Acidophiles
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 5.0 or below). These organisms can be found in different branches of the tree of life, including Archaea, Bacteria,Becker, A.Types of Bacteria Living in Acidic pH" Retrieved 10 May 2017. and Eukarya. Examples A list of these organisms includes: Archaea :* Sulfolobales, an order in the Thermoproteota branch of Archaea :* Thermoplasmatales, an order in the Euryarchaeota branch of Archaea :* ARMAN, in the Euryarchaeota branch of Archaea :* ''Acidianus brierleyi, A. infernus'', facultatively anaerobic thermoacidophilic archaebacteria :* ''Halarchaeum acidiphilum'', acidophilic member of the Halobacteriacaeae :* ''Metallosphaera sedula'', thermoacidophilic Bacteria :* Acidobacteriota, a phylum of Bacteria :* Acidithiobacillales, an order of Pseudomonadota e.g. ''A. ferrooxidans, A. thiooxidans'' :*''Thiobacillus prosperus, T. acidophilus, T. organovorus, T. cuprinus'' :*''Aceto ...

Archaea
Archaea ( ) is a Domain (biology), domain of organisms. Traditionally, Archaea only included its Prokaryote, prokaryotic members, but this has since been found to be paraphyletic, as eukaryotes are known to have evolved from archaea. Even though the domain Archaea Cladistics, cladistically includes eukaryotes, the term "archaea" (: archaeon , from the Greek "ἀρχαῖον", which means ancient) in English still generally refers specifically to prokaryotic members of Archaea. Archaea were initially Taxonomy (biology), classified as bacteria, receiving the name archaebacteria (, in the Archaebacteria Kingdom (biology), kingdom), but this term has fallen out of use. Archaeal cells have unique properties separating them from Bacteria and Eukaryote, Eukaryota. Archaea are further divided into multiple recognized phylum, phyla. Classification is difficult because most have not been Isolation (microbiology), isolated in a laboratory and have been detected only by their Gene, gene s ...

Acidithiobacillales
The ''Acidithiobacillales'' are an order of bacteria within the class '' Acidithiobacillia'' and comprises the genera ''Acidithiobacillus'' and ''Thermithiobacillus''. Originally, both were included in the genus '' Thiobacillus'', but they are not related to the type species, which belongs to the '' Betaproteobacteria''.Kelly (D.P.) and Wood (A.P.): ''Reclassification of some species of Thiobacillus to the newly designated genera Acidithiobacillus gen. nov., Halothiobacillus gen. nov. and Thermithiobacillus gen. nov.''

Acidobacteriota
Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture. Description Members of this phylum are physiologically diverse, and can be found in a variety of environments including soil, decomposing wood, hot springs, oceans, caves, and metal-contaminated soils. The members of this phylum are particularly abundant in soil habitats representing up to 52% of the total bacterial community. Environmental factors such as pH and nutrients have been seen to drive Acidobacteriota dynamics. Many Acidobacteriota are acidophilic, including the first described member of the phylum, '' Acidobacterium capsulatum''. There is much that is unknown about Acidobacteria both in their form and function. Thus, this is a growing field of microbiology. Some of this uncertainty can be attributed to the difficulty with which these bacteria are grown in the laboratory. There has been recent success ...

Thiobacillus
''Thiobacillus'' is a genus of Gram-negative Betaproteobacteria. ''Thiobacillus thioparus'' is the type species of the genus, and the type strain thereof is the StarkeyT strain, isolated by Robert Starkey in the 1930s from a field at Rutgers University in the United States of America. While over 30 "species" have been named in this genus since it was defined by Martinus Beijerinck in 1904, (the first strain was observed by the biological oceanographer Alexander Nathansohn in 1902 - likely what we would now call '' Halothiobacillus neapolitanus''), most names were never validly or effectively published. The remainder were either reclassified into '' Paracoccus'', '' Starkeya'' (both in the Alphaproteobacteria); ''Sulfuriferula'', '' Annwoodia'', '' Thiomonas'' (in the Betaproteobacteria); '' Halothiobacillus'', '' Guyparkeria'' (in the Gammaproteobacteria), or ''Thermithiobacillus'' or ''Acidithiobacillus'' (in the Acidithiobacillia).

