Description

In axenic culture, members of the genus show swarming motility and produce fruiting bodies. Simple sugars do not appear to be utilised, with the organisms relying on peptones or proteins for growth 2. Bacterial groups within the order Myxococcales, are suggested to degrade active and/or dead cells in activated sludge (micropredators) 1. The in situ physiology of the genus in activated sludge has not been determined.
