| Abstract |
A novel extremely thermophilic sulfur-oxidizing bacterium, strain LS12-2(T), was isolated from a deep-sea hydrothermal field at the Yonaguni Knoll IV, Southern Okinawa Trough. Cells of strain LS12-2(T) were motile rods, 1.5-4.0 microm in length and 0.4-0.5 microm in width. Strain LS12-2(T) was an obligate chemolithoautotroph that could utilize elemental sulfur or thiosulfate as an electron donor and nitrate or oxygen as an electron acceptor. Growth was observed at 65-85 degrees C (optimum 70-75 degrees C), pH 5.8-8.3 (optimum pH 6.9-7.5), 1.0-4.0 % (w/v) NaCl (optimum 2.5 %) and 1.0-7.0 % O(2) in the gas phase (optimum 3.0 %). Fatty acids detected were C(16 : 0) (8.0 %), C(18 : 0) (9.0 %), C(18 : 1) (62.5 %) and C(20 : 1) (20.5 %). The genomic DNA G+C content was 51.3 mol%. 16S rRNA gene sequence analysis indicated that strain LS12-2(T) belonged to the genus Hydrogenivirga. Based on physiological and phylogenetic characteristics of the isolate, it is proposed that this strain represents a novel species in the genus Hydrogenivirga, Hydrogenivirga okinawensis sp. nov. The type strain of Hydrogenivirga okinawensis is LS12-2(T) (=JCM 13302(T)=DSM 17378(T)). |
