Description

Filamentous organisms with a type 0914 morphotype, which has long been associated with bulking and foaming episodes. Filaments are often arranged in bundles 1. No specific in situ physiological data, although in nutrient removal plants the Chloroflexi seem generally specialized in the aerobic metabolism of saccharides 2.
