| Research Abstract |
The author developed an electrical modulation method for attachment and detachment of microorganisms. When we applied this method to separate microorganisms from deep-sea sediment, bacteria belonging to 19 phyla and 23 classes were collected without undesirable high molecular-weight contaminants such humic acids. At the phylum level 95% and at the class level 87% of the phylotypes among electrically retrieved bacteria were common to the gene clones from the direct sediment DNA extraction.
