Understanding the characteristics of microbes during long-term space missions is essential for safeguarding health astronauts and maintaining functionality spacecraft. In this study, a Gram-positive, aerobic, spore-forming, rod-shaped strain JL1B1071 T was isolated from surface hardware on China Space Station. This belongs to genus Niallia , with its closest relative being circulans ATCC 4513 . The genome 5 166 230 bp in size, G+C content 35.6 mol%. average nucleotide identity digital DNA–DNA hybridization values between N. are 83.3 27.5%, respectively, both below recommended thresholds species delineation. major cellular fatty acids were anteiso-C 15:0 iso-C quinone menaquinone-7 (MK-7). Notably, demonstrates unique ability hydrolyse gelatin, suggesting that it can utilize gelatin as substrate nutrient-limited environments. Genomic analysis revealed two conserved signature indels GAF domain-containing protein DNA ligase D protein, which specific Additionally, structural functional differences proteins BshB1 SplA identified, may enhance biofilm formation, oxidative stress response radiation damage repair, thereby aiding survival environment. Based phenotypic, physiological chemotaxonomic characteristics, well annotation, considered novel within proposed be named tiangongensis sp. nov. type (=GDMCC 1.4642=KCTC 43715).
