摘要:	An aerobic, Mn(II)-oxidizing and Gram-negative bacterium, strain 8047T, was isolated from a deep sea hydrothermal vent plume in the Southwest Indian Ocean. The strain was rod-shaped and motile with a terminal flagellum, and formed yellowish colonies. It produced catalase and oxidase, hydrolyzed gelatin and reduced nitrate. 16S rRNA gene sequence analysis showed that strain 8047T belonged to the order Rhizobiales of Alpha-proteobacteria, and was phylogentically related most closely to the genus Fulvimarina, sharing 94.4% sequence identity with the latter. The taxonomic affiliation of strain 8047T is supported by phylogenetic analysis of four additional housekeeping genes, i.e., gyrB, recA, rpoC and rpoB. The predominant respiratory lipoquinone of strain 8047T was Q10, the major fatty acid was C18:1omega7c, and the DNA G+C content was 61.7 mol%. On the basis of phenotypic and genotypic characteristics obtained in this study, strain 8047T (=CGMCC1.10972 T =JCM 18890T) represents a novel species within the genus Fulvimarina, for which the name Fulvimarina manganoxydans sp. nov. is proposed.
