Tidal Flat Sediment

A Gram-stain-negative, non-spore-forming, non-motile, strictly aerobic, rod-shaped bacterial strain, designated CAU 1002T, was isolated from a tidal flat sediment and its taxonomic position was investigated using a polyphasic approach. Strain CAU 1002T grew optimally at 30 °C and pH 7.5. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1002T formed a distinct lineage within the genus Algoriphagus and was most closely related to Algoriphagus lutimaris KCTC 22630T and Algoriphagus halophilus KCTC 12051T (97.75 and 97.74 % 16S rRNA gene sequence similarity, respectively). The strain contained MK-7 as the major isoprenoid quinone and iso-C15 : 0 and C16 : 1ω7c and/or iso-C15 : 0 2-OH (summed feature 3) as the major fatty acids. The cell-wall peptidoglycan of strain CAU 1002T contained meso-diaminopimelic acids. The major whole-cell sugars were glucose, arabinose, sucrose, and ribose. The polar lipid profile was composed of phosphatidylethanolamine, five unidentified aminolipids, one unidentified aminophospholipid, one unidentified phospholipid, one unidentified aminoglycolipid, one unidentified glycolipid and twelve unidentified lipids. The DNA G+C content of strain CAU 1002T was 38.0 mol%. On the basis of phylogenetic inference, phenotypic, chemotaxonomic and genotypic data, strain CAU 1002T should be classified into the genus Algoriphagus as a member of a novel species, for which the name Algoriphagus chungangensis sp. nov. is proposed. The type strain is CAU 1002T ( = KCTC 23759T = CCUG 61890T). The description of the genus Algoriphagus is emended.

Tidal Flat Sediment

A Gram-stain-negative, non-motile, non-spore-forming, rod-shaped bacterial strain, BB-Mw22T, was isolated from a tidal flat sediment of the South Sea in South Korea. It grew optimally at 30–37 °C, at pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain BB-Mw22T belonged to the genus Kangiella and the cluster comprising Kangiella species and strain BB-Mw22T was clearly separated from other taxa. Strain BB-Mw22T exhibited 95.3–98.7 % 16S rRNA gene sequence similarity to the type strains of recognized Kangiella species. Strain BB-Mw22T contained Q-8 as the predominant ubiquionone and iso-C15 : 0 and iso-C11 : 0 3-OH as the major fatty acids. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and one unidentified aminolipid. The DNA G+C content of strain BB-Mw22T was 48.9 mol%, and its mean DNA–DNA hybridization values with Kangiella geojedonensis YCS-5T, Kangiella japonica JCM 16211T and Kangiella taiwanensis JCM 17727T were 14–28 %. Phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain BB-Mw22T is distinguishable from all recognized Kangiella species. On the basis of the data presented, strain BB-Mw22T is considered to represent a novel species of the genus Kangiella , for which the name Kangiella sediminilitoris sp. nov. is proposed.

Two marine bacterial strains, designated S2-4-21T and MT2-5-19, were isolated from two tidal flat sediments of cordgrass Spartina alterniflora and adjacent oyster culture field in Quanzhou bay, China, respectively. Both strains were Gram-staining-negative, rod-shaped, non-flagellated, non-motile, aerobic, had NaCl requirements, and contained carotenoid and flexirubin pigments. The 16S rRNA gene sequence similarity (99.8%), average nucleotide identity value (99.4%) and average amino acid identity (99.3%) between strain S2-4-21T and strain MT2-5-19 strongly supported that they belonged to a single species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S2-4-21T and strain MT2-5-19 formed a monophyletic branch affiliated to the family Flavobacteriaceae , sharing similarities of 94.6% with Euzebyella marina CY01T and E. saccharophila 7SM30T, and of 94.1 and 92.8% with E. algicola MEBiC 12267T and Pseudozobellia thermophile DSM 19858T, respectively. Phylogenomic analysis based on the whole genome sequences supported that the two strains formed a distinct monophyletic clade within Flavobacteriaceae members, which was phylogenetically different from the clades of Euzebyella and Pseudozobellia . The major respiratory quinone was menaquinone MK-6. The major fatty acids (>10%) consisted of C15 : 0 iso, C16 : 0, summed feature 9 (C17 : 1 iso ω9c/C16 : 0 10-methyl) and C17 : 0 iso 3-OH. The polar lipid profiles of strain S2-4-21T and strain MT2-5-19 are identical, including phosphatidylethanolamine, four unidentified aminolipids, and four unidentified lipids. The genomic size was 4.9–5.0 Mb with genomic DNA G+C content of 41.5 mol%. Based on the above characteristics, strains S2-4-21T and MT2-5-19 represented a novel species of a novel genus in the family Flavobacteriaceae . Thus, Pareuzebyella sediminis gen. nov. sp. nov. is proposed with type strain S2-4-21T (=MCCC 1K03818T=KCTC 72152T), and another strain MT2-5-19 (=KCTC 72539=MCCC 1K03874).

