Photosynthetic Microorganisms for Sustainable Space Agriculture

What is it about?

This review discusses the potential use of photosynthetic microorganisms for agriculture in closed environments, such as space colonization. The space environment is extreme for plant growth and survival due to factors like gravity, radiations, light spectrum, and temperature. Photosynthetic microorganisms can produce secondary metabolites, like exopolysaccharides and indole alkaloids, that can stimulate plant growth and improve crop yields. These microorganisms could also be used to produce oxygen and recycle waste materials. The review highlights the advantages of using photosynthetic microorganisms, including cyanobacteria, in space agriculture for better plant growth and plant stimulation.
