Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Methanotrophs are prokaryotes that metabolize methane as their source of carbon and chemical energy. They are bacteria or archaea, can grow aerobically or anaerobically, and require single-carbon compounds to survive.
Venenivibrio stagnispumantis strain CP.B2 is the first microorganisms isolated from the terrestrial hot spring Champagne Pool in Waiotapu, New Zealand.
Methylocella silvestris is a bacterium from the genus Methylocella spp which are found in many acidic soils and wetlands. Historically, Methylocella silvestris was originally isolated from acidic forest soils in Germany, and it is described as Gram-negative, aerobic, non-pigmented, non-motile, rod-shaped and methane-oxidizing facultative methanotroph. As an aerobic methanotrophic bacteria, Methylocella spp use methane (CH4), and methanol as their main carbon and energy source, as well as multi compounds acetate, pyruvate, succinate, malate, and ethanol. They were known to survive in the cold temperature from 4° to 30° degree of Celsius with the optimum at around 15° to 25 °C, but no more than 36 °C. They grow better in the pH scale between 4.5 to 7.0. It lacks intracytoplasmic membranes common to all methane-oxidizing bacteria except Methylocella, but contain a vesicular membrane system connected to the cytoplasmic membrane. BL2T (=DSM 15510T=NCIMB 13906T) is the type strain.
Methylocella palustris is a species of bacterium. It is notable for oxidising methane. It is acidophilic and was first found in a peat bogs, representing a novel subtype of serine-pathway methanotrophs, for which a new genus was described. It is aerobic, Gram-negative, colourless, non-motile and its cells can be straight or curved rods. Strain KT is the type strain.
Ferroplasma acidiphilum is an acidophilic, autotrophic, ferrous iron-oxidizing, cell wall-lacking, mesophilic member of the Ferroplasmaceae. F. acidophilum is a mesophile with a temperature optimum of approximately 35 °C, growing optimally at a pH of 1.7. F. acidophilum is generally found in acidic mine tailings, primarily those containing pyrite (FeS2). It is especially abundant in cases of severe acid mine drainage, where other organisms such as Acidithiobacillus and Leptospirillum lower the pH of the environment to the extent that F. acidophilum is allowed to flourish.
Bryocella elongata is a bacterium, a type species of genus Bryocella. Cells are Gram-negative, non-motile pink-pigmented rods that multiply by normal cell division and form rosettes. The type strain is SN10(T). B. elongata was first isolated in 2011 from a methanotropic enrichment culture.
Methylocella tundrae is a species of bacterium. It is notable for oxidising methane. Its cells are aerobic, Gram-negative, non-motile, dinitrogen-fixing rods. Strain T4T is the type strain.
Methylocapsa is a genus of bacteria from the family of Beijerinckiaceae. M. gorgona has been shown to metabolize significant amounts of atmospheric methane.
Rhodoblastus sphagnicola is a rod-shaped bacteria with a polar flagella from the genus Rhodoblastus which was isolated from acidic Sphagnum peat from Sosvyatskoe bog in the Tver Region in the West Dvinskiy district in Russia.
Methylocystis heyeri is a Gram-negative, aerobic, methanotrophic and non-motile bacterium species from the genus of Methylocystis that has been isolated from Sphagnum peat in the Großer Teufelssee in Germany.
Methyloferula is a Gram-negative, mesophilic, psychrotolerant, aerobic and colorless genus of bacteria from the family of Beijerinckiaceae. Up to now there is only one species of this genus known.
Methyloferula stellata is a Gram-negative and non-motile bacteria from the genus of Methyloferula which has been isolated from acidic peat soil from Arkhangelsk in Russia. In contrast to most known Methanotrophs Methyloferula stellata is an aerobic acidophilic methanotroph. This makes it similar to Methylocella species, however it is unable to grow on multicarbon substrates. It's genome was sequenced in March and April 2015.
Mucilaginibacter gracilis is a Gram-negative, facultatively aerobic, heterotrophic and non-motile bacterium from the genus of Mucilaginibacter which has been isolated from Sphagnum peat bog in the Tomsk Region in Russia.
Mucilaginibacter paludis is a facultatively aerobic and heterotrophic bacterium from the genus of Mucilaginibacter which has been isolated from acidic Sphagnum peat bog in western Siberia in Russia. Mucilaginibacter paludis has the ability to degrade pectin, xylan and laminarin.
Acidithrix ferrooxidans is a heterotrophic, acidophilic and Gram-positive bacterium from the genus Acidithrix. The type strain of this species, A. ferrooxidans Py-F3, was isolated from an acidic stream draining from a copper mine in Wales. This species grows in a variety of acidic environments such as streams, mines or geothermal sites. Mine lakes with a redoxcline support growth with ferrous iron as the electron donor. "A. ferrooxidans" grows rapidly in macroscopic streamer, producing greater cell densities than other streamer-forming microbes. Use in a bioreactors to remediate mine waste has been proposed due to cell densities and rapid oxidation of ferrous iron oxidation in acidic mine drainage. Exopolysaccharide production during metal substrate metabolism, such as iron oxidation helps to prevent cell encrustation by minerals.
Lebetimonas acidiphila is a thermophilic, acidophilic, hydrogen-oxidizing and motile bacterium from the genus of Lebetimonas. To observe growth there temperature should be between 30 and 68 degrees Celsius.
Singulisphaera is a moderately acidophilic and mesophilic genus of bacteria from the family of Planctomycetaceae.
Singulisphaera acidiphila is an aerobic and non-motile bacterium from the genus of Singulisphaera which has been isolated from Sphagnum peat from the Yaroslavl Region in Russia.
Singulisphaera rosea is a moderately acidophilic, mesophilic, aerobic and non-motile bacterium from the genus of Singulisphaera which has been isolated from Sphagnum peat from the Tver Region in Russia.
