Beskrivelse

Defluviicoccus er glykogen akkumulerende organismer (GAO) og foreslået som konkurrenter til biologisk fosforfjernelse da de lever af samme substrat som BioP-bakterierne (PAO) formentlig uden at akkumulere polyfosfat. De trådformende typer er impliceret i dårlig bundfældning.

Diversitet

Defluviicoccus deles op i fire clusters. Clusters I, II og IV har tetrademorfologi. Cluster III er trådformende af 'Nostocoida limicola'-typen.

Fysiologi

Glykogen akkumulerende bakterier (GAO). Er formentlig specialiseret i udnyttelse af kortkædede fedtsyrer som optages og oplagres under anaerobe forhold. Vokser under oxiske forhold.

Udbredelse og anlægs/proces-forhold

Findes i anlæg, der behandler byspildevand, men også i anlæg, der modtager husholdningsaffald. De har en relativ højere udbredelse i anlæg med biologisk fosforfjernelse. De kan ved varmere klimaer påvirke den biologiske fosforfjerelse negativt.
