From: Anaerobic reduction of europium by a Clostridium strain as a strategy for rare earth biorecovery
Electron microscopy micrographs of Clostridium sp. 2611. Bars indicate the scale as micrometres and red shapes indicates association of Eu. (a) Scanning electron microscope of Clostridium sp. control cells, and (b) Eu3+ exposed cells. Europium damaged cell wall. (c,d) Transmission electron microscopy micrographs of Eu3+ bioaccumulation by Clostridium sp. (e,f), red circles indicate the location of Eu (Shown as electron-dense granules). Overlaid EDX spectra.
