title: Characterization of Marinovum faecis sp. nov., an alphaproteobacterium isolated from marine sediment.
abstract: A Gram-negative, strictly aerobic, chemoheterotrophic, beige-pigmented, ovoid bacterium, designated YP194T, was isolated from marine sediment in the Republic of Korea. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that the novel marine strain belongs to the family Rhodobacteraceae of the class Alphaproteobacteria, with high sequence similarity (98.4%) to Marinovum algicola FF3T. The DNA-DNA relatedness values between strains YP194Tand M. algicola FF3Twere 34.1 ± 2.7%. The DNA G+C content of strain YP194Twas 63.1 mol%. Ubiquinone 10 (Q-10) was the sole respiratory quinone. The predominant cellular fatty acid was C18:1 ω7c (77.6%). Strain YP194Tproduced phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified aminolipid, an unidentified phospholipid and two unidentified lipids as polar lipids. From the combination of genotypic and phenotypic characteristics and the distinct phylogenetic position, the strain is considered to represent a novel species of the genus Marinovum for which the name Marinovum faecis sp. nov. is proposed. The type strain of M. faecis sp. nov. is YP194T(= KCCM 90263T= NBRC 111905T).
