Sulfurimonas is a bacterial genus within the class of Campylobacterota, known for reducing nitrate, oxidizing both sulfur and hydrogen, and containing Group IV hydrogenases.[2][3][4] This genus consists of four species: Sulfurimonas autorophica, Sulfurimonas denitrificans, Sulfurimonas gotlandica, and Sulfurimonas paralvinellae. The genus' name is derived from "sulfur" in Latin and "monas" from Greek, together meaning a “sulfur-oxidizing rod”.[5] The size of the bacteria varies between about 1.5-2.5 μm in length and 0.5-1.0 μm in width.[6][7][4] Members of the genus Sulfurimonas are found in a variety of different environments which include deep sea-vents, marine sediments, and terrestrial habitats.[3] Their ability to survive in extreme conditions is attributed to multiple copies of one enzyme[further explanation needed].[3]Phylogenetic analysis suggests that members of the genus Sulfurimonas have limited dispersal ability and its speciation was affected by geographical isolation rather than hydrothermal composition[citation needed]. Deep ocean currents affect the dispersal of Sulfurimonas spp., influencing its speciation.[8] As shown in the MLSA report[further explanation needed] of deep-sea hydrothermal ventsCampylobacterota, Sulfurimonas has a higher dispersal capability compared with deep sea hydrothermal ventthermophiles, indicating allopatric speciation[verification needed].[8]
