Composite FISH image of CWWC007 filaments (magenta) responding to the CFX998 (red), EUBmix (green) and CFXmix (blue) FISH probes in a full-scale WWTP. Scale bar = 10 microns. - Source:1
Shown to exhibit the Eikelboom 0803 morphotype in situ and may be involved in some bulking episodes. Neither PHA or polyphosphate are stored in situ. No other physiological information is known 1.
