claimMosses and biocrusts, which are composed of cyanobacteria, green algae, lichens, fungi, and bryophytes, are considered promising candidates for early-stage ecological engineering on Mars due to their resilience and functional versatility.
claimCyanobacteria and microalgae are considered promising chassis for in situ resource utilization on Mars, specifically for oxygen production, CO₂ fixation, and primary biomass generation.
referenceCyanobacterium-based life-support systems are suitable for operation in a low-pressure, N2/CO2 atmosphere, which is relevant for Mars, according to the 2021 study 'A low-pressure, N2/CO2 atmosphere is suitable for Cyanobacterium-based life-support systems on Mars' published in Frontiers in Microbiology.
procedureControlled indoor microbial systems for Mars involve cultivating autotrophic organisms like cyanobacteria, algae, or fungi in closed-loop bioreactors or greenhouses to provide oxygen, recycle nutrients, and produce biomaterials such as carbonate bricks or fungal mycelium-based composites.
claimActively selected or genetically modified cyanobacteria capable of fixing nitrogen under very low atmospheric availability are proposed as potential tools for terraforming Mars.
