Unique archaea bacteria were found by Brett Baker's lab at the University of California Berkely at a mine which has been geologically classified as what?
"massive sulfide ore deposit"
Iron Mountain Mine
Iron Mountain Mine, also known as the Richmond Mine at Iron Mountain, is a mine near Redding in Northern California, US.
 Geologically classified as a "massive sulfide ore deposit", the site was mined for iron, silver, gold, copper, zinc and pyrite intermittently from the 1860s until 1963.
 The mine is the source of extremely acidic mine drainage which also contains large amounts of zinc, copper and cadmium.
 One of America's most toxic waste sites, it has been listed as a federal Superfund site since 1983.
Archaeal Richmond Mine acidophilic nanoorganisms
Archaeal Richmond Mine acidophilic nanoorganisms (ARMAN) were first discovered in an extremely acidic mine located in northern California (Richmond Mine at Iron Mountain) by Brett Baker in Jill Banfield's laboratory at the University of California Berkeley.
 These novel groups of archaea named ARMAN-1, ARMAN-2 ("Candidatus" Micrarchaeum acidiphilum ARMAN-2 ), and ARMAN-3 were missed by previous PCR-based surveys of the mine community because the ARMANs have several mismatches with commonly used PCR primers for 16S rRNA genes.
 Baker "et al." detected them in a later study using shotgun sequencing of the community.
 The three groups were originally thought to represent three unique lineages deeply branched within the Euryarchaeota, a subgroup of the Archaea.
 However, this has been revised, based on more complete archaeal genomic tree, that they belong to a super phylum named DPANN.
 The ARMAN groups now comprise deeply divergent phyla named Micrarchaeota and Parvarchaeota.
 Their 16S rRNA genes differ by as much as 17% between the three groups.
 Prior to their discovery all of the Archaea shown to be associated with Iron Mountain belonged to the order Thermoplasmatales (e.g., "Ferroplasma acidarmanus").
CRM domain
In molecular biology, the CRM domain is an approximately 100-amino acid RNA-binding domain.
 The name CRM (chloroplast RNA splicing and ribosome maturation) has been suggested to reflect the functions established for four characterised members of the family: "Zea mays" (Maize) CRS1, CAF1 and CAF2 proteins and the "Escherichia coli" protein YhbY.
 Proteins containing the CRM domain are found in eubacteria, archaea, and plants.
 The CRM domain is represented as a stand-alone protein in archaea and bacteria, and in single- and multi-domain proteins in plants.
 It has been suggested that prokaryotic CRM proteins existed as ribosome-associated proteins prior to the divergence of archaea and bacteria, and that they were co-opted in the plant lineage as RNA binding modules by incorporation into diverse protein contexts.
 Plant CRM domains are predicted to reside not only in the chloroplast, but also in the mitochondrion and the nucleo/cytoplasmic compartment.
 The diversity of the CRM domain family in plants suggests a diverse set of RNA targets. Haloarchaea
Halobacteria (also Halobacteriacea) are a class of the Euryarchaeota, found in water saturated or nearly saturated with salt.
 Halobacteria are now recognized as archaea, rather than bacteria.
 The name 'halobacteria' was assigned to this group of organisms before the existence of the domain Archaea was realized, and remains valid according to taxonomic rules .
 In a non-taxonomic context, halophilic archaea are referred to as haloarchaea to distinguish them from halophilic bacteria. Aquificae
The Aquificae phylum is a diverse collection of bacteria that live in harsh environmental settings.
 The name 'Aquificae' was given to this phylum based on an early genus identified within this group, "Aquifex" (“water maker”), which is able to produce water by oxidizing hydrogen.
 They have been found in springs, pools, and oceans.
 They are autotrophs, and are the primary carbon fixers in their environments.
 These bacteria are Gram-negative, nonspore-forming rods.
 They are true bacteria (domain Bacteria) as opposed to the other inhabitants of extreme environments, the Archaea. Bacterial cell structure
Bacteria, despite their simplicity, contain a well-developed cell structure which is responsible for some of their unique biological structures and pathogenicity.
