Solibacillus

Solibacillus is a genus of Gram positive, rod shaped, spore-forming bacteria.
The first member of "Solibacillus" was first isolated in 1999, and was originally called "Bacillus silvestris". However, further studies on "B. silvestris" found that the organism belonged in a separate genus. "Solibacillus silvestris" was proposed, referring to its original designation as a member of "Bacillus", and the fact that the species was first isolated from soil. "Bacillus isronensis" was later reclassified as "Solibacillus isronensis". "S. isronensis" was isolated from cryotubes that were used to collect air samples from high altitudes, and "S. kalamii" was found in an air filter from the International Space Station.
