Aciduliprofundum Boonei
"''Candidatus'' Aciduliprofundum boonei" is an obligate Thermoacidophile, thermoacidophilic candidatus, candidate species of archaea belonging to the phylum "Euryarchaeota". Isolated from acidic hydrothermal vent Environment (biophysical), environments, "''Ca.'' A. boonei" is the first cultured representative of a biogeochemistry, biogeochemically significant clade of thermoacidophilic archaea known as the "Deep-Sea Hydrothermal Vent Euryarchaeota 2, Deep-Sea Hydrothermal Vent Euryarchaeota 2 (DHVE2)". Cell morphology and physiology "''Ca.'' A. boonei" is an obligate thermoacidophile capable of growing at pH 3.3-5.8, with its optimum zone being 4.2-4.8. Cultures have been shown to grow between 55 and 77 °C with best growth occurring at 70 °C with a 2.5-3.5% (w/v) Sodium chloride, NaCl optimum. Morphologically, the archaeon has been described as a Pleomorphism (microbiology), pleiomorphic coccus with a diameter of 0.6-1.0μm, that is motile via a singular, proximally s ...

Transmission Electron Micrograph
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron microscopy is a major analytical method i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
