Researchers have identified a novel microbial species found aboard the China Space Station, named Niallia tiangongensis. The discovery was made possible through the space station’s engineering and aerospace technology experimental program.
The Shenzhou-15 astronaut crew collected microbial samples from cabin surfaces in orbit, which were then transported back to Earth for analysis. Through morphological observation, genome sequencing, phylogenetic analysis, and metabolic profiling, researchers confirmed the existence of the novel species.
Niallia tiangongensis excels at adapting to space conditions. It has an exceptional ability to withstand stress by regulating biosynthesis, maintaining cellular redox balance under extreme conditions. The microbe also exhibits unique traits in biofilm formation and radiation damage repair.
The discovery’s survival strategies offer new insights for researchers. Its mechanisms can help design targeted microbial control strategies, providing ideas for fields such as aerospace, agriculture, industry, and medicine. Additionally, its ability to utilize certain organic compounds opens up possibilities for sustainable use on Earth.
As the space station continues its long-term operations, ongoing studies of microbial substances, genetic resources, and metabolic functions are expected to produce significant results, bringing new opportunities for scientific research and practical applications on Earth.
