| sulfurihydrogenibium azorense, sp. nov., a thermophilic hydrogen-oxidizing microaerophile from terrestrial hot springs in the azores. | five hydrogen-oxidizing, thermophilic, strictly chemolithoautotrophic, microaerophilic strains, with similar (99-100%) 16s rrna gene sequences were isolated from terrestrial hot springs at furnas, são miguel island, azores, portugal. the strain, designated az-fu1t, was characterized. the motile, 0.9-2.0 microm rods were gram-negative and non-sporulating. the temperature growth range was from 50 to 73 degrees c (optimum at 68 degrees c). the strains grew fastest in 0.1% (w/v) nacl and at ph 6, al ... | 2004 | 14742456 |
