A Gram-negative, rod-shaped and non-spore-forming bacterial strain, JM27T, was isolated from a tidal flat of Dongtan Wetland, Chongming Island, China. The strain formed smooth yellow colonies on R2A plates. Growth occurred at 10–37 °C (optimum, 30–37 °C), at pH 6.0–10.0 (optimum, pH 7.0–9.0) and in the presence of 0–1 % NaCl (optimum, 0 %). Catalase test was positive and oxidase test was negative. Ubiquinone 10 (Q10) was the major respiratory quinone. C18 : 1ω7c and C17 : 1ω6c were the most abundant fatty acids. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were the major polar lipids. The DNA G+C content of strain JM27T was 66.4 mol%. The 16S rRNA gene sequence of the isolate showed highest similarity to that of Altererythrobacter marinus H32T (96.4 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain belonged to the genus Altererythrobacter of the family Erythrobacteraceae of the class Alphaproteobacteria. On the basis of phylogenetic analysis, whole-cell fatty acids, polar lipid compositions, and biochemical and physiological characteristics, strain JM27T is proposed to represent a novel species of the genus Altererythrobacter for which the name Altererythrobacter dongtanensis sp. nov. is proposed. The type strain is JM27T ( = KCTC 22672T  = CCTCC AB 209199T).

A Gram-negative, yellow-pigmented, rod-shaped, strictly aerobic, non-flagellated, oxidase- and catalase-positive, marine bacterium, designated A2T, was isolated from a marine sponge, Hymeniacidon flavia, collected from the coast of Jeju Island, South Korea. Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that strain A2T was a member of the family Flavobacteriaceae. Its closest relatives were Formosa agariphila KMM 3901T and Formosa algae KMM 3553T (96.99 and 96.98 % 16S rRNA gene sequence similarity, respectively). DNA–DNA relatedness between strain A2T and F. agariphila KMM 3901T and F. algae KMM 3553T was 14.1 and 26.8 %, respectively. The dominant fatty acids (>5 %) of strain A2T were iso-C15 : 0 (33.9 %), iso-C17 : 0 3-OH (20.8 %), iso-C15 : 1 G (10.5 %) and iso-C15 : 0 3-OH (6.1 %). The DNA G+C content of strain A2T was 36.0 mol% and the major respiratory quinone was MK-6. On the basis of phenotypic and phylogenetic analysis, strain A2T represents a novel species of the genus Formosa, for which the name Formosa spongicola sp. nov. is proposed. The type strain is A2T (=KCTC 22662T =DSM 22637T).

A marine bacterium, DOKDO 007T, was isolated from the rhizosphere of the marine alga Ecklonia kurome collected from Dokdo Island, Korea, in October 2004. The strain produced orange-coloured colonies on marine agar 2216. 16S rRNA gene sequence analysis indicated that the novel isolate belonged to the family Flavobacteriaceae and showed relatively high sequence similarities with members of the genus Muricauda (92.0–94.0 %). Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that the novel isolate shared a lineage with members of the genera Muricauda and Costertonia. Cells were aerobic, Gram-negative rods producing non-diffusible carotenoid pigments. In contrast to all other members of the family Flavobacteriaceae, cells of DOKDO 007T were motile by means of a polar flagellum. Optimal growth occurred in the presence of 3.5–4 % (w/v) sea salts (corresponding to 2.7–3.1 % NaCl), at pH 8 and at temperatures of 26–29 °C. The novel strain required Ca2+ ions in addition to NaCl for growth. The dominant fatty acids were iso-15 : 0, iso-15 : 1ω10c and 10-methyl-16 : 0. The major respiratory quinone was MK-6. The DNA G+C content was 56.3 mol%, an unusually high value for members of the family Flavobacteriaceae. On the basis of these polyphasic taxonomic data, strain DOKDO 007T should be classified as representing a new genus and novel species in the family Flavobacteriaceae, for which the name Flagellimonas eckloniae gen. nov., sp. nov. is proposed. The type strain is DOKDO 007T (=KCCM 42307T=JCM 13831T).

A Gram-stain-negative and facultatively anaerobic bacterium, SY21T, was isolated from marine sediments of the coastal area in Weihai, China (122° 0′ 37″ E 37° 31′ 33″ N). Cells of strain SY21T were 0.3–0.5 μm wide and 1.5–2.5 μm long, catalase- and oxidase-positive. Colonies on 2216E agar were transparent, beige- to pale-brown-pigmented, and approximately 0.5 mm in diameter. Growth occurred optimally at 33–37 °C, pH 7.0–7.5 and in the presence of 2–3 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene indicated that strain SY21T was a member of the genus Mariniphaga within the family Prolixibacteraceae. The closest described neighbour in terms of 16S rRNA gene sequences identity was Mariniphaga anaerophila Fu11-5T (94.7 %). The major respiratory quinone of strain SY21T was MK-7, and the dominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and anteiso-C15 : 0. The major polar lipids were phosphatidylethanolamine, aminolipid and an unidentified lipid, and the DNA G+C content was 37.9 mol%. The distinct phylogenetic position and phenotypic traits distinguished the novel isolate from M. anaerophila Fu11-5T. Phenotypic and genotypic analysis indicated that strain SY21T could be assigned to the genus Mariniphaga. The name Mariniphaga sediminis sp. nov. is proposed, with the type strain SY21T ( = KCTC 42260T = MCCC 1H00107T).

