“…alba. The predominant isoprenoid quinone detected in strain MM-10 T was ubiquinone-10 (Q-10), which is compatible with that of M. alba and A. heliothermus (Zheng et al, 2010;Labreuz et al, 1998). The fatty acid profile of strain MM-10 T is shown in Table 2, together with those of M. alba LMG 24665 T , S. stellata DSM 11524 T and A. heliothermus DSM 11445 T analysed also in this study.…”

A Gram-stain-negative, coccoid-or oval-shaped and non-motile bacterial strain, designated MM-10 T , belonging to the Alphaproteobacteria, was isolated from seawater of the Yellow Sea, Korea, and was subjected to a polyphasic taxonomic study. Strain MM-10 T grew optimally at pH 7.0-8.0, at 30 C and in the presence of 2-3 % (w/v) NaCl. Neighbour-joining, maximumlikelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain MM-10 T fell within the clade comprising members of the genera Mameliella, Sagittula, Antarctobacter and Ponticoccus. Strain MM-10 T exhibited a 16S rRNA gene sequence similarity of 97.7 % with respect to the type strain of Mameliella alba. The DNA G+C content of strain MM-10 T was 66.0 mol% and its mean level of DNA-DNA relatedness with M. alba LMG 24665 T was 12.3±1.4 % . Strain MM-10 T contained Q-10 as the predominant ubiquinone and C 18 : 1 !7c as the major fatty acid. The major polar lipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. Differential phenotypic properties, together with phylogenetic distinctiveness, demonstrate that strain MM-10 T is distinguishable from recognized species of the genera Mameliella, Sagittula and Antarctobacter. On the basis of the data presented, strain MM-10 T is considered to represent a novel species of a new genus, for which the name Maliponia aquimaris gen. nov., sp. nov. is proposed. The type strain of Maliponia aquimaris is

“…Mameliella alba belongs to the Roseobacter clade in the order Rhodobacterales [4]. Members of the Roseobacter clade are abundant in the marine environments suggesting that they play important roles in marine ecosystems, such as the degradation of aromatic compounds and the biogeochemical cycles of carbon and sulfur [5].…”

Draft genome sequence of Mameliella alba strain UMTAT08 isolated from clonal culture of toxic dinoflagellate Alexandrium tamiyavanichii

Mameliella alba strain UMTAT08 was isolated from clonal culture of paralytic shellfish toxin producing dinoflagellate, Alexandrium tamiyavanichii. Genome of the strain UMTAT08 was sequenced in order to gain insights into the dinoflagellate-bacteria interactions. The draft genome sequence of strain UMTAT08 contains 5.84Mbp with an estimated G + C content of 65%, 5717 open reading frames, 5 rRNAs and 49 tRNAs. It contains genes related to nutrients uptake, quorum sensing and environmental tolerance related genes. Gene clusters for the biosynthesis of type 1 polyketide synthase, bacteriocin, microcin, terpene and ectoine were also identified. This is suggesting that the bacterium possesses diverse adaptation strategy to survive within the dinoflagellate phycosphere. The draft genome sequence and annotation have been deposited at DDBJ/EMBL/GenBank under the accession number JSUQ00000000.

“…Since a Gram-negative bacterium belonging to the Roseobacter clade within the class Alphaproteobacteria was first reported by Shiba (1991), many new genera of the Roseobacter clade have been isolated from various marine environments such as seawater, tidal flats, marine algae, and hypersaline microbial mats (Choi et al, 2007;Lee et al, 2007;Y.-G. Kim et al, 2008;Vandecandelaere et al, 2009;Wang et al, 2009;Yoon et al, 2009;Zheng et al, 2010). The Roseobacter clade is known as one of the most abundant groups in marine environments and its members show diverse physiological and morphological features.…”

A moderately halophilic Gram-staining-negative bacterium, designated strain Y26T, was isolated from a tidal flat of Taean coast in South Korea. Cells were strictly aerobic, motile cocci with a single flagellum and showed catalase- and oxidase-positive reactions. Growth of strain Y26T was observed at 15–35 °C (optimum 25–30 °C), pH 6.0–8.0 (optimum pH 6.5–7.5) and with 1.5–6.0 % (w/v) NaCl (optimum 2.0–3.0 %). The predominant fatty acids were C18 : 1 ω7c (66.2 %), C16 : 0 (12.4 %) and C10 : 0 3-OH (5.0 %) and the G+C content of the genomic DNA was 61.0 mol%. Strain Y26T contained ubiquinone-10 (Q-10) as the major respiratory quinone. Comparative 16S rRNA gene sequence analysis showed that strain Y26T formed a distinct phyletic lineage from other genera within the Roseobacter clade of the class Alphaproteobacteria and was most closely related to members of the genera Maribius, Maritimibacter and Palleronia with 93.8–94.6 % sequence similarity. On the basis of chemotaxonomic data and molecular properties, strain Y26T represents a novel genus, Hwanghaeicola, within the family Rhodobacteraceae, for which the name Hwanghaeicola aestuarii gen. nov., sp. nov. is proposed. The type strain is Y26T (=KACC 13705T =DSM 22009T).
