Composite FISH image of activated sludge. Yellow = "Competibacteraceae"; Blue = Ca. Accumulibacter; Green = other cells. Scale bar = 10 microns. - Source:1
No physiological information is available, although, as a member of the genus "Competibacteraceae" these are thought to compete with the PAO for resources with their proliferation at the theoretical expense of EBPR efficiency 2.
Includes clades CPBS23 and CPBQ07
S23 - CPB586; Q07 - CPB449 3
