Confocal micrographs of FISH-stained Nitrotoga-like bacteria in activated sludge samples from WWTPs Bad Zwischenahn. Probes FGall221b (red) and EUB338mix (blue) at high magnification. Nitrotoga appears magenta. Scale bar = 10 microns. - Source:1Autotroph/Mixotroph
Nitrotoga are nitrite oxidizing bacteria that are abundant in some plants. In some cases they are the only detectable NOB present 1. They possess an aerobic chemolithotroph metabolism with oxidation of nitrite to nitrate. Carbon dioxide is used as the sole carbon source 2 1.
