In order to withstand the rigors of space on deep-space missions, food grown outside of Earth needs a little extra help from bacteria. Now, a recent discovery aboard the International Space Station (ISS) has researchers may help create the ‘fuel’ to help plants withstand such stressful situations.
Publishing their findings to Frontiers in Microbiology, researchers working with NASA described the discovery and isolation of 4 strains of bacteria belonging to the family Methylobacteriaceae from different locations aboard the ISS across two consecutive flights.
While 1 strain was identified as Methylorubrum rhodesianum, the other 3 were previously undiscovered and belong to a novel species novel. The rod-shaped, motile bacteria were given the designations IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5 with genetic analysis showing them to be closely related to Methylobacterium indicum.

- 34Bacteria that move around live on the edge. All the time. Their success, be it in finding nutrients, fending off predators or multiplying depends on how efficiently they navigate through their confining microscopic habitats. Whether these habitats are in animal or plant tissues, in waste, or in other materials. In…
