Bacteria genera

Merismopedia (from the Greek merismos [division] and the Greek pedion [plain]) is a genus of cyanobacteria found in fresh and salt water. It is ovoid or spherical in shape and arranged in rows and flats, forming rectangular colonies held together by a mucilaginous matrix. Species in this genus divide in only two directions, creating a characteristic grid-like pattern.

Zoogloea, also known as zoöglœa or sewage fungus (though it is not a true fungus), is a genus of gram-negative, aerobic, rod-shaped bacterium that plays a role in wastewater treatment, the degradation of organic pollutants, and environmental bioremediation, from the family of Zoogloeaceae in the Rhodocyclales of the class Betaproteobacteria.

Methylobacterium is a genus of bacteria, also designated as Pink-Pigmented Facultative Methylotrophs (PPFMs). Methylobacterium is commonly found in soil, water, and particularly in association with the phyllosphere, the aerial part of plants. Methylobacterium is characterized by its ability to metabolize one-carbon compounds like methanol released by plant leaves. Methylobacterium plays key roles in nutrient cycling and plant-microbe interactions, often promoting plant growth and resilience through hormone production and stress mitigation. Methylobacterium is a model in biotechnology, already

Gemella is a genus of Gram-positive bacteria that thrive best at high partial pressure of CO2.

Orientia is a genus of bacteria in family Rickettsiaceae. They are obligate intracellular, gram-negative bacteria found in insects and mammals. They are spread through the bites or feces of infected insects.

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. Pantoea bacteria are yellow pigmented, ferment lactose, are motile, and form mucoid colonies. Some species show quorum sensing ability that could drive different gene expression, hence controlling certain physiological activities. 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 ha

Photorhabdus is a genus of bioluminescent, gram-negative bacilli which lives symbiotically within entomopathogenic nematodes, hence the name photo (which means light producing) and rhabdus (rod shape). Photorhabdus is known to be pathogenic to a wide range of insects and has been used as biopesticide in agriculture.

Aerococcus, from Ancient Greek ἀήρ (aḗr), meaning "air", and κόκκος (kókkos), meaning "grain", is a genus of bacterium in the phylum Bacillota (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic Streptococcus on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, b

Desulfotomaculum is a genus of Gram-positive, obligately anaerobic soil bacteria. A type of sulfate-reducing bacteria, Desulfotomaculum can cause food spoilage in poorly processed canned foods. Their presence can be identified by the release of hydrogen sulfide gas with its rotten egg smell when the can is first opened. They are endospore-forming bacteria.

Erysipelothrix is a genus of bacteria containing four described species: Erysipelothrix rhusiopathiae, Erysipelothrix tonsillarum, Erysipelothrix inopinata and Erysipelothrix larvae. Additional species have been proposed based on DNA-DNA hybridization studies. "The hallmark of Erysipelothrix is the presence of a type B cell wall, in which the peptide bridge is formed between amino acids at positions 2 and 4 of adjacent peptide side-chains and not, as in the vast majority of bacteria, between amino acids at positions 3 and 4."

Chryseobacterium is a genus of Gram-negative bacteria. Chryseobacterium species are chemoorganotrophic, rod shape gram-negative bacteria.

The morphology of Weissella species varies from spherical or lenticular cells to irregular rods. Several strains of Weissella cibaria and Weissella confusa have shown probiotic potential. In particular, the cell-free culture supernatant of Weissella confusa shows a number of beneficial characteristics, such as antibacterial potential and anti-inflammatory efficiency. However, several strains of W. confusa are opportunistic bacteria. A

Thiothrix is a genus of filamentous sulfur-oxidizing bacteria, related to the genera Beggiatoa and Thioploca. They are usually Gram-negative (but can be Gram-variable) and rod-shaped (0.7–1.5 μm in width by 1.2–2.5 μm in length). They form ensheathed multicellular filaments that are attached at the base, and form gonidia at their free end. The apical gonidia have gliding motility. Rosettes of the filaments are not always formed but are typical. Sulfur is deposited in invaginations within the cell membrane.

Thermithiobacillus is a genus of nonsporeforming, rod-shaped, Gram-negative bacteria. The name derives from the Latin thermae, for warm baths, and the Classical Greek θείος, theios for sulfur. The type species of this genus was previously assigned to the genus Thiobacillus, but it was reclassified on the basis of 16S rRNA analysis in 2000, creating this genus.

Amycolatopsis is a genus of high GC-content bacteria within the family Pseudonocardiaceae. The genus is known for producing many types of antibiotics, including Epoxyquinomicin, related to Amycolatopsis sulphurea, are a class of weak antibiotic and anti-inflammatory agent. Vancomycin, obtained from Amycolatopsis orientalis, is being used for infections resistant to other antibiotics. Ristocetin, made by Amycolatopsis lurida, was an antibiotic but ceased to apply due to adverse effects of platelet agglutination. Now it is used to assay von Willebrand disease.

Megasphaera is a genus of Bacillota bacteria classified within the class Negativicutes.
