Sulfurimonas is a bacterial genus within the class Epsilonproteobacteria. The members of this group grow chemolithoautotrophically using zero valent sulfur, molecular hydrogen or reduced sulfur compounds as electron donors and nitrate, nitrite and oxygen as electron acceptors. CO2 is used as the sole carbon source. Habitats where representatives of Sulfurimonas have been isolated from included coastal sediments and hydrothermal vents.[2]

Described members of genus

  1. Sulfurimonas autotrophica[3]
  2. Sulfurimonas denitrificans[2] (Previously known as Thiomicrospira denitrificans[4])
  3. Sulfurimonas gotlandica[5]
  4. Sulfurimonas paralvinellae[6]

Environmental relevance

In order to grow, Sulfurimonas species consume both reduced sulfur species and oxidized nitrogen species (see above). Therefore, members of Sulfurimonas directly affect biogeochemical cycling of these elements in environments where they exist and are numerically abundant. For example, Sulfurimonas gotlandica may account for up to 25% of the microbial community in the Baltic sea redoxcline based on CARD-FISH cell counts [5] and Sulfurimonas spp. accounted for a significant number of the Epsilonproteobacterial reads in a survey of microbial diversity at deep-sea diffuse flow vents using amplified 16S sequences.[7]
