Bacillus nealsonii

Bacillus nealsonii is a species of bacteria first isolated from a spacecraft-assembly facility. Its spores are γ-radiation resistant. It is Gram-positive, facultatively anaerobic, rod-shaped and produces endospores. Its type strain is FO-92T (=ATCC BAA-519T =DSM 15077T).

This species has been recently transferred into the genus Niallia. The correct nomenclature is Niallia nealsonii.
