There's a specific type of biomass fermentation called gas fermentation, which allows for the creation of edible protein out of thin air. When I first heard about it, it sounded a bit like magic. Turns out it's done through growing Hydrogen-Oxidizing Bacteria (HOB) in a bioreactor. The inputs are:
- Hydrogen
- Oxygen
- Carbon dioxide
- Nitrogen
Are there any folks interested in this specific type of biomass fermentation? I know there are a number of companies in this space, with Solar Foods(🇫🇮) probably the most well known, but there's also Air Protein (🇺🇸), Farmless (🇳🇱) and Arkeon (🇦🇹). However, I've not seen anyone trying to do this open source in a home/kitchen lab yet.
