Beskrivelse

BioP-bakterier (PAO). Aerob. Nogle typer kan denitrificere. De optager kulstof under anaerobe forhold og oplagrer polyfosfat under aerobe forhold. Er de primære BioP-bakterier i renseanlæg med fede syrer i spildevandet.

Diversitet

Gruppe I og II består af flere forskellige undergrupper. De denitrificerende Accumulibacter hører formentlig kun til gruppe I.

Fysiologi

BioP-bakterier (PAO). Er specialiseret i at optage og lagre kortkædede fedtsyrer ved hydrolyse under anaerobe forhold, hvor deres polyfosfatlager forbruges som energikilde. Under aerobe forhold optages fosfor og lagres i cellerne som polyfosfat.

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.
