Europe EditionNew Strain of Bacteria Found on China’s Tiangong Space Station
- Chinese researchers discovered a new bacterial strain named Niallia tiangongensis aboard the Tiangong space station in 2023.
- The discovery emerged from an ongoing program that continuously monitors microbial changes throughout the extended operation of the China Space Station’s living quarters.
- Researchers used surface swabs collected by the Shenzhou-15 crew, analyzed with genome sequencing, imaging, and metabolic profiling to identify the Gram-positive, spore-forming, rod-shaped strain.
- The strain exhibits distinct structural and functional variations in the BshB1 and SplA proteins, which likely contribute to improved biofilm development, resilience against oxidative stress, and repair of radiation-induced damage, thereby supporting its ability to survive in the space environment.
- This finding suggests potential applications for targeted microbial control in aerospace, agriculture, medicine, and sustainable waste conversion both in orbit and on Earth.

A Bacterial Strain Detected on Board a Chinese Space Station
Shafaq News/ Chinese scientists announced the discovery of a new species of bacteria that normally lives on Earth, but was found on the Tiangong space station, indicating that studying it will contribute to protecting the health of astronauts. This strain, named "Nealia tiangonggensis," is a new species of known terrestrial bacteria and was discovered in a compartment inside the space station. A team from the Shenzhou Aerospace Biotechnology Gro…
