Zoogloeaceae
Zoogloeaceae is a Family (biology), family of bacteria in the order Rhodocyclales. In 2017, Boden et al. proposed the creation of Zoogloeaceae and Azonexaceae to harmonize the taxonomy with 16S ribosomal RNA, 16S rRNA gene-based Phylogenetic tree, phylogeny as well as physiology. The type genus, from whence the name is derived, is ''Zoogloea.'' In 2021, Huang et al. added four new genera to the family. At present, the family comprises 13 genera, with 44 sequenced genomes and 73 representative 16S rRNA gene sequences. Zoogloeaceae is characterized by a rod shape and one or more flagella. Species are metabolically diverse and are implicated in nitrogen cycling. References Bacteria families Zoogloeaceae, Rhodocyclales Taxa described in 2017 {{improve categories, date=March 2025 ...

Azoarcus
''Azoarcus'' is a genus of nitrogen-fixing bacteria. Species in this genus are usually found in contaminated water, as they are involved in the degradation of some contaminants, commonly inhabiting soil. These bacteria have also been found growing in the endophytic compartment (inside the plant between the living cells) of some rice species and other grasses. The genus is within the family ''Zoogloeaceae'' in the ''Rhodocyclales'' of the ''Betaproteobacteria''. Many studies reported this genus about its potential extracellular electron uptake metabolism and has been found in the cathodic part of many microbial fuel cells, notably in nitrate and oxygen reducing bio-cathodes biofilm A biofilm is a Syntrophy, syntrophic Microbial consortium, community of microorganisms in which cell (biology), cells cell adhesion, stick to each other and often also to a surface.

Rhodocyclales
The Rhodocyclales are an order of the class Betaproteobacteria in the phylum Pseudomonadota ("Proteobacteria").Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . Following a major reclassification of the class in 2017, the previously monofamilial order was split into three families: * Rhodocyclaceae ( type family) contains the genera '' Rhodocyclus'' (type genus), '' Azospira'' and '' Propionivibrio''. Cells are curved rods, rings or spirillae. Dominant respiratory quinones are Vitamin K2, menaquinone-8, ubiquinone-8 and rhodoquinone-8. G+C fractions are 61.6 - 65.3 mol%. * Azonexaceae contains the genera '' Azonexus'' (type genus), '' Dechloromonas'', '' Ferribacterium'' and '' Quatrionicoccus''. Cells are curved rods or cocci. Dominant respiratory quinone is ubiquin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoogloea
''Zoogloea'', also known as zoöglœa, 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 ''Betaproteobacteria'' are a class of Gram-negative bacteria, and one of the six classes of the phylum '' Pseudomonadota'' (synonym Proteobacteria). Metabolism The ''Betaproteobacteria'' comprise over 75 genera and 400 species. Together, they .... Taxonomy and classification The genus ''Zoogloea'' was first described in the 19th century but has undergone substantial taxonomic revisions. A pivotal study by Shin, Hiraishi, and Sugiyama utilized 16S rRNA gene sequencing to update the classification of the genus,Shin, Y. K., Hiraishi, A., & Sugiyama, J. (1993).

Most species of this genus are motile by flagella and are mostly rod-shaped.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005).
