Fig. 3: Composite FISH micrographs of the two most abundant Dechloromonas species in Danish WWTPs.

Specific probes Bet135 (Cy3-label, red) and Dech443 (FLUOS, green) are targeting the Ca. D. phosphoritropha and Ca. D. phosphorivorans, respectively. All bacteria are targeted by EUBmix probe (Cy5-label, blue) and overlap appears in magenta (Ca. D. phosphoritropha - Bet135) or cyan (Ca. D. phosphorivorans - Dech443).
