Description

Aerobic, heterotrophs 2 that have been associated with the bulking in activated sludge WWTPs 3. Cells are straight rods, which may occur singly, in pairs or chains 2. Filamentous colonies may form under certain conditions 2. Oxidation of manganese is typical for bacteria belonging to the genus 2. Nothing is known about the physiology of the genus in situ.
