Filamentous organisms with a type 0914 morphotype, which has long been associated with bulking and foaming episodes. Filaments are often arranged in bundles 1. In nutrient removal plants the Chloroflexi seem generally specialized in the aerobic metabolism of saccharides 2.
Relatively more abundant in EBPR plants 1.
