Afifella pfennigii is a bacterial species from the genus Afifella which has been isolated from benthic microbial mat from a brackish water pond on the Rangiroa Atoll on the French Polynesia Islands. [1] [2]

Afifella is a photoheterotrophic genus in the phylum Proteobacteria (Bacteria).

Microbial mat

A microbial mat is a multi-layered sheet of microorganisms, mainly bacteria and archaea. Microbial mats grow at interfaces between different types of material, mostly on submerged or moist surfaces, but a few survive in deserts. They colonize environments ranging in temperature from –40 °C to 120 °C. A few are found as endosymbionts of animals.

Brackish water Water with salinity between freshwater and seawater

Brackish water is water having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root "brak". Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment.

Rhodobium is a genus of purple non-sulfur bacteria. The cells are rod-shaped and reproduce by budding, as in many other members of the Rhizobiales. RNA trees separate it from the others, however, and it is given its own family. R. orientis, the type species, was isolated from seawater in 1995. It is capable of photosynthetic hydrogen production via the nitrogenase enzyme.

In taxonomy, Methanobacterium is a genus of the Methanobacteriaceae. Contrary to their name, they are not exactly a bacterial species as they belong to the archaea and have the distinguishing biopolymer, peptidoglycan, missing from their cell membranes. Methanobacterium are nonmotile and live without oxygen. Some members of this genus can use formate to reduce methane; others live exclusively through the reduction of carbon dioxide with hydrogen. They are ubiquitous in some hot, low-oxygen environments, such as anaerobic digestors, their wastewater, and hot springs.

Oxobacter is a genus of Gram-positive obligately anaerobic rod-shaped acetogenic bacteria. The sole species in the genus is Oxobacter pfennigii, formerly known as Clostridium pfennigii. This endospore-forming microorganism catabolizes pyruvate to acetate and CO2, while sugars and amino acids are not utilized as energy sources.

Pseudonocardia is the type genus of the bacteria family Pseudonocardiaceae. Members of this genus have been found living mutualistically on the cuticle of the leafcutter ants because the bacteria has antibiotic properties that protect the fungus grown by the ants. The bacteria may also be found in crypts on the propleural plate.

Coprothermobacter is a genus of rod-shaped microorganisms, belonging to the new bacterial family Coprothermobacteraceae of the new phylum Coprothermobacterota. This taxonomic genus has been reclassified in 2018, after different phylogenetic studies showed that these bacteria represented a deeply branched taxon of the domain Bacteria ; consequently, the clade including this genus has been classified in a separate phylum from Firmicutes, the phylum where it was included before reclassification.

Digital object identifier Character string used as a permanent identifier for a digital object, in a format controlled by the International DOI Foundation

In computing, a Digital Object Identifier or DOI is a persistent identifier or handle used to uniquely identify objects, standardized by the International Organization for Standardization (ISO). An implementation of the Handle System, DOIs are in wide use mainly to identify academic, professional, and government information, such as journal articles, research reports and data sets, and official publications though they also have been used to identify other types of information resources, such as commercial videos.
