Polarography of Marine Bacteria: A Preliminary Study

摘要

We report the first investigations of marine bacteria interactions with the mercury electrode/seawater interface. The effect of marine bacteria on the oxygen electro-reduction process in seawater was studied. The presence of bacteria (N>10~9/mL) is manifested in a high surface activity and rapid oxygen consumption. In more dilu- ted suspensions of bacteria (N<10~9/mL), attachment of aggregated cells produces specific current transients that can be distinguished from the background response caused by the collective effect of ad- hesion of single cells and/or adsorption of their release products.
