German Scientists Convert CO2 into Protein and Vitamins Using Renewable Energy
A novel bioreactor process transforms carbon dioxide, hydrogen, and oxygen into nutrient-rich yeast, offering a sustainable alternative to traditional farming.
- The technology uses a two-stage bioreactor system to produce yeast high in protein and vitamin B9.
- Thermoanaerobacter kivui bacteria convert hydrogen and CO2 into acetate, which is then consumed by Saccharomyces cerevisiae yeast.
- The resulting yeast provides 61% of daily protein needs per 85 grams, outperforming traditional protein sources like beef and lentils.
- The process runs on renewable energy, reducing carbon emissions and eliminating the need for farmland.
- Researchers aim to optimize production, ensure food safety, and assess market interest before commercial availability.