An aerobic, Gram-stain-negative rod, designated strain A2P5T, was isolated from the Douro river, in Porto, Portugal. Cells were catalase- and oxidase-positive. Growth occurred at 15–30 °C, at pH 6–8 and in the presence of 1 % (w/v) NaCl. The major respiratory quinone was Q8, the genomic DNA had a G+C content of 47 ± 1 mol%, and phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol were amongst the major polar lipids. On the basis of 16S rRNA gene sequence analysis, strain A2P5T was observed to be a member of the family Burkholderiaceae, but could not be identified as a member of any validly named genus. The low levels of 16S rRNA gene sequence similarity to other recognized taxa ( < 91 %), together with the comparative analysis of phenotypic and chemotaxonomic characteristics, supported the proposal of a novel species of a new genus within the family Burkholderiaceae. The name Hydromonas duriensis gen. nov., sp. nov. is proposed. The type strain of Hydromonas duriensis is A2P5T ( = LMG 28428T = CCUG 66137T).

Two novel strains, SL014B61AT and SL014B11A, were isolated from an oil-polluted saline soil from Gudao in the coastal Shengli Oilfield, eastern China. Cells of strains SL014B61AT and SL014B11A were motile, Gram-negative and rod-shaped. Growth occurred at NaCl concentrations of between 0 and 15 % and at temperatures of between 10 and 45 °C. Strain SL014B61AT had Q9 as the major respiratory quinone and C16 : 0 (21.2 %), C18 : 1ω9c (20.3 %), C16 : 1ω7c (7.3 %) and C16 : 1ω9c (6.4 %) as predominant fatty acids. The G+C content of the DNA was 57.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SL014B61AT belonged to the genus Marinobacter in the class Gammaproteobacteria. Strain SL014B61AT showed the highest 16S rRNA gene sequence similarity with Marinobacter bryozoorum (97.9 %) and showed 97.8 % sequence similarity to Marinobacter lipolyticus. DNA–DNA relatedness to the reference strains Marinobacter bryozoorum and Marinobacter lipolyticus was 35.5 % and 33.8 %, respectively. On the basis of these data, it is proposed that strains SL014B61AT and SL014B11A represent a novel species, Marinobacter gudaonensis sp. nov. The type strain is strain SL014B61AT (=DSM 18066T=LMG 23509T=CGMCC 1.6294T).

Two Gram-stain-negative and non-flagellated bacteria, YSTF-M3T and YSTF-M6T, were isolated from a tidal flat from Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strains YSTF-M3T and YSTF-M6T belong to the genera Kordia and Olleya of the family Flavobacteriaceae , respectively. The 16S rRNA gene sequence similarities between strain YSTF-M3T and the type strains of Kordia species and between strain YSTF-M6T and the type strains of Olleya species were 94.1–98.4 and 97.3–98.3 %, respectively. The ANI and dDDH values between genomic sequences of strain YSTF-M3T and the type strains of five Kordia species and between those of strain YSTF-M6T and the type strains of three Olleya species were in ranges of 77.0–83.2 and 20.7–27.1 % and 79.4–81.5 and 22.3–23.9 %, respectively. The DNA G+C contents of strain YSTF-M3T and YSTF-M6T from genomic sequences were 34.1 and 31.1 %, respectively. Both strains contained MK-6 as predominant menaquinone and phosphatidylethanolamine as only major phospholipid identified. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strains YSTF-M3T and YSTF-M6T are separated from recognized species of the genera Kordia and Olleya , respectively. On the basis of the data presented, strains YSTF-M3T (=KACC 21639T=NBRC 114499T) and YSTF-M6T (=KACC 21640T=NBRC 114500T) are considered to represent novel species of the genera Kordia and Olleya , respectively, for which the names Kordia aestuariivivens sp. nov. and Olleya sediminilitoris sp. nov. are 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).

Abstract Strain SZY PN-1T, representing a novel Gram-negative, aerobic, non-motile, rod-shaped and yellow-pigmented bacterium, was isolated from a skin sample of a healthy Chinese people. Growth of SZY PN-1T optimally occurred at pH 7.0, at 30 ºC and tolerate up to 1.0 % (w/v) NaCl. According to the absorption spectrum, carotenoid was present in the cells. Comparative analysis of the 16S rRNA gene revealed that strain SZY PN-1T shared high similarities with Sandaracinobacter sibiricus RB16-17T (97.1 %) and Sandaracinobacter neustonicus JCM 30734T (96.6 %), respectively. Phylogenetic analysis of 16S rRNA gene sequences together with protein-concatamer tree showed that SZY PN-1T formed a separate branch within the genus Sandaracinobacter. The DNA G+C content of the strain SZY PN-1T was 65.0 % (genome). The polar lipid profile included phosphatidylethanolamine, phosphatidylglycerol, two sphingoglycolipids, diphosphatidylglycerol, five unidentified glycolipids and seven unidentified lipids. The predominant fatty acids (> 10.0 %) were identified as C18:1 ω7c and/or C18:1 ω6c, C17:1 ω6c, C16:1 ω7c and/or C16:1 ω6c. The major respiratory quinone was ubiquinone Q-10. Based on the phenotypic and genotypic features, we proposed Sandaracinobacter hominis sp. nov. with type strain SZY PN-1T (= KCTC 82150T = NBRC 114675T).
