Comamonadaceae

The Comamonadaceae are a family of Gram-negative bacteria in the order Burkholderiales. 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. 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.
