Description

Tetrad forming organisms orignally believed to be GAOs. However pure cultures were shown to be unable to assimilate carbon under anaerobic conditions 2. Aerobic heterotrophs, which have a high capacity for PHA storage 2. No information on their in situ physiology in activated sludge is availabe.
