| Outline of Final Research Achievements |
To understand the ecological and evolutional functions of extracellular outer membrane vesicles in deep-sea hydrothermal environments, we analyzed the DNA content of membrane vesicles released by chemolithoautotrophic microorganisms which belong to the class Epsilonproteobacteria. We choose the strain which produces the most abundant vesicles as the representative strain from Epsilonproteobacterial isolates, and sequenced DNA purified from the membrane vesicles. We revealed that the strain released DNA within vesicles, which encoded broadly distributed regions of the genome. This suggests that membrane vesicles could have important implications for mechanisms of horizontal gene transfer in deep-sea hydrothermal ecosystems.
