Legume-Rhizobia Mars Simulant Symbiosis

+

A model legume-rhizobia nitrogen-fixing symbiosis tested for its ability to establish on Mars soil simulants. The community pairs the model legume Medicago truncatula with two of its symbiotic rhizobial partners, Sinorhizobium meliloti and Sinorhizobium medicae. Plants were grown on different grades of the Mojave Mars Simulant (MMS-1: Coarse, Fine, Unsorted, Superfine) and the MMS-2 simulant. Root nodules developed on M. truncatula roots grown on the Mars simulants comparably to plants grown on sand, and nifH (a reporter gene for nitrogen fixation) expression was detected inside the nodules, demonstrating that the simulants can support the legume-rhizobia symbiosis. Total plant mass was higher on MMS-2 than on MMS-1 and its grain-size variants, indicating that simulant chemical composition matters more than grain size; MMS-2 Superfine was recommended for future studies. The system is a model for beneficial plant-microbe associations enabling sustainable, nitrogen-fixing agriculture on Mars, exploiting the nitrogen present in the martian atmosphere. +

Mars Meteorite EETA79001 Microbial Growth Panel

+

A defined four-member panel of microorganisms tested for their ability to grow on actual martian regolith, supplied as sawdust of the Mars meteorite EETA79001, rather than on a terrestrial simulant. The panel comprises the bacterium Escherichia coli B, the two cyanobacteria Eucapsis sp. and Chroococcidiopsis sp. strain Chr20-20201027-1, and the cold-adapted bacterium Planococcus halocryophilus. Each organism was cultivated separately on EETA79001 sawdust for up to 23 days under terrestrial conditions across regolith:water ratios from 4:1 to 1:10; the study demonstrates that real martian regolith can support microbial growth and does not contain bactericidal agents. The panel is an astrobiology / In-Situ Resource Utilization model relevant to putative martian life and to bio-sustainable human habitats on Mars. Members were assayed individually, so the record captures a shared capacity to grow on martian regolith rather than measured interspecies interactions. +

Mars Regolith Cyanobacteria/Microalga Biofertilizer Panel

+

A defined four-member panel of photosynthetic microorganisms evaluated for their ability to grow using only martian resources (water and Mars Global Simulant MGS-1 regolith extract) under an Earth-like atmosphere, as candidates to support Mars colonization through oxygen and biomass production. The panel comprises three cyanobacteria — Anabaena cylindrica, Nostoc muscorum (NCBI Taxonomy: Desmonostoc muscorum), and Arthrospira platensis (NCBI Taxonomy: Limnospira platensis) — and the green microalga Chlorella vulgaris. Each species was grown separately in a martian regolith extract culture medium and monitored for 25 days by optical density and fluorometric parameters; Nostoc muscorum grew best, while Arthrospira platensis and Chlorella vulgaris did not thrive on the regolith extract. End-of-life biomass was then tested as a biofertilizing agent for the macrophyte Lemna minor, stimulating plant biomass to levels comparable to standard synthetic medium. The panel is an In-Situ Resource Utilization model for bioregenerative life support on Mars. Members were assayed individually, so the record captures a shared capacity to grow on martian regolith resources rather than measured interspecies interactions. +

Moss-Microbe Complex Regolith Biofertilizer

+

A moss-microbe complex evaluated as a bio-based biofertilizer for improving crop growth on lunar and Martian soil simulants. The complex comprises the moss Hypnum plumaeforme together with plant growth-promoting bacteria isolated from it — Pseudomonas monteilii and Bacillus cereus — selected for phosphate solubilization, indole-3-acetic acid (IAA) production, and siderophore synthesis. Using barley (Hordeum vulgare) as a model crop, the study compared moss alone, microbes alone, and their combined application under extreme edaphic conditions represented by lunar (LHS) and Martian (MGS) soil simulants. The moss-microbe co-treatment significantly enhanced shoot biomass, dry weight, organic matter, available phosphate, and cation exchange capacity; in the dense, low-porosity Martian simulant the moss functioned as a biological buffer that facilitated microbial colonization and restored plant growth. 16S rRNA profiling confirmed the stable presence of the genera Pseudomonas, Bacillus, and Devosia in moss-treated soils, and metabolite profiling revealed accumulation of growth-related compounds (D-ribose, D-gluconate), suggesting the complex reprograms rhizosphere metabolism. The system is an In-Situ Resource Utilization model for extraterrestrial farming and land restoration. +

A moss-microbe complex evaluated as a bio-based biofertilizer for improving crop growth on lunar and Martian soil simulants. The complex comprises the moss Hypnum plumaeforme together with plant growth-promoting bacteria isolated from it — Pseudomonas monteilii and Bacillus cereus — selected for phosphate solubilization, indole-3-acetic acid (IAA) production, and siderophore synthesis. Using barley (Hordeum vulgare) as a model crop, the study compared moss alone, microbes alone, and their combined application under extreme edaphic conditions represented by lunar (LHS) and Martian (MGS) soil simulants. The moss-microbe co-treatment significantly enhanced shoot biomass, dry weight, organic matter, available phosphate, and cation exchange capacity; in the dense, low-porosity Martian simulant the moss functioned as a biological buffer that facilitated microbial colonization and restored plant growth. 16S rRNA profiling confirmed the stable presence of the genera Pseudomonas, Bacillus, and Devosia in moss-treated soils, and metabolite profiling revealed accumulation of growth-related compounds (D-ribose, D-gluconate), suggesting the complex reprograms rhizosphere metabolism. The system is an In-Situ Resource Utilization model for extraterrestrial farming and land restoration. +
