Armatimonas Rosea
''Armatimonas rosea'' is a Gram-negative bacterium and also the first species to be characterized within the phylum Armatimonadota. The Armatimonadota were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to ''A. rosea's'' discovery. Discovery ''A. rosea'' was originally isolated from the rhizoplane of the aquatic plant ''Phragmites australis'' inhabiting a freshwater lake in the Yamanashi prefecture in Japan. Cultivation and isolation were completed in a low nutrient medium, DTS. Relatives The environmental 16S rRNA gene sequences belonging to the phylum ''Armatimonadota'' are currently sorted into six groups. Groups 2, 5, and 6 consist solely of sequences. Group 1 contains ''Armatimonas rosea'', Group 3 contains ''Chthonomonadetes calidirosea'', and Group 4 contains ''Fimbriimonas ginsengisoli''. ''Chthonomonas calidirosea'' strain T49T, an aerobic, saccharolytic, obligately thermophilic, motile, non- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armatimonadota
''Armatimonadota'' is a phylum of gram-negative bacteria. History ''Armatimonadota'' was originally described solely on the basis of environmental 16S rRNA gene clone sequences, and was temporarily titled candidate phylum OP10. However, in 2011 a bacterial strain belonging to the phylum was isolated from an aquatic plant in Japan. The species was named ''Armatimonas rosea'' and was the first member of its phylum, genus, and species. Members ''Armatimonas rosea'', an aerobic chemoheterotrophic bacterium, strain YO-36T, was isolated from rhizoplane of an aquatic plant (a reed, ''Phragmites australis'') inhabiting a freshwater lake in Japan. ''Chthonomonas calidirosea'', an aerobic, saccharolytic, obligately thermophilic, motile, non-spore-forming bacterium, strain T49(T), was isolated from geothermally heated soil at Hell's Gate, Tikitere, New Zealand.

Phragmites Australis
''Phragmites australis'', known as the common reed, is a species of plant. It is a broadly distributed wetland grass that can grow up to tall. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent studies have characterized morphological distinctions between the int ...

Yamanashi Prefecture
is a prefecture of Japan located in the Chūbu region of Honshu. Yamanashi Prefecture has a population of 817,192 (1 January 2019) and has a geographic area of 4,465 km2 (1,724 sq mi). Yamanashi Prefecture borders Saitama Prefecture to the northeast, Nagano Prefecture to the northwest, Shizuoka Prefecture to the southwest, Kanagawa Prefecture to the southeast, and Tokyo to the east. Kōfu is the capital and largest city of Yamanashi Prefecture, with other major cities including Kai, Minamiarupusu, and Fuefuki. Yamanashi Prefecture is one of only eight landlocked prefectures, and the majority of the population lives in the central Kōfu Basin surrounded by the Akaishi Mountains, with 27% of its total land area being designated as Natural Parks. Yamanashi Prefecture is home to many of the highest mountains in Japan, and Mount Fuji, the tallest mountain in Japan and cultural icon of the country, is partially located in Yamanashi Prefecture on the border with Shizuoka Prefect ...

Fimbriimonas Ginsengisoli
''Fimbriimonas ginsengisoli'' is a Gram-negative bacterium and the first representative of the class ''Fimbriimonadia'' within the phylum ''Armatimonadota''. The ''Armatimonadota'' were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to ''F. ginsengisoli's'' relative, ''Armatimonas rosea's'' discovery. Discovery ''F. ginsengisoli'' was originally isolated from a soil sample from a ginseng field in the Pocheon province, South Korea. Cultivation took place on one-half strength R2A agar. Relatives The environmental 16S rRNA gene sequences, belonging to the phylum ''Armatimonadota'' are currently sorted into six groups. Groups 2, 5, and 6 consist solely of sequences. Group 1 contains ''Armatimonas rosea'', Group 3 contains ''Chthonomonadetes calidirosea'', and Group 4 contains ''Fimbriimonas ginsengisoli''.

Chthonomonas Calidirosea
''Chthonomonas calidirosea'' is a Gram-negative bacterium and also the first representative of the new class Chthonomonadetes within the phylum Armatimonadota. The Armatimonadota were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to ''C. calidirosea's'' relative, ''Armatimonas rosea's'' discovery. It is now known that bacterial communities from geothermal environments, are generally constituted by, at least 5–10% of bacteria belonging to Armatimonadota. Discovery ''Chthonomonas calidirosea'' was originally isolated from geothermally heated soil at Hell's Gate, Tikitere, New Zealand. The soil was aseptically sampled at an approximate depth of 15 cm below the surface. The sampled soil had a pH of 4.3 and an ''in situ'' temperature of 55 °C. Relatives The environmental 16S rRNA gene sequences, belonging to the phylum ''Armatimonadota'' are currently sorted into six groups. Groups 2, 5, and 6 co ...

Phase-contrast
__NOTOC__ Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than a vacuum, interaction with the medium causes the wave amplitude and phase (waves), phase to change in a manner dependent on properties of the medium. Changes in amplitude (brightness) arise from the scattering and absorption of light, which is often wavelength-dependent and may give rise to colors. Photographic equipment and the human eye are only sensitive to amplitude variations. Without special arrangements, phase changes are therefore invisible. Yet, phase changes often convey important information. Phase-contrast microscopy is particularly important in biology. It reveals many cell (biology), cellular structures that are invisible with a brigh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
