Composite FISH micrograph of Sulfuritalea-related (Sulf842) in the Aars 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:2Autotroph/Mixotroph
The sole isolate is a facultative autotroph able to oxidize thiosulfate, elemental sulfur and hydrogen as sole energy sources for autotrophic growth and could utilize nitrate as an electron acceptor 4, although attempts to resolve this activity in activated sludge in situ were inconclusive 1. In activated sludge they have a broad substrate uptake profile - assimilating pyruvate, acetate, propionate, amino acids and glucose. They also appear able to utilise nitrite as an electron acceptor indicating a likely role in dentrification. Additional unresolved anaerobic activities are also noted 192 1. Present as small rods distributed throughout the flocs 192.
Sulf842 (should be applied with Sulf431 with different fluorochromes) 2
