| nitratiruptor tergarcus gen. nov., sp. nov. and nitratifractor salsuginis gen. nov., sp. nov., nitrate-reducing chemolithoautotrophs of the epsilon-proteobacteria isolated from a deep-sea hydrothermal system in the mid-okinawa trough. | two novel denitrifying bacteria, designated strains mi55-1(t) and e9i37-1(t), were isolated from deep-sea hydrothermal vent chimney structures at the iheya north hydrothermal field in the mid-okinawa trough, japan. both isolates were strict chemolithoautotrophs growing by respiratory nitrate reduction with h(2), forming n(2) as a metabolic product. oxygen (at low concentrations) could serve as an alternative electron acceptor for growth of the isolates. growth of strain mi55-1(t) was observed at ... | 2005 | 15774687 |
