The Comamonadaceae are a family of Gram-negative bacteria in the order Burkholderiales.^[1]^[2] The family is phenotypically and metabolically diverse. Cultivated members include aerobic organotrophs, anaerobic denitrifiers and iron-reducing bacteria, hydrogen-oxidizing bacteria, phototrophs, and fermentative bacteria.^[3] Most described members have been isolated from water or soil, although some occur in animal-associated habitats or have been recovered from human clinical samples.^[3]

Taxonomy

The family was established for the acidovorans rRNA complex, with Comamonas as its type genus.^[2]^[1]

Genome-based and 16S rRNA analyses showed that several genera formerly assigned to Comamonadaceae formed a distinct sister lineage. This lineage is now classified as the family Sphaerotilaceae.^[4]^[5] Genera now placed in Sphaerotilaceae include Leptothrix, Sphaerotilus, Caldimonas, Ideonella, and Roseateles.^[5]

Genera

As of August 2026, the following 40 genera have validly published names and are accepted by LPSN as members of Comamonadaceae:^[1]
