Formatted Abstract/Summary
Glycogen-accumulating organisms (GAOs) were present in six full-scale plants investigated and in all but one made a significant contribution to the amount of volatile fatty acid (VFA) taken up anaerobically. While most plants surveyed contain GAOs, it was demonstrated that it is possible for a full-scale plant to operate with an insignificant GAO population. “Candidatus Accumulibacter phosphatis” were the significant polyphosphate-accumulating organisms (PAOs) in all plants surveyed. “Candidatus Competibacter phosphatis” were found in all plants along with other possible GAOs that were observed but not identified. A significant GAO population will increase the carbon requirements by removing VFA that could otherwise have been used by PAOs. Process efficient use of VFA.
