Dehalococcoidetes

	Dehalococcoidetes ''Dehalococcoidia'' is a class of Chloroflexota, a phylum of Bacteria. It is also known as the DHC group. The name ''Dehalococcoidetes'' is a placeholder name given by Hugenholtz and Stackebrandt, 2004, after ''Dehalococcoides ethenogenes'', a partially described species in 1997, whereas the first species fully described belonging to this class was '' Dehalogenimonas lykanthroporepellens'' by Moe et al. 2009, but no emendations to the name were made. Characteristics Both species, ''Dehalococcoides ethenogenes'' and ''Dehalogenimonas lykanthroporepellens'' are irregular coccus (coccoid) bacteria capable of dehalogenating polychlorinated aliphatic alkanes and alkenes, such as tetrachloroethene, trichloropropane, trichloroethane, dichloropropane, and dichloroethane. One of the features of the members of the phylum Chloroflexota is the unusual cell wall structure, which is monoderm but with great variation in presence or structure of the peptidoglycan resulting in many membe ...

	Chloroflexota The Chloroflexota are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ( green non-sulfur bacteria); and anaerobic halorespirers, which uses halogenated organics (such as the toxic chlorinated ethenes and polychlorinated biphenyls) as electron acceptors. The members of the phylum ''Chloroflexota'' are monoderms (that is, have one cell membrane with no outer membrane), but they stain mostly gram-negative. Many well-studied phyla of bacteria are diderms and stain gram-negative, whereas well-known monoderms that stain Gram-positive include ''Firmicutes'' (or ''Bacillota'') ( low G+C gram-positives) and '' Actinomycetota'' (high-G+C gram-positives). History The taxon name was created in the 2001 edition of Volume 1 of Bergey's Manual of Systematic Bacteriology and is the Latin plural of the n ...

	Dehalogenimonas Lykanthroporepellens ''Dehalogenimonas lykanthroporepellens'' is an anaerobic, Gram-negative bacteria in the phylum Chloroflexota isolated from a Superfund site in Baton Rouge, Louisiana. It is useful in bioremediation for its ability to reductively dehalogenate chlorinated alkanes. Discovery and description '' Dehalogenimonas lykanthroporepellens'' cells are Gram-negative, non-motile, irregular cocci that are 0.3–0.6 μm in diameter. There is no evidence of pathogenicity. They are mesophiles that can grow in a temperature range of 20–34 °C with their optimum temperature range being 28–34 °C. They grow best in pH 7-7.5 (pH range 6–8, although it was isolated from groundwater of pH 5.1). Growth has been observed in salt concentrations from 0.1–2% NaCl with optimum growth at ≤1%. GC-content reported in characterization of ''D. lykanthroporellens'' is 53.8% as determined by HPLC; however, as determined by genomic analysis, the GC-content is 55.04%.

	Bioaugmentation Biological augmentation is the addition of archaea or bacterial cultures required to speed up the rate of degradation of a contaminant. Organisms that originate from contaminated areas may already be able to break down waste, but perhaps inefficiently and slowly. Bioaugmentation is a type of bioremediation in which it requires studying the indigenous varieties present in the location to determine if biostimulation is possible. After discovering the indigenous bacteria found in the location, if the indigenous bacteria can metabolize the contaminants, more of the indigenous bacterial cultures will be implemented into the location to boost the degradation of the contaminants. Bioaugmentation is the introduction of more archaea or bacterial cultures to enhance the contaminant degradation whereas biostimulation is the addition of nutritional supplements for the indigenous bacteria to promote the bacterial metabolism. If the indigenous variety do not have the metabolic capability to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Dehalogenimonas ''Dehalogenimonas'' is a genus in the phylum Chloroflexota (Bacteria). Members of the genus ''Dehalogenimonas'' can be referred to as dehalogenimonads (''viz.'' Trivialisation of names). Etymology The name ''Dehalogenimonas'' derives from:Latin prep. ''de'', away, off; Neo-Latin noun ''halogenum'', halogen; Latin feminine gender noun '' monas (μονάς)'', unit, monad; Neo-Latin feminine gender noun ''Dehalogenimonas'', dehalogenating monad, reflecting the ability of these bacteria to dehalogenate chlorinated alkanes. The type species of the genus is '' D. lykanthroporepellens'' (Moe ''et al''. 2009). The species epithet derives from the Greek noun ''lykanthropos (λυκάνθρωπος)'', werewolf; Latin participle adjective ''repellens'', repelling; Neo-Latin participle adjective ''lykanthroporepellens'', repelling `werewolves, because compounds exhibiting a pungent garlic aroma are produced when these organisms grow in the presence of 1,2,3-trichloropropane as an electron ...

	Peptidoglycan Peptidoglycan or murein is a unique large macromolecule, a polysaccharide, consisting of sugars and amino acids that forms a mesh-like layer (sacculus) that surrounds the bacterial cytoplasmic membrane. The sugar component consists of alternating residues of β-(1,4) linked N-Acetylglucosamine, ''N''-acetylglucosamine (NAG) and N-Acetylmuramic acid, ''N''-acetylmuramic acid (NAM). Attached to the ''N''-acetylmuramic acid is an oligopeptide chain made of three to five amino acids. The peptide chain can be cross-linked to the peptide chain of another strand forming the 3D mesh-like layer. Peptidoglycan serves a structural role in the bacterial cell wall, giving structural strength, as well as counteracting the osmotic pressure of the cytoplasm. This repetitive linking results in a dense peptidoglycan layer which is critical for maintaining cell form and withstanding high osmotic pressures, and it is regularly replaced by peptidoglycan production. Peptidoglycan hydrolysis and synthesis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
