As the distance and duration of space travel is extended, the storage of vitamins for astronauts becomes more difficult. To solve this problem, the Toulouse iGEM team is designing a co-culture system with yeast and clostridium to produce vitamin A in spaceship environments. In addition, they are using an optogenetic system to produce rose and lemon flavors. Join the Pittsburgh iGEM team as they learn more about their project and some of the challenges they have faced so far!
