Researchers at the University of Tübingen in Germany have developed a new method that utilizes microorganisms to convert hydrogen, oxygen, and carbon dioxide into proteins and vitamin B9. This innovation aims to address global challenges such as environmental protection, food security, and public health by producing sustainable and nutrient-rich protein alternatives using renewable energy sources. The technology was recently featured in the Cell Press journal Trends in Biotechnology.
The research team designed a two-stage bioreactor system for this process. In the first stage, anaerobic bacteria convert hydrogen and carbon dioxide into acetate. In the second stage, brewer's yeast consumes acetate to produce proteins and vitamin B9. The entire process relies on clean energy to supply hydrogen and oxygen.
Research findings indicate that the vitamin B9 produced by yeast fed with acetate is equivalent to that produced by yeast fed with sugars. Moreover, the protein content of the yeast surpasses that of beef, pork, and fish, and even exceeds that of lentils.
