it works.

Scientists at the University of Nottingham’s Synthetic Biology Research Centre, who are working with Calysta and biotech company CHAIN Biotech, are working to develop microbial technology, which uses microorganisms to ferment methane gas into valuable nutritional supplements.

“We specialize in the use of fermentation of certain gases to produce sustainable industrial chemicals and biofuels and now through this project to produce vital feedstock ingredients like omega-3 fatt acids,” said Biology Research Centre Professor Nigel Minton.
