Sulfurospirillum ( ) is a genus of the gram-negative, aerotolerant, rod-shaped bacteria in the family Campylobactaeraceae.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
Unassigned Sulfurospirillum species:
Many species are microaerophillic, and are thus found in soil, groundwater, the deep sea, marine surface sediments, tube worm guts, and polluted environments. Many species can grow on toxic compounds such as arsenate and selenate, and in fact flourish in contaminated sites. Some species can respire organohalides. No species in the Sulfurospirillum genus have been found to be pathogenic thus far.
