Archaea were initially classified as bacteria, receiving the name archaebacteria (/ ˌ ɑːr k i b æ k ˈ t ɪər i ə /, in the Archaebacteria kingdom), but this term has fallen out of use. [5] Archaeal cells have unique properties separating them from Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla.
Haloquadratum walsbyi is a species of Archaea in the genus Haloquadratum, known for its square shape and halophilic nature. [1]First discovered in a brine pool in the Sinai peninsula of Egypt, H. walsbyi is noted for its flat, square-shaped cells, and its unusual ability to survive in aqueous environments with high concentrations of sodium chloride and magnesium chloride.
Thermococcus litoralis (T. litoralis) is a species of Archaea that is found around deep-sea hydrothermal vents as well as shallow submarine thermal springs and oil wells. [2] [3] [4] It is an anaerobic organotroph hyperthermophile that is between 0.5–3.0 μm (20–118 μin) in diameter. [2]
As absurd as it can sound on paper, the truth is that facts are just fun, the more obscure, weird and random, the better. After all, everyone needs a handful of interesting trivia to pull out at ...
Detailed phylogenetic and comparative analyses of genome sequences from members of the class Haloarchaea has led to division of this class into three orders, Halobacteriales, Haloferacales and Natrialbales, which can be reliably distinguished from each other as well as all other archaea/bacteria through molecular signatures known as conserved signature indels (CSIs). [7]
Many hyperthermophilic Archaea require elemental sulfur for growth. Some are anaerobes that use the sulfur instead of oxygen as an electron acceptor during cellular respiration (anaerobic) . Some are lithotrophs that oxidize sulphur to create sulfuric acid as an energy source, thus requiring the microorganism to be adapted to very low pH (i.e ...
BSc meteorologist Janice Davila tells Bored Panda that one of the most unknown facts from her field of expertise is that weather radars are slightly tilted upward in a half-degree (1/2°) angle.