A novel Gram-staining-negative, strictly aerobic bacterium, designated BS14T, was isolated from a marine tidal flat of the South Sea in Korea. Colonies were opaque, white, smooth and circular on marine agar. Cells were moderately halophilic, non-motile rods showing catalase- and oxidase-positive reactions. Growth of strain BS14T was observed at 5–40 °C (optimum: 30 °C), pH 6.5–9.5 (optimum: 7.0–7.5) and 0–10 % (w/v) NaCl (optimum: 1–1.5 %). The G+C content of the genomic DNA was 61.6 mol%. Strain BS14T contained ubiquinone-10 (Q-10) as the sole respiratory quinone and summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), C18 : 0 3-OH, C10 : 0 3-OH and C18 : 0 as the major fatty acids. The polar lipid pattern comprised phosphatidylethanolamine, diphosphatidylglycerol, an unidentified aminolipid, an unidentified phospholipid and an unidentified polar lipid. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BS14T formed a tight phylogenetic lineage with Defluviimonas denitrificans D9-3T with a bootstrap value of 100 %. The 16S rRNA gene sequence similarity between strain BS14T and D. denitrificans D9-3T was 97.4 % and their DNA–DNA relatedness was 19.1±3.6 %. Based on the phenotypic and genotypic studies, strain BS14T represents a novel species of the genus Defluviimonas , for which the name Defluviimonas aestuarii sp. nov. is proposed. The type strain is BS14T ( = KACC 16442T = JCM 18630T). An emended description of the genus Defluviimonas Foesel et al. 2011 is also proposed.

Molecular Features

A Gram-stain-negative, ochre-pigmented, strictly aerobic bacterium, designated strain KJ7T, was isolated from a tidal flat of the Gangjin bay in South Korea. Cells were halotolerant, non-motile, catalase- and oxidase-positive rods. Growth of strain KJ7T was observed at 5–35 °C (optimum, 25 °C), at pH 6.0–9.5 (optimum, pH 6.5–7.0) and in the presence of 0–9 % (w/v) NaCl (optimum, 2 %). The major cellular fatty acids were C18 : 1ω7c, C17 : 1ω6c, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The polar lipid pattern indicated the presence of phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, a sphingoglycolipid, an unidentified phospholipid and two unidentified lipids. The G+C content of the genomic DNA was 60.2±0.9 mol% and the predominant respiratory quinone was Q-10. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain KJ7T formed a phyletic lineage distinct from other members of the genus Altererythrobacter and was most closely related to Altererythrobacter luteolus SW-109T and Altererythrobacter namhicola KYW48T (95.6 and 95.0 % 16S rRNA gene sequence similarity, respectively). On the basis of phenotypic, chemotaxonomic and molecular features, strain KJ7T represents a novel species of the genus Altererythrobacter , for which the name Altererythrobacter gangjinensis sp. nov. is proposed. The type strain is KJ7T ( = KACC 16190T = JCM 17802T).
