Description

Glycogen accumulating organsims (GAO) thought to compete with the PAO for resources with their proliferation at the theoretical expense of EBPR efficiency 6. Thought to specialize in short chain fatty acids which are stored as PHA under anaerobic conditions 7 8. Filamentous forms are also implicated in bulking 9.

Distribution plant/process configuration

Nutrient removal systems treating both domestic and municiple wastes. Relative higher abundance in EBPR plants 10. Their proliferation has been suggested to be due to excess substrate availability, due to a high COD:P ration or EBPR failure 11.

Diversity

Defluviicoccus-related clusters I, II, III & IV. Clusters I, II and IV exhibit a tetrad forming organism (TFO) morphology 6 5 9 10.

FISH probes

Cluster I = DF776 6; Cluster II = DF988 + DF1020 5; Cluster III = DF198 9; Cluster IV = DF180b 10
