英文摘要	COMRA program [DY125-15-R-01]; Public Welfare Project of SOA [201005032]; National Infrastructure of Natural Resources for Science and Technology Program of China [NIMR-2011-9, NIMR-2012-9]; A taxonomic study was carried out on strain 22II-S10r2(T), which was isolated from the deep sea sediment of the Atlantic Ocean using oil-degrading enrichment. The bacterium was Gram-negative, oxidase positive and catalase negative, spherical in shape, and motile by polar flagella. Growth was observed at salinities of 0.5-7 % and at temperatures of 10-41 A degrees C. The isolate was capable of aesculin hydrolysis, but unable to reduce nitrate to nitrite or degrade Tween 80 or gelatine. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 22II-S10r2(T) belonged to the family Ectothiorhodospiraceae, with highest sequence similarity to Thioalkalivibrio sulfidiphilus HL-EbGR7(T) (90.9 % similarity). The principal fatty acids were Sum In Feature 8 (C-18:1 omega 7c/omega 6c (29.9 %), C-18:1 omega 9c (13.5 %), C-16:1 omega 5c (12.3 %), C(12:0)3OH (6.8 %), C-18:1 omega 5c (5.7 %) and C-16:0 (5.3 %). The G+C content of the chromosomal DNA was 60.7 mol%. The respiratory quinone was determined to be Q-7 (25 %) and Q-8 (75 %). Phosphatidylethanolamine, phosphatidylglycerol, aminophospholipid, glycolipid, three phospholipids and lipid were present. The strain was aerobic, non-phototrophic and non-chemolithoautotrophic. The combined genotypic and phenotypic data show that strain 22II-S10r2(T) represents a novel species within a novel genus, for which the name Maricoccus atlantica gen. nov. sp. nov. is proposed, with the type strain 22II-S10r2(T) (=CGMCC NO.1.12317(T) = LMG 27155(T) = MCCC 1A09384(T)).