 Many structural features are unique to bacteria and are not found among archaea or eukaryotes. Because of the simplicity of bacteria relative to larger organisms and the ease with which they can be manipulated experimentally, the cell structure of bacteria has been well studied, revealing many biochemical principles that have been subsequently applied to other organisms. Crenarchaeota
The Crenarchaeota (Greek for "spring old quality" as specimens were originally isolated from geothermally heated sulfuric springs in Italy) (also known as Crenarchaea or eocytes) are archaea that have been classified as a phylum of the Archaea domain.
 Initially, the Crenarchaeota were thought to be sulfur-dependent extremophiles but recent studies have identified characteristic Crenarchaeota environmental rRNA indicating the organisms may be the most abundant archaea in the marine environment.
 Originally, they were separated from the other archaea based on rRNA sequences; other physiological features, such as lack of histones, have supported this division, although some crenarchaea were found to have histones.
 Until recently all cultured Crenarchaea had been thermophilic or hyperthermophilic organisms, some of which have the ability to grow at up to 113 °C.
 These organisms stain Gram negative and are morphologically diverse having rod, cocci, filamentous and oddly shaped cells. Resistance-nodulation-cell division superfamily
Resistance-nodulation-division (RND) family transporters are a category of bacterial efflux pumps, especially identified in Gram-negative bacteria and located in the cytoplasmic membrane, that actively transport substrates.
 The RND superfamily includes seven families: the heavy metal efflux (HME), the hydrophobe/amphiphile efflux-1 (gram-negative bacteria), the nodulation factor exporter family (NFE), the SecDF protein-secretion accessory protein family, the hydrophobe/amphiphile efflux-2 family, the eukaryotic sterol homeostasis family, and the hydrophobe/amphiphile efflux-3 family.
 These RND systems are involved in maintaining homeostasis of the cell, removal of toxic compounds, and export of virulence determinants.
 They have a broad substrate spectrum and can lead to the diminished activity of unrelated drug classes if over-expressed.
 The first reports of drug resistant bacterial infections were reported in the 1940s after the first mass production of antibiotics.
 Most of the RND superfamily transport systems are made of large polypeptide chains.
 RND proteins exist primarily in gram-negative bacteria but can also be found in gram-positive bacteria, archaea, and eukaryotes. Hydrothermal vent
A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues.
 Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart at spreading centers, ocean basins, and hotspots.
 Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust.
 Common land types include hot springs, fumaroles and geysers. Under the sea, hydrothermal vents may form features called black smokers.
 Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids.
 Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp.
 Active hydrothermal vents are believed to exist on Jupiter's moon Europa, and Saturn's moon Enceladus, and it is speculated that ancient hydrothermal vents once existed on Mars. Lactobacillales
Lactobacillales or lactic acid bacteria (LAB) are an order of Gram-positive, low-GC, acid-tolerant, generally nonsporulating, nonrespiring, either rod- or coccus-shaped bacteria that share common metabolic and physiological characteristics.
 These bacteria, usually found in decomposing plants and milk products, produce lactic acid as the major metabolic end product of carbohydrate fermentation.
 This trait has, throughout history, linked LAB with food fermentations, as acidification inhibits the growth of spoilage agents.
 Proteinaceous bacteriocins are produced by several LAB strains and provide an additional hurdle for spoilage and pathogenic microorganisms.
 Furthermore, lactic acid and other metabolic products contribute to the organoleptic and textural profile of a food item.
 The industrial importance of the LAB is further evidenced by their generally recognized as safe (GRAS) status, due to their ubiquitous appearance in food and their contribution to the healthy microflora of human mucosal surfaces.
 The genera that comprise the LAB are at its core "Lactobacillus", "Leuconostoc", "Pediococcus", "Lactococcus", and "Streptococcus", as well as the more peripheral "Aerococcus", "Carnobacterium", "Enterococcus", "Oenococcus", "Sporolactobacillus", "Tetragenococcus", "Vagococcus", and "Weissella"; these belong to the order Lactobacillales.
