Effect of Short Carbonation on Element Mobility in Wood Ash

Abstract During carbonation of wood ash, carbon dioxide reacts with alkali or alkaline earth components in the ash-forming carbonates. The impact of a short carbonation on the mobility of elements in wood ash was investigated. The aim was therefore to apply a sequential extractio...

Geobacter metallireducens —evaluation of its sustainability in nitrate-reducing Fe(II) oxidation under autotrophic conditions

Abstract Bacterial nitrate (NO3−) reducing Fe(II) oxidation is often regarded as an autotrophic process, although its long-term sustainability is rarely demonstrated. Here, we assessed whether Geobacter metallireducens (ATCC 53774) can sustain chemolithoautotrophic nitrate-reduci...
