Afifella is a photoheterotrophic genus in the phylum Proteobacteria (Bacteria).[1][2]

Etymology

The generic name Afifella derives from S. Afif, British philosopher and painter, in recognition of his expertise and guidance in the subject of the philosophical tendency of structuralism, essential for the development and understanding of taxonomy as a science.[3]

Species

The genus contains two species:[3][4]

  • A. marina ((Imhoff 1984) Urdiain et al. 2009; Latin marina meaning marine), was previously known as Rhodobium marinum and before that as Rhodopseudomonas marina.
  • A. pfennigii ( (Caumette et al. 2007) Urdiain et al. 2009, ; New Latin pfennigii, of Pfennig, named after Norbert Pfennig, a German microbiologist) was previously known as Rhodobium pfennigii
gollark: There are intermediate classes between M (red dwarf) and G (our sun, roughly).
gollark: If you remove *some* amount, I don't know.
gollark: If you remove a lot it would cool down and become a red dwarf.
gollark: Similarly to biological life stars run on internal feedback loops; if fusion produces less heat the radiation pressure keeping the outer layers up is reduced so the core contracts and more stuff can fuse.
gollark: Oxygen CAN fuse in stars, it just requires higher pressure and temperatures.
