Description

Members of the genus Petrimonas are fermenters of carbohydrates and some organic acids 2. Growth occurs under anaerobic conditions 2, however both species in the genus are capable of growing in the presence of oxygen 3, with P. mucosa being a facultative anaerobe 3. While peptone and casamino acids are able to support growth, amino acids cannot 3. P. sulfuriphila can use both nitrate and elemental sulphur as electron acceptors reducing these to ammonium and sulfide, respectively 2. In pure culture, cells are rods, that occur singly or in pairs 2. Occasionally, P. mucosa may form filamentous cells 3. No in situ information has been determined for the genus in activated sludge.
