Background: Endolithic niches offer an ultimate refuge, supplying buffered conditions for microorganisms that dwell inside rock airspaces. Yet, survival and growth strategies of Antarctic endolithic microbes residing in Earths driest and coldest desert remains virtually unknown. Results: From 109 endolithic microbiomes, 4,539 metagenome-assembled genomes were generated, 49.3% of which were novel candidate bacterial species. We present evidence that trace gas oxidation and atmospheric chemosynthesis may be the prevalent strategies supporting metabolic activity and persistence of these ecosystems at the fringe of life and the limits of habitability. Conclusions: These results represent the foundation to untangle adaptability at the edge of sustainability on Earth and on other dry Earth-like planetary bodies such as Mars.

Members of the genus Marinomonas are known for their environmental adaptation and metabolically versatility, with abundant proteins associated with antifreeze, osmotic pressure resistance, carbohydrase and multiple secondary metabolites. Comparative genomic analysis focusing on secondary metabolites and orthologue proteins were conducted with 30 reference genome sequences in genus Marinomonas. In this study, a Gram-stain-negative, rod-shaped, non-agellated and strictly aerobic bacterium, designated as strain E8 T , was isolated from the red algae (Gelidium amansii) in the coastal of Weihai, China. Optimal growth of the strain E8 T was observed at temperatures 25-30 ℃, pH 6.5-8.0 and 1-3% (w/v) NaCl. The DNA G + C content was 42.8 mol%. The predominant quinone was Q-8 and the major fatty acids were C 16:0 , summed feature 3 and summed feature 8. The main polar lipids were phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). Based on data obtained from this polyphasic taxonomic study, strain E8 T belongs to a novel species of the genus Marinomonas, for which the name Marinomonas algarum is proposed. The type strain is E8 T (= KCTC 92201 T = MCCC 1K07070 T ).
