Description

Associated with activated sludge bulking. In situ and in pure culture, morphology occurs as straight, rod shaped cells forming long filaments, enclosed in clear sheaths with false branching and single rods 1 4 5 3. Metabolism is respiratory and aerobic 6, where a wide range of carbon substrates are utilized for growth.
