Myxococcaceae
Myxococcaceae is a family of gram-negative, rod-shaped bacteria. The family Myxococcaceae is encompassed within the myxobacteria ("slime bacteria"). The family is ubiquitously found in soils, marine, and freshwater environments. Production of compounds with medical uses by Myxococcaceae makes them useful in human health fields. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) Morphology and Behavior Cells can be motile with gliding and swarming behavior. The vegetative cell shape in the Myxococcaceae family is long rods, which vary in size between members. The most common fruiting body morphs are soft hump and knob shaped with possible colors of yellow, peach, white, or orange depending on species. Myxococcaceae are spore producing bacteria and are delineated by their spore shape. The myxospores are oval to round and are optically refractive. Quoru ...

Myxobacteria
The myxobacteria ("slime bacteria") are a group of bacteria that predominantly live in the soil and feed on insoluble organic substances. The myxobacteria have very large genomes relative to other bacteria, e.g. 9–10 million nucleotides except for '' Anaeromyxobacter'' and ''Vulgatibacter''. One species of myxobacteria, ''Minicystis rosea'', has the largest known bacterial genome with over 16 million nucleotides. The second largest is another myxobacteria ''Sorangium cellulosum''. Myxobacteria can move by gliding. They typically travel in ''swarms'' (also known as ''wolf packs''), containing many cells kept together by intercellular molecular signals. Individuals benefit from aggregation as it allows accumulation of the extracellular enzymes that are used to digest food; this in turn increases feeding efficiency. Myxobacteria produce a number of biomedically and industrially useful chemicals, such as antibiotics, and export those chemicals outside the cell. Myxobacteria are u ...

Myxococcus
''Myxococcus'' is a genus of bacteria in the family Myxococcaceae. Myxococci are Gram-negative, spore-forming, chemoorganotrophic, obligate aerobes. They are elongated rods with rounded or tapered ends, and they are nonflagellated. The cells move by gliding and can predate other bacteria. The genus has been isolated from soil. At least eleven species had been identified with confidence by late 2020 and each had been characterised to some extent. As well as using traditional biochemical tests, strains of some species had been compared using whole genome sequences. This approach has provided evidence that the genus, like most bacterial genera, has a core set of genes found in all members of the genus, along with others that are confined to particular species. The identity of ''Myxococcus'' species therefore continues to change. An example where taxonomy may be changed is that comparisons of genome sequences and biochemical tests indicated that '' M. xanthus'' and ''M. virescens'' ...

Stigmatella (bacterium)
''Stigmatella'' is a bacterium genus in the phylum Myxococcota. Etymology The name ''Stigmatella'' derives from:Latin neuter gender noun ''stigma'' -''atis'', brand, mark; Latin feminine gender dim. ending -''ella''; New Latin feminine gender noun ''Stigmatella'', small dark spot. Species The genus contains three species (including basonyms and synonyms), namely * '' S. aurantiaca'' Berkeley and Curtis 1875 ((Type species of the genus).; New Latin feminine gender adjective ''aurantiaca'', orange colored.) * '' S. erecta'' (Schroeter 1886) McCurdy 1971 (Latin feminine gender participle adjective ''erecta'' (from Latin v.

List Of Bacterial Orders
This article lists the orders of the Bacteria. The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI) and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project. Phylogeny National Center for Biotechnology Information (NCBI) taxonomy was initially used to decorate the genome tree via tax2tree. The 16S rRNA-based Greengenes taxonomy is used to supplement the taxonomy particularly in regions of the tree with no cultured representatives. List of Prokaryotic names with Standing in Nomenclature (LPSN) is used as the primary taxonomic authority for establishing naming priorities. Taxonomic ranks are normalised using phylorank and the taxonomy manually curated to remove polyphyletic groups. Cladogram was taken from GTDB release 07-RS207 (8th April 2022).

Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Quorum Sensing
In biology, quorum sensing or quorum signalling (QS) is the ability to detect and respond to cell population density by gene regulation. As one example, QS enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In a similar fashion, some social insects use quorum sensing to determine where to nest. Quorum sensing in pathogenic bacteria activates host immune signaling and prolongs host survival, by limiting the bacterial intake of nutrients, such as tryptophan, which further is converted to serotonin. As such, quorum sensing allows a Commensalism, commensal interaction between host and pathogenic bacteria. Quorum sensing may also be useful for cancer cell communications. In addition to its function in biological systems, quorum sensing has several useful applications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystobacter Miniatus
''Cystobacter'' is a genus in the phylum Myxococcota (Bacteria).

Genome Taxonomy Database
The Genome Taxonomy Database (GTDB) is an online database that maintains information on a proposed nomenclature of prokaryotes, following a phylogenomic approach based on a set of conserved single-copy proteins. In addition to breaking up paraphyletic groups, this method also reassigns taxonomic ranks algorithmically, creating new names in both cases. Information for archaea was added in 2020, along with a species classification based on average nucleotide identity. Each update incorporates new genomes as well as human adjustments to the taxonomy. An open-source tool called GTDB-Tk is available to classify draft genomes into the GTDB hierarchy. The GTDB system, via GTDB-Tk, has been used to catalogue not-yet-named bacteria in the human gut microbiome and other metagenomic sources. The GTDB is incorporated into the ''Bergey's Manual of Systematics of Archaea and Bacteria'' in 2019 as its phylogenomic resource. See also * PhyloCode * National Center for Biotechnology Informa ...

The All-Species Living Tree Project
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB Project, ARB, SILVA rRNA database project, and List of Prokaryotic names with Standing in Nomenclature, LPSN, with the aim of assembling a database of 16S ribosomal RNA, 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S ribosomal RNA, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
