iss072e616432 (Feb. 11, 2025) --- NASA astronaut and Expedition 72 Commander Suni Williams displays production packs containing geneticallly engineered yeast and edible media for incubation to activate yeast growth. The BioNutrients investigation explores using the engineered yeast to produce on-demand nutrients and avoid vitamin deficiencies for crews on long-term missions. The samples are later frozen then returned to Earth to analyze their ability promote crew health and improve the preservation of probiotics.
