Unibio makes high-protein animal feed from methanotrope bacterial biomass.

The Danish start-up Unibio, which ferments methane into proteins, has secured $70 million from Saudi Industrial Investment Group. Unibio will use the money to scale up production. The firm claims that its technology, which uses a continuous-harvesting loop system, can improve global food security because it does not require the use of arable land and consumes little water. Calysta, which has a similar technology, plans to build a plant producing 100,000 metric tons of protein per year in Saudi Arabia.
