Outline of Final Research Achievements

We developed a novel electrical retrieval method for intact and active symbiotic bacteria from gill tissues of deep-sea bivalves Calyptogena okutanii and sponge-associated microorganisms from marine sponges. An indium tin oxide (ITO) optically transparent working electrode was placed on a chamber device with a counter- (Pt) and a reference (Ag/AgCl) electrode. We obtained 31 and 3 phyla of bacteria and archaea from C. okutanii and marine sponges S. insignis and Callyspongia confoederata. The electrically attached microorganisms had intact cell membranes and showed intracellular dehydrogenase activity. Dead microorganisms were not attracted to the electrode when the homogenized tissues were autoclaved before use.
