| Research Abstract |
The mechanism of hydrogen interspecies transfer which enables to dechlorinate trichloroethene (TCE) effectively was characterized. Methane production was observed during TCE-dechlorination in the non-effective dechlorinating culture, while methane was produced rapidly after TCE-dechlorination in the effective dechlorinating culture. Molecular techniques revealed that aceticlastic methanogens competed with Dechlorinator, on the other hand, hydrogenotrophic methanogens did not. These results suggested that the activity of anaerobic acetate oxidizing bacteria play a key role for efficient dechlorination. We succeeded to isolate anaerobic acetate oxidizing bacteria, closely related to Moraxella osloensis.
