Archaebacteria are written in bold.
*Genera containing both facultative and obligately chemolithoautotrophic species.

In addition to the Proteobacteria, five Sulfobacillus species belong to the phylum
Firmicutes and five Sulfurihydrogenibium species belong to the phylum Aquificae .
Within the Archaea, Sulfurisphaera ohwakuensis , four Acidianus species and six
Sulfolobus species belong to the family Sulfolobaceae within the phylum
Crenarchaeota [ 49 ]. Haloalkaliphilic and neutrophilic halophilic chemolithoau-
totrophic SOB comprise four and seven different groups, respectively, within the
