Substituting soy
A piece about researchers making protein-rich yeast biomass ‘out of thin air’ proved popular.
We talked to the Austrian team that has succeeded in feeding yeasts with CO2, enabling the development of a yeast biomass that can potentially be used as a sustainable alternative to agriculturally produced protein-rich feed sources such as soy.
The biomass, based on CO2 and other non-fossil resources, could be commercially available by early 2021, said the specialists.
