Nitrosomonadaceae
The ''Nitrosomonadales'' are an order of the class ''Betaproteobacteria'' in the phylum ''Pseudomonadota''.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . Like all members of their class, they are Gram-negative. The order is divided into six families: * '' Nitrosomonadaceae'' (type family) comprises the genera ''Nitrosomonas'' (type genus), '' Nitrosolobus'' and '' Nitrosospira''. * ''Methylophilaceae'' comprises the genera '' Methylophilus'' (type genus), ''Methylobacillus'' and '' Methylovorus''. * '' Spirillaceae'' comprises the genus '' Spirillum'' (type genus) * '' Thiobacillaceae'' comprises the genera ''Thiobacillus'' (type genus), '' Annwoodia'', '' Sulfuritortus''. * '' Gallionellaceae'' comprises the genera '' Gallionella'' (type genus), '' Ferriphaselus'', '' S ...

Betaproteobacteria
''Betaproteobacteria'' are a class of Gram-negative bacteria, and one of the six classes of the phylum '' Pseudomonadota'' (synonym Proteobacteria). Metabolism The ''Betaproteobacteria'' comprise over 75 genera and 400 species. Together, they represent a broad variety of metabolic strategies and occupy diverse environments, ranging from obligate pathogens living within host organisms to oligotrophic groundwater ecosystems. Whilst most members of the ''Betaproteobacteria'' are heterotrophic, deriving both their carbon and electrons from organocarbon sources, some are photoheterotrophic, deriving energy from light and carbon from organocarbon sources. Other genera are autotrophic, deriving their carbon from bicarbonate or carbon dioxide and their electrons from reduced inorganic ions such as nitrite, ammonium, thiosulfate or sulfide — many of these chemolithoautotrophic. ''Betaproteobacteria'' are economically important, with roles in maintaining soil pH and in elementa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrosomonas
''Nitrosomonas'' is a genus of Gram-negative bacteria belonging to the class Betaproteobacteria. It is one of the five genera of ammonia-oxidizing bacteria and, as an obligate chemolithoautotroph, uses ammonia (NH3) as an energy source and carbon dioxide (CO2) as a carbon source in the presence of oxygen. ''Nitrosomonas'' are important in the global biogeochemical nitrogen cycle, since they increase the bioavailability of nitrogen to plants and in the denitrification, which is important for the release of nitrous oxide, a powerful greenhouse gas. This microbe is photophobic, and usually generate a biofilm matrix, or form clumps with other microbes, to avoid light. ''Nitrosomonas'' can be divided into six lineages: the first one includes the species '' Nitrosomonas europea'', '' Nitrosomonas eutropha'', '' Nitrosomonas halophila'', and '' Nitrosomonas mobilis.'' The second lineage presents the species '' Nitrosomonas communis'', ''N. sp. I'' and ''N. sp. II.'' The third line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Denitratisoma
''Denitratisoma'' is a genus in the phylum Pseudomonadota (Bacteria). Etymology The name ''Denitratisoma'' derives from:Latin pref. ''de''-, away from; Neo-Latin noun ''nitras'' -''atis'', nitrate; Greek neuter gender noun ''soma (σῶμα)'', body; Neo-Latin neuter gender noun ''Denitratisoma'', a body that reduces nitrate. Species The genus contains a single species, namely '' D. oestradiolicum'' ( Fahrbach ''et al''. 2006, (Type species of the genus).; Neo-Latin noun ''oestradiol'', oestradiol; Latin neuter gender suff. -''icum'', belonging to; Neo-Latin neuter gender adjective ''oestradiolicum'', belonging to oestradiol, referring to oestradiol utilization.)
