TEM analysis of cell/Fe(III) oxide aggregates produced by a chemolithoautotrophic Fe(II)-oxidizing, nitrate-reducing enrichment culture


EMSL Project ID
34318

Abstract

We request high-resolution TEM analysis of Fe(III) oxides produced during anaerobic oxidation of soluble Fe(II) (ferrous chloride) by a chemolithoautotrophic Fe(II)-oxidizing, nitrate-reducing enrichment culture. The goal of the analysis is to determine whether or not there is evidence for encrustation of the cells by the biogenic Fe(III) oxides, and also to assess whether the size and morphology of the oxides varies as a function of the aqueous-phase conditions under which Fe(II) oxidation takes place.
