• Growth of microaerophilic Fe(II)‐oxidizing bacteria using Fe(II) produced by Fe(III) photoreduction 

      Lueder, UlfORCIDiD; Maisch, MarkusORCIDiD; Jørgensen, Bo Barker; Druschel, Gregory; Schmidt, Caroline; Kappler, AndreasORCIDiD (Geobiology, 2022-01-11)
      Iron(II) (Fe(II)) can be formed by abiotic Fe(III) photoreduction, particularly when Fe(III) is organically complexed. Light‐influenced environments often overlap or even coincide with oxic or microoxic geochemical conditions, ...
    • Microbial biosignatures in ancient deep‐sea hydrothermal sulfides 

      Runge, Eric AlexanderORCIDiD; Mansor, Muammar; Kappler, AndreasORCIDiD; Duda, Jan‐Peter (Geobiology, 2022-12-16)
      Deep‐sea hydrothermal systems provide ideal conditions for prebiotic reactions and ancient metabolic pathways and, therefore, might have played a pivotal role in the emergence of life. To understand this role better, it ...
