Researchers can harvest protein and vitamin B9 from microbes by feeding them nothing much more than hydrogen, oxygen, and CO2. The technology runs on renewable energy to produce a sustainable, micronutrient-enriched protein alternative that may one day make it to our plates.
Researchers in Germany can harvest protein and vitamin B9 from microbes by feeding them nothing much more than hydrogen, oxygen, and CO, runs on renewable energy to produce a sustainable, micronutrient-enriched protein alternative that may one day make it to our plates.
The team designed a two-stage bioreactor system that produces yeast rich in protein and vitamin B9. This vitamin is also known as folate and is essential for bodily functions like cell growth and metabolism. In the first stage, the bacterium, more commonly known as baker's yeast, feeds on acetate and oxygen to make protein and vitamin B9. The hydrogen and oxygen can be produced by zapping water with electricity produced by clean energy sources like windmills, for example.
This technology aims to address several global challenges: environmental conservation, food security, and public health. Running on clean energy and CO, the system reduces carbon emissions in food production. It uncouples land use from farming, freeing up space for conservation. Angenent also stresses that it will not outcompete farmers. Instead, the technology will help concentrate farmers to produce vegetables and crops sustainably.
