The purpose of this session is to brainstorm about all the possible ways how cyanobacteria can help surviving in space. It was shown that cyanobacteria can survive in space for at least 2 years . Also, always have in mind the scheme below, which describes what cyanobacteria need to produce oxygen!

Picture taken from https://www.seas.ucla.edu/~pilon/Bioreactor.html.

Additional questions for brainstorming:
  • how can we collect the produced oxygen more efficiently?
  • how can we store the cyanobacteria or the oxygen long-term?
  • can we somehow upcycle the produced oxygen to form the sustainable microenvironment?
  • can we somehow genetically modify cyanobacteria to produce more oxygen with less resources?

The idea was described here.

Basically, you inject cyanobacteria, upconversion nanoparticles, and shine yourself with near-infrared light. That should be enough for
(1) the near-infrared to pass through the bones and tissues,
(2) reach the upconversion nanoparticles which absorb it and emit the light in the visible specter,
(3) which can then be used by cyanobacteria for photosynthesis.

We have water, CO2, and light source, so it should work, right?
