BEIJING – Chinese scientists have identified a previously unknown bacterial strain aboard the Tiangong Space Station, marking the first such finding within the nation’s orbital laboratory, state broadcaster CCTV reported.
The bacterium, designated Niallia tiangongensis, is detailed in a report published in the International Journal of Systematic adn Evolutionary Microbiology, which outlines the morphological, genomic, and phylogenetic analyses conducted on the microorganism.
Microbial monitoring Program in Space
According to the research,the strain was isolated from equipment surfaces within the space station as part of an ongoing microbiological monitoring program. This program aims to study how microorganisms evolve during extended space missions.
The discovery stems from the Chinese Space Station Habitable Area microbiome Program (Champ), an initiative focused on tracking microbial dynamics inside the orbital complex.
In May 2023, the Tiangong crew collected swab samples from various locations within the station. These samples were later frozen and returned to Earth for laboratory analysis, CCTV reported.

Niallia tiangongensis: unique Genetic Profile
Researchers employed whole-genome sequencing, high-resolution imaging, and comparative phylogenetic methods to classify the strain within the genus Niallia, belonging to the family Cytobacillaceae. Tho, the bacterium exhibits genetic distinctions from its closest known terrestrial relatives.
laboratory tests indicate that this spore-forming, rod-shaped bacterium possesses structural and functional variations in proteins associated with oxidative stress response and radiation damage repair.These adaptations may enhance its survival capabilities in the harsh space surroundings.
Implications for Space Exploration and Beyond
The CCTV report suggests that this discovery could aid in developing strategies for controlling microorganisms in confined environments like spacecraft. Moreover, it may have potential applications in agriculture, industry, and medicine.
The Tiangong Space Station is expected to remain operational for approximately a decade. As the International Space Station, a U.S.-led initiative from which China is excluded due to military ties within its space program, nears its planned retirement in 2030, Tiangong could become a primary orbital platform.
China has significantly invested in its space program, achieving milestones such as landing the Chang’e 4 probe on the far side of the Moon – a first in space exploration – and successfully reaching Mars, making it the third nation, after the former Soviet Union and the United States, to achieve this feat.
