Bacterial dissimilatory MnO2 reduction at extremely haloalkaline conditions

A possibility of dissimilatory MnO2 reduction at extremely high salt and pH was studied in sediments from hypersaline alkaline lakes in Kulunda Steppe (Altai, Russia). Experiments with anaerobic sediment slurries demonstrated a relatively rapid reduction of colloidal MnO2 in the presence of acetate and formate as electron donor at in situ...
