Isolation of '<i>Candidatus</i> Ferrigenium straubiae' - a microaerophilic Fe(II)-oxidizing bacterium and nitrate-reducing Fe(II)-oxidizer within the community of culture KS.

ABSTRACT: 'Candidatus Ferrigenium straubiae' strain KS (KCTC 25982, DSM 118991) is a neutrophilic, Fe(II)-oxidizing bacterium representing up to 98% of the community in culture KS, the most extensively studied mixed culture known for autotrophic nitrate-reducing Fe(II) oxidation. The phylogeny and genome of this bacterium were previously analysed and identified as 'Candidatus Ferrigenium straubiae'. In this study, we report the first-time successful isolation of 'Candidatus Ferrigenium straubiae' strain KS and its experimental physiological characterization. The bacterium was identified as a non-stalk-forming, rod-shaped and non-halophilic strain with a Gram-negative classification. We characterized its physiology when grown in agarose-stabilized Fe(II)-O₂ gradient tu
