… The variability between the cores was larger than seen in other sediments using the same
method (LP Nielsen, in preparation), and the differences most likely reflected real variations in …

Oxygen consumption in marine sediments is often coupled to the oxidation of sulphide
generated by degradation of organic matter in deeper, oxygen-free layers. Geochemical …

Some bacteria are capable of extracellular electron transfer, thereby enabling them to use
electron acceptors and donors without direct cell contact 1 , 2 , 3 , 4 . Beyond the micrometre …
