英文摘要	A taxonomic study was carried out on strain P1(T), which was isolated from mangrove sediment samples collected from Qinglan Port (Hainan, China). Cells were curved rods, that were motile, with a single polar flagellum. The strain was non-spore-forming with a cell size of 0.6x1.5-2.2 mu m. Catalase and oxidase activities were not detected. Growth was observed in the temperature range 22-44 degrees C (optimum, 35-40 degrees C) and pH range 5.5-8.5 (optimum, pH 7.0). NaCl was required for growth and tolerated at up to 3.5% (w/v) (optimum, 0.5%). Strain P1(T) utilized hydrogen, succinate, L-malate, citrate, oxalate, DL-lactate, pyruvate, or cysteine as electron donors, and sulfate or sulfite as electron acceptors. Fermentation products from pyruvate were acetate, H-2 and CO2. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain P1(T) formed a distinct evolutionary lineage within the family Desulfovibrionaceae. Strain P1(T) was most closely related to members of the genera Desulfovibrio (92.0-94.3% 16S rRNA gene sequence similarity), Desulfocurvus (91.1%), Bilophila (87.9%) and Lawsonia (86.0 %) of the family Desulfovibrionaceae. The DNA G+C content of strain P1(T) was 64.5 mol% and the major cellular fatty acids were iso-C-15:0 (18.8%), anteiso-C-15:0 (5.0 %), C-16:0 (14.2%) and iso-C-17:1 omega 9c (24.4%). The predominant menaquinone was MK-7 (97%). Major polar lipids were phosphatidylcholine, phosphatidylethanolamine and phosphatidylglycerol. Strain P1(T) was distinguishable from members of phylogenetically related genera by differences in several phenotypic properties. On the basis of the phenotypic and phylogenetic data, strain P1(T) represents a novel species of a new genus, for which the name Desulfobaculum xiamenensis gen. nov., sp. nov. is proposed. The type strain of Desulfobaculum xiamenensis is P1(T) (=CGMCC 1.5166(T)=DSM 24233(T)).
