Halothiobacillaceae

Halothiobacillus is a genus in the class Gammaproteobacteria. Both species are obligate aerobic bacteria; they require oxygen to grow. They are also halotolerant; they live in environments with high concentrations of salt or other solutes, but don't require them in order to grow.

The Halothiobacillaceae are a family of halotolerant, mesophilic, and obligate chemolithoautotrophic organisms in the Chromatiales comprising the genus Halothiobacillus. It is closely related to the family Thioalkalibacteraceae of halophilic obligate autotrophs with distinct morphological and genomic features.
