Description

Members of the Candidatus Accumulimonas genus are putative PAOs that appear to have a similar physiology to the Accumulibacter. FISH-MAR analysis indicate that they differ in their ability to assimilate ethanol 1, although more recent genomic studies indicate that some strains of Accumulibacter are also able to utilize this substrate 155. Originally classified to the genus Halomonas they have been reclassified as 'Candidatus Accumulimonas' in the MiDAS taxonomy as they form a novel clade seperate from other members of the genus.
