摘要A Gram-negative, obligately anaerobic, non-spore-forming, long rod-shaped bacterium strain P2(T) was isolated from the offshore mangrove sediment of the South China Sea. Growth was observed at between 22 and 39 degrees C, with an optimum at 35 degrees C. The pH range for growth was 5.0-8.5, with an optimum around pH 7.0-7.5. Salt tolerance was determined between 0.2 and 3.5% (w/v), optimum at 0.5-1.0%. Catalase and oxidase activities were negative. Strain P2(T) utilized cysteine, lactate, pyruvate, yeast extract or H-2/CO2+acetate as electron donors, and sulfate or sulfite as electron acceptors. Metabolism was strictly fermentative. The main organic fermentation products were propionate, acetate and succinate. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain P2(T) formed a distinct evolutionary lineage within the family Marinilabiliaceae. Strain P2(T) was most closely related to members of the genera Alkaliflexus (92.0% 16S rRNA gene sequence similarity), Marinilabilia (91.7%) and Anaerophaga (89.9%) of the family Marinilabiliaceae. The DNA G+C content of the novel strain was 44.2 +/- 1.0 molok. The dominant fatty acids of strain P2(T) were iso-C-15:0 (33.5 %), anteiso-C-15:0 (18.9%), C-16:0 (5.4%), C-16:0 3-OH (7.7%) and iso-C-17:0 3-OH (13.3%). The respiratory quinone was menaquinone 7 (1000/0 of total quinone) and the major polar lipid was phosphatidylethanolamine. Strain P2(T) was distinguishable from members of phylogenetically related genera by differences in several phenotypic properties. On the basis of phylogenetic, phenotypic and physiological evidence, a novel genus, Mangroviflexus, is proposed to harbour strain P2(T) (=CGMCC 1.5167(T)= DSM 24214(T)) which is described as the type strain of a novel species, Mangroviflexus xiamenensis gen. nov., sp. nov.
