The effects of acetate concentrations on competition between microbial populations in enhanced biological phosphorus removal from wastewater
… the glycogen accumulating organisms (GAOs). Because research EBPR systems have been primarily sequencing batch reactors (SBRs), which include rapid feed addition and relatively high substrate concentrations, while full scale systems often include complete mix reactors, which yield …

The Effects Of Ph On Enhanced Biological Phosphorus Removal (ebpr) With Propionic Acid As The Dominant Volatile Fatty Acid (vfa)
… faster than glycogen-accumulating organisms (GAOs). They explained this observation by comparing the growth rate of phosphorus-accumulating organisms (PAOs) and glycogen-accumulating organisms (GAOs) and found that pH has little effect on PAOs growth rate but adversely affects GAOs growth rate …

Bioplastics from C1 Gases - Substitute Sustainable Products for Polymer Coated Steel
… proposed to use glycogen-accumulating organisms (GAOs), which are bacteria obtained from wastewater treatment plants, to produce mixes of biopolymers called polyhydroxyalkanoates (PHA). With acetate as the sole carbon source and by varying several culture conditions (substrate concentration, …

METABOLIC SHIFT AND NICHE DIFFERENTIATION DURING DENITRIFYING PHOSPHORUS REMOVAL IN A TROPICAL CLIMATE
… terminal electron acceptors inhibited growth of GAOs. Finally, the denitrification abilities and N2O reduction capability of Accumulibacter was characterized and contrasted with Competibacter and Defluviicoccus. A clear preference for nitrite utilization was observed for Accumulibacter while …

Evaluation of Glycerol and Waste Alcohol as Supplemental Carbon Sources for Denitrification
… the presence of glycogen-accumulating organisms (GAOs) could be responsible for this intracellular storage of glycerol resulting in partial denitrification and accumulation of nitrite. The methanol and waste alcohol reactors also performed similarly to each other and neither of these reactors …

The Effects of Temperatures on System Performance and Bacterial Community Structure in a Biological Phosphorus Removal System
… between PAO and glycogen accumulating organisms (GAOs) at 20°C and cold temperature (5°C) nearly eliminates this competition in favor of the PAOs. A series of batch test experiments revealed that despite similar acetate utilization by the sludges grown at the two temperatures nearly 30% less PHA …
