Polarography of marine bacteria: A preliminary study
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>109/mL) is manifested in high surface activity and rapid oxygen consumption. In more diluted suspensions of bacteria (N<109/mL) attachment of aggregated cells produces specific current transients that can be distinguished from the background response caused by the collective effect of adhesion of single cells and/or adsorption of their release products. The general pattern of current-time curve sequences has not been described before; it seems to simultaneously reflect a heterogeneous volume distribution of cells and their release products, as well as their interfacial properties.
