Pantoea is a genus of Gram-negative bacteria of the family Erwiniaceae, recently separated from the genus Enterobacter . This genus includes at least 20 species. [1] Pantoea bacteria are yellow pigmented, [1] ferment lactose, are motile, and form mucoid colonies. [2] Some species show quorum sensing ability that could drive different gene expression, hence controlling certain physiological activities. [3] Levan polysaccharide produced by Pantoea agglomerans ZMR7 was reported to decrease the viability of rhabdomyosarcoma (RD) and breast cancer (MDA) cells compared with untreated cancer cells. In addition, it has high antiparasitic activity against the promastigote of Leishmania tropica . [4]

Enterobacterales is an order of Gram-negative, non-spore forming, facultatively anaerobic, rod-shaped bacteria with the class Gammaproteobacteria. The type genus of this order is Enterobacter.

<i>Thermus</i> Genus of bacteria

Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. According to comparative analysis of 16S rRNA, this is one the most ancient group of bacteria Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins that are exclusively shared by members of this genus.

Pantoea stewartii is a species of plant pathogenic bacteria that causes Stewart's wilt of corn, as well as jackfruit-bronzing disease, bacterial leaf wilt of sugarcane, and leaf blight in rice. P. stewartii is a gram-negative bacterium in the Enterobacterales, a group that also includes Escherichia coli and several other human, animal, and plant pathogens. Most research on this bacterial pathogen to date has been done on strains infecting corn as the other diseases have been identified much more recently. Due to being relatively easy to work with in laboratory research, P. stewartii has been used to study a range of processes in bacterial physiology including quorum sensing, bacterial pigment production, endoglucanase enzymes, and siderophore-mediated iron acquisition.

<i>Cronobacter sakazakii</i> Species of bacterium

Cronobacter sakazakii, which before 2007 was named Enterobacter sakazakii, is an opportunistic Gram-negative, rod-shaped, pathogenic bacterium that can live in very dry places, otherwise known as xerotolerance. C. sakazakii utilizes a number of genes to survive desiccation and this xerotolerance may be strain specific. The majority of C. sakazakii cases are adults but low-birth-weight preterm neonatal and older infants are at the highest risk. The pathogen is a rare cause of invasive infection in infants, with historically high case fatality rates (40–80%).

<i>Cronobacter</i> Genus of bacteria

Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. Several Cronobacter species are desiccation resistant and persistent in dry products such as powdered infant formula. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.

<span class="mw-page-title-main">Levan polysaccharide</span> Chemical compound

Levan is a naturally occurring fructan present in many plants and microorganisms. This polymer is made up of fructose, a monosaccharide sugar, connected by 2,6 beta glycosidic linkages. Levan can have both branched and linear structures of relatively low molecular weight. Branched levan forms a very small, sphere-like structure with basal chains 9 units long. The 2,1 branching allows methyl ethers to form and create a spherical shape. The ends of levan also tend to contain a glucosyl residue. Branched levan tends to be more stable than linear polysaccharides. However, the amount of branching and length of polymerization tends to vary among different species. The shortest levan is 6-kestose, a chain of two fructose molecules and a terminal glucose molecule.

Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Bacillota. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.

<i>Phytobacter</i> Genus of bacteria

Phytobacter is a genus of Gram-negative bacteria emerging from the grouping of isolates previously assigned to various genera of the family Enterobacteriaceae. This genus was first established on the basis of nitrogen fixing isolates from wild rice in China, but also includes a number of isolates obtained during a 2013 multi-state sepsis outbreak in Brazil and, retrospectively, several clinical strains isolated in the 1970s in the United States that are still available in culture collections, which originally were grouped into Brenner's Biotype XII of the Erwinia herbicola-Enterobacter agglomerans-Complex (EEC). Standard biochemical evaluation panels are lacking Phytobacter spp. from their database, thus often leading to misidentifications with other Enterobacterales species, especially Pantoea agglomerans. Clinical isolates of the species have been identified as an important source of extended-spectrum β-lactamase and carbapenem-resistance genes, which are usually mediated by genetic mobile elements. Strong protection of co-infecting sensitive bacteria has also been reported. Bacteria belonging to this genus are not pigmented, chemoorganotrophic and able to fix nitrogen. They are lactose fermenting, cytochrome-oxidase negative and catalase positive. Glucose is fermented with the production of gas. Colonies growing on MacConkey agar (MAC) are circular, convex and smooth with non-entire margins and a usually elevated center. Three species are currently validly included in the genus Phytobacter, which is still included within the Kosakonia clade in the lately reviewed family of Enterobacteriaceae. The incorporation of a fourth species, Phytobacter massiliensis, has recently been proposed via the unification of the genera Metakosakonia and Phytobacter.

Pluralibacter is a genus of Gram negative bacteria from the family of Enterobacteriaceae. The genus consists of two species, P. gergoviae and P. pyrinus. Both species were originally classified in the genus Enterobacter but were reclassified into the novel genus Pluralibacter in 2013.

Pluralibacter pyrinus is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium. P. pyrinus is the causitive agent of brown leaf spot disease of pear trees.

Evansella is a genus of Gram-positive rod-shaped bacteria in the family Bacillaceae within the order Bacillales. The type species for this genus is Evansella cellulosilytica.
