Methanogenium boonei is a methanogenic archaean. Cells are non-motile irregular cocci 1.0-2.5 μm in diameter. This mesophile grows optimally at 19.4 °C, pH6.4-7.8, salinity 0.3-0.5M Na+. It was first isolated from Skan Bay, Alaska.
Aeropyrum pernix is a species of extremophile archaean in the archaean phylum Crenarchaeota. It is an obligatorily thermophilic species. The first specimens were isolated from sediments in the sea off the coast of Japan.
Sulfurimonas is a bacterial genus within the class of Epsilonproteobacteria, known for reducing nitrate, oxidizing both sulfur and hydrogen, and containing Group IV hydrogenases. 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”. The size of the bacteria varies between about 1.5-2.5 μm in length and 0.5-1.0 μm in width. Members of the genus Sulfurimonas are found in a variety of different environments which include deep sea-vents, marine sediments, and terrestrial habitats. Their ability to survive in extreme conditions is attributed to multiple copies of one enzyme. 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. Deep ocean currents affect the dispersal of Sulfurimonas spp., influencing its speciation. As shown in the MLSA report of deep-sea hydrothermal vents Epsilonproteobacteria, Sulfurimonas has a higher dispersal capability compared with deep sea hydrothermal vent thermophiles, indicating allopatric speciation.
Roseomonas lacus is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pale pink-colored bacterium. It was first isolated from a freshwater sediment from Lake Tai in Jiangsu province, China, and the species was first proposed in 2006. The species name comes from Latin lacus (lake).

The species name comes from Latin suffusca (brownish), referring to the color that the bacterial colonies form, as opposed to the pink coloration of most members of the genus Roseomonas.
