Impact of iron reduction on the metabolism of Clostridium acetobutylicum

Vassily Hatzimanikatis, Rizlan Bernier-Latmani, Karin Lederballe Meibom, Cornelia List, Zhaleh Hosseini

Iron is essential for most living organisms. In addition, its biogeochemical cycling influences important processes in the geosphere (e.g., the mobilization or immobilization of trace elements and contaminants). The reduction of Fe(III) to Fe(II) can be ca ...
