title: Mameliella atlantica sp. nov., a marine bacterium of the Roseobacter clade isolated from deep-sea sediment of the South Atlantic Ocean.
abstract: A taxonomic study was carried out on strain L6M1-5(T), which was isolated from deep-sea sediment collected from the South Atlantic Ocean. The isolate was Gram-reaction-negative, oxidase-negative and catalase-weakly positive. Growth was observed in the presence of 0.5-15% (w/v) NaCl (optimum 3-5%), at 10-41 °C (optimum 28-30 °C), and pH 5.0-10.5 (optimum pH 7.0). The principal fatty acids were summed feature 8 (C18 : 1ω7c/ω6c) (84.2%), C18 : 0 (6.3%), C12 : 1 3-OH (3.2%) and C16 : 0 (2.7%). The polar lipid profile comprised phosphatidylethanolamine, phosphatidylglycerol, two unidentified aminolipids, two unknown phospholipids and one unknown lipid. Ubiquinone-10 was the major quinone. The G+C content of the genomic DNA was 66.0 mol %. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain L6M1-5(T) belonged to the genus Mameliella and shared 95.8% sequence similarity with Mameliella alba JLT354-W(T). The combined genotypic and phenotypic data show that strain L6M1-5(T) represents a novel species of the genus Mameliella, for which the name Mameliella. atlantica sp. nov. is proposed. The type strain is L6M1-5(T) ( = MCCC 1A07531(T) = JCM 30230(T)).