Acetobacter
''Acetobacter'' is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus ''Acetobacter'' is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus ''Acetobacter'' have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures. History of research The acetic fermentation was demonstrated by Louis Pasteur, who discovered the first acetobacter - ''Acetobacter aceti'' - in 1864. In 1998, two strains of ''Acetobacter'' isolated from red wine and cider vinegar were named '' Acetobacter oboediens'' and '' Acetobacter pomorum''. In 2000, ''Acetobacter oboediens'' and '' Acetobacter intermedius'' were transferred to '' Gluconacetobacter'' on the basis of 16S rRNA sequencing. In 2002, '' Acetobacter cerevisiae'' and '' Acetobacter malorum'' were identif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetic Acid
Acetic acid , systematically named ethanoic acid , is an acidic, colourless liquid and organic compound with the chemical formula (also written as , , or ). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Historically, vinegar was produced from the third century BC and was likely the first acid to be produced in large quantities. Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important Reagent, chemical reagent and industrial chemical across various fields, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood Adhesive, glue, and synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the E number, food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is funda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alicyclobacillus
''Alicyclobacillus'' is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures. Overview ''Alicyclobacilli'' are strictly aerobic, acidophilic, mesophilic to thermophilic, soil-dwelling organisms. ''Alicyclobacilli'' are of special interest to the fruit juice canning industry because common pasteurization techniques (92 °C for 10 seconds) do not deactivate the spores; ''Alicyclobacillus'' species can have a D95-value of over 8 minutes (requiring treatment of over 8 minutes at 95 °C to kill 90% of spores). When a product is spoiled by ''Alicyclobacillus'', the juice products develop a disinfectant-like odor and/or flavor (due to guaiacol production), but the bacteria do not cause swelling of the package or discoloration of the product, nor is it pathogenic to humans. ''Alicyclobacilli'' have been implicated in spoilages of pear, orange, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Of Life (biology)
The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's ''On the Origin of Species'' (1859). Tree diagrams originated in the Middle Ages, medieval era to represent family tree, genealogical relationships. Phylogenetic tree diagrams in the evolutionary sense date back to the mid-nineteenth century. The term phylogeny for the evolutionary relationships of species through time was coined by Ernst Haeckel, who went further than Charles Darwin, Darwin in proposing Phylogenetics, phylogenic histories of life. In contemporary usage, ''tree of life'' refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth. Two public databases for the tree of life are ''TimeTree'', for phylogeny and divergence times, and the ''Ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucor Racemosus
''Mucor racemosus'' is a rapidly growing, weedy mould belonging to the division Mucoromycota. It is one of the earliest fungi to be grown in pure culture and was first isolated in 1886. It has a worldwide distribution and colonizes many habitats such as vegetational products, soil and houses. The fungus is mostly known for its ability to exhibit both filamentous and yeast-like morphologies, often referred to as dimorphism. Stark differences are seen in both forms and conditions of the environment heavily affect the phases of the ''M. racemosus''. Like many fungi, it also reproduces both sexually and asexually. The dimorphic capacity of this species has been proposed as an important factor in its pathogenicity and has enhanced the industrial importance. This species is considered an opportunistic pathogen, generally limited to immunocompromised individuals. It has also been associated with allergy and inflammations of facial sinuses. Its association with allergy has made it a comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanidioschyzon
''Cyanidioschyzon merolae'' is a small (2μm), club-shaped, unicellular Ploidy, haploid Rhodophyta, red alga adapted to high sulfur acidic hot spring environments (pH 1.5, 45 °C). The cellular architecture of ''C. merolae'' is extremely simple, containing only a single chloroplast and a single mitochondrion and lacking a vacuole and cell wall. In addition, the cellular and organelle divisions can be synchronized. For these reasons, ''C. merolae'' is considered an excellent model system for study of cellular and organelle division processes, as well as biochemistry and structural biology. The organism's genome was the first full algal genome to be sequencing, sequenced in 2004; its plastid was sequenced in 2000 and 2003, and its mitochondrion in 1998. The organism has been considered the simplest of eukaryotic cells for its minimalist cellular organization. Isolation and growth in culture Originally isolated by De Luca in 1978 from the solfatane fumaroles of Campi Flegrei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
