Description

The organism is suggested to be a putative GAO as acetate and glucose are assimilated under anaerobic conditions in the absence of excess polyphosphate storage in situ 2 and glycogen is stored under aerobic or anaerobic conditions in pure culture 1. Further studies are required to elucidate its physiology and role in EBPR. The sole isolate of the genus, Micropruina glycogenica, was isolated from a lab-scale EBPR system. Cells are cocci, occurring in pairs, packets or clusters 1.
