Azomonas Azomonas under 100x oil immersion Scientific classification Domain: Bacteria Kingdom: Pseudomonadati Phylum: Pseudomonadota Class: Gammaproteobacteria Order: Pseudomonadales Family: Pseudomonadaceae Genus: Azomonas Winogradsky 1938 Species Azomonas agilis Azomonas insignis Azomonas macrocytogenes

***Azomonas*** species are typically motile, oval to spherical, and secrete large quantities of [capsular slime](/source/Slime_layer). They are distinguished from *[Azotobacter](/source/Azotobacter)* by their inability to form cysts, but like *Azotobacter*, they can biologically fix nitrogen under aerobic conditions ([diazotrophs](/source/Diazotroph)).

[Bacteria](/source/Bacteria) of the genus *Azomonas* are known to form intracellular inclusions of [polyhydroxyalkanoates](/source/Polyhydroxyalkanoates) under certain environmental conditions (e.g. lack of elements such as phosphorus, nitrogen, or oxygen combined with an excessive supply of carbon sources).

## Etymology

The name *Azomonas* derives from:

- [New Latin](/source/Neo-Latin) noun *azotum* [from Fr. noun *azote* (from [Greek](/source/Ancient_Greek_language) prep. ά, *a*, not; [Greek](/source/Ancient_Greek_language) noun ζωή, *zōē*, life; [Greek](/source/Greek_language) noun άζωη, *azōē*, not sustaining life)], nitrogen; New Latin *azo*-, pertaining to nitrogen; [Latin](/source/Latin) [*monas*](/source/-monas) (μονάς), nominally meaning "a unit", but in effect meaning a bacterium; New Latin *Azomonas*, nitrogen monad.[1]

Members of the genus *Azomonas* can be referred to as azomonads (*viz.* [Trivialisation of names](/source/Bacterial_taxonomy#Vernacular_names)).
