Composite FISH micrographs of Dechloromonas-related (Dech443) in a full-scale WWTP. Target cells in FISH micrograph overlays appear magenta [target probe (CY3 = red) + EUBmix (CY5 = blue)] and non-target blue (EUBmix only). Scale bar represents 20 microns. - Source:1

Description

Rods/coccobacilli, sometimes forming microcolonies 1 2. Able to assimilate VFAs under anoxic conditons and utilise nitrite as electron acceptor indicating a role in dentrification. Some appear to possess the PAO phenotype 1 2, while members of the genus have also been reported as putative competitors of the PAO in EBPR 5. A recent isolate of the genus from a full-scale nutrient removal system, was shown to accumulate relatively high levels of polyphosphate in axenic culture 11. Suggested to be involved in perchlorate reduction 6.
