“…Cells were disrupted using a sonicator (Ohtake Works, Japan) and extracted by the acetone-methanol (70:30, vol/vol) method. There are 12 currently recognized species in the Jannaschia genus, which contains only two BChl a -producing species ( Jannaschia seohaensis and Jannaschia formosa [ 2 , 3 ], respectively).…”

“…The majority of these species are marine in origin, but some genera of terrestrial origin exist [7]. They have been isolated from seawater [8,9], marine sediments [10,11] and biofilms, and are often associated with phytoplankton, macroalgae [12] and marine animals [13]. The members of this group also possess a great deal of physiological diversity, which is capable of metabolizing a large number of carbon sources, synthesizing B vitamins to facilitate eukaryotic interactions, assimilatory and dissimilatory nitrate reduction, and phototrophic growth [14].…”

Three Gram-staining-negative, aerobic and rod-shaped strains, designated as T40-1T, T40-3T and JL-62T, were isolated from the deep-sea water in the southwest Indian ridge. For strain T40-1T, growth occurred at 15–37 °C (optimum, 28 °C), pH 6.0–9.0 (optimum, pH 7.5) and in the presence of 0.5–5.0 % NaCl (w/v; optimum, 2.0 %). Strain T40-3T could grow at 15–40 °C (optimum, 28 °C), with 0.5–11.0 % NaCl (optimum, 2.0 %, w/v) at pH 6.0–9.5 (optimum, 8.0). The temperature, pH and salinity ranges for growth of strain JL-62T were 15–40 °C (optimum, 30 °C), pH 5.5–9.0 (optimum, pH 7.5–8.0) and 0.5–9.0 % NaCl (w/v; optimum, 4.0 %). Ubiquinone-10 was the sole ubiquinone in all strains, the major fatty acids (>20 %) were summed feature 8 (C18 : 1 ω7c / C18 : 1 ω6c). The major polar lipids of strains T40-1T and T40-3T were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. Strain JL-62T contained phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and sulfoquinovosyldiacylglycerol as major polar lipids. Phylogenetic trees based on 16S rRNA gene and core-genomic sequences revealed affiliation of strains T40-1Tand T40-3T to the family Roseobacteraceae and formed two independent clades from other Roseobacteraceae genera, and those two strains had average nucleotide identities of 62.0–72.0 % to their phylogenetically related species which fell into to the genus boundary range, indicating that they represent two novel genera. While strain JL-62T represents a novel species in the genus Oricola belonging to the family Phyllobacteriaceae , which was supported by overall genomic relatedness index calculations. The DNA G+C contents of strains T40-1T, T40-3T and JL-62T were 66.5, 60.1 and 62.1 mol %, respectively. Based on the polyphasic taxonomic data, strains T40-1T (=MCCC M24557T=KCTC 82975T) and T40-3T (=MCCC 1K05135T=KCTC 82976T) are classified as representing two novel genera belonging to the family Roseobacteraceae with the names Mesobacterium pallidum gen. nov., sp. nov. and Heliomarina baculiformis gen. nov., sp. nov. are proposed, and strain JL-62T (=MCCC M24579T=KCTC 82974T) is proposed to represent a novel species within the genus Oricola with the name Oricola indica sp. nov. is proposed.

“…At present, this family comprises 183 genera and more than 500 species with validly published names [3]. Indeed, approximately more than 70 % of the genera originated from diverse coastal marine environments, such as deep-sea water [4][5][6][7], alga [8], coral [9] and marine sediment [10,11]. Members from the marine genera Antarctibacter, Celeribacter and Leisingera possess properties that degrade a wide variety of organic compounds including dimethylsulfoniopropionate, polycyclic aromatic hydrocarbons and monohalomethanes [12][13][14].…”

Members within the family Rhodbacteraceae are morphologically and genetically highly diverse, and originate mostly from coastal marine environments. In this study, a novel species of this family, designated M0103T, was isolated from the surface of a sea snail Littorina scabra. Strain M0103T is Gram-stain-negative, halophilic, non-motile and non-Bacteriochlorophyll a-producing bacterium. Several phenotypic characteristics of the isolate were similar to other species within this family, such as the sole respiratory quinone Q-10 and major fatty acid components C18 : 1 ω7c, C18 : 0 and C16 : 0. Strain M0103T contains a diphosphatidylglycerol, a phosphatidylglycerol, a phosphatidylcholine, a phosphatidy ethanolamine, a phosphatidylinositol, five unidentified phospholipids and four unidentified polar lipids. Based on the 16S rRNA gene sequence analysis, this isolate showed the closest phylogenetic relationship with ‘ Palleronia pontilimi ’ GH1-23T (95.1 %). Values of average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) of genome sequences were of 70.1–76.4 % and 18.3–20.9 % between the isolate and 24 closely related type strains. Analysis the 4.0 Mb genome of strain M0103T revealed several putative genes associated with cellular stress resistance, which may play protective roles for the isolate in the adaptation to a marine environment. Phylogenetic, phenotypic and chemotaxonomic analyses suggested that strain M0103T represents a novel genus and novel species of the family Rhodobacteraceae , for which the name Mesobaculum littorinae gen. nov., sp. nov. is proposed. The type strain is M0103T (=MCCC 1K03619T=KCTC 62358T).
