A Gram-staining-negative, motile, weakly halophilic and facultatively aerobic bacterium, designated strain YA11T, was isolated from tidal flat sediment at Yeongam Bay, South Korea. Strain YA11T grew at 10–30 °C (optimum, 20 °C), at pH 6.0–10.0 (optimum, pH 6.5–7.5) and in the presence of 1–6 % (w/v) NaCl (optimum, 2–3 %). The major cellular fatty acids of the strain were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The DNA G+C content of the genomic DNA was 44.2 mol%. Strain YA11T contained Q-8 as the sole respiratory quinone. A phylogenetic tree based on 16S rRNA gene sequences showed that strain YA11T formed a distinct phyletic lineage within the genus Photobacterium and the 16S rRNA gene sequence similarities between strain YA11T and the type strains of species of the genus Photobacterium ranged between 94.0 and 96.4 %. Based on the phenotypic, chemotaxonomic and molecular properties, strain YA11T represents a novel species of the genus Photobacterium , for which the name Photobacterium aestuarii sp. nov. is proposed, with strain YA11T( = KACC 16912T = JCM 18592T) as the type strain.

A Gram-staining-negative, non-motile, catalase- and oxidase-positive strain, designated CCNWSP36-1T, was isolated from the nodule surface of soybean [Glycine max (L.) Merrill] cultivar Zhonghuang 13. The 16S rRNA gene sequence analysis clearly showed that the isolate represented a member of the genus Sphingobacterium . On the basis of pairwise comparisons of 16S rRNA gene sequences, strain CCNWSP36-1T showed 96.8 % similarity to Sphingobacterium nematocida CCTCC AB 2010390T and less than 95.2 % similarity to other members of the genus Sphingobacterium . Growth of strain CCNWSP36-1T occurred at 10–40 °C and at pH 5.0–9.0. The NaCl range (w/v) for growth was 0–4 %. The predominant isoprenoid quinone was MK-7. The polar lipids were phosphatidylethanolamine and several unidentified polar lipids. Sphingolipid was present. The major fatty acids were iso-C15 : 0 and summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c). The G+C content of the genomic DNA was 41.1 mol%. As the physiological and biochemical characteristics of strain CCNWSP36-1T and the type strains of its closest phylogenetic neighbours showed clear differences, a novel species, Sphingobacterium yanglingense, is proposed. The type strain is CCNWSP36-1T ( = ACCC 19328T = JCM 30166T).

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.

A Gram-stain-negative, aerobic, non-spore-forming, motile by single polar flagellum and ovoid or rod-shaped bacterial strain, designated JBTF-M23T, was isolated from tidal flat sediment collected from the Yellow Sea, Republic of Korea. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M23T fell within the clade comprising the type strains of Pseudoalteromonas species, clustering with the type strains of P. byunsanensis and P. amylolytica . Strain JBTF-M23T exhibited the highest 16S rRNA gene sequence similarity value (98.6 %) to the type strain of P. rubra and sequence similarities of 98.3 and 97.7 % to the type strains of P. byunsanensis and P. amylolytica, respectively. The DNA G+C content of strain JBTF-M23T from genomic sequence data was 41.98 %. The ANI and dDDH values between strain JBTF-M23T and the type strains of P. rubra , P. byunsanensis and P. amylolytica were 71.3–76.6 and 19.4–19.9 %, respectively. Strain JBTF-M23T contained Q-8 as the predominant ubiquinone and C16 : 1  ω7c and/or C16 : 1  ω6c, C16 : 0 and C18 : 1  ω7c as the major fatty acids. The major polar lipids of strain JBTF-M23T were phosphatidylethanolamine and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M23T is separated from recognized Pseudoalteromonas species. On the basis of the data presented, strain JBTF-M23Tis considered to represent a novel species of the genus Pseudoalteromonas , for which the name Pseudoalteromonas caenipelagi sp. nov. is proposed.

Degrading Bacterium

A Gram-staining-negative, facultatively aerobic bacterium, designated SM-2T, was isolated from a sea-tidal flat of Yellow Sea, South Korea. Cells were catalase- and oxidase-positive motile rods with a single polar flagellum. Growth of strain SM-2T was observed at 10–37 °C (optimum, 25–30 °C), at pH 5.5–8.5 (optimum, pH 7.0–7.5) and in the presence of 0–11 % (w/v) NaCl (optimum, 2 %). Strain SM-2T contained ubiquinone-8 (Q-8) as the sole isoprenoid quinone and C17 : 1ω8c, summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH), C17 : 0 and C18 : 1ω7c as the major fatty acids. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unidentified lipid were identified as the major cellular polar lipids. The G+C content of the genomic DNA was 52.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SM-2T formed a tight phyletic lineage with Zhongshania antarctica ZS5-23T, Zhongshania guokunii ZS6-22T and Spongiibacter borealis CL-AS9T, but that S. borealis CL-AS9T was distinct from other species of the genus Spongiibacter . Based on 16S rRNA gene sequence similarities, strain SM-2T was most closely related to S. borealis CL-AS9T, Z. antarctica ZS5-23T and Z. guokunii ZS6-22T, with similarities of 99.5 %, 98.9 % and 98.7 %, respectively, but the DNA–DNA hybridization values among these species were clearly lower than 70 %. On the basis of chemotaxonomic data and molecular properties, we propose strain SM-2T represents a novel species of the genus Zhongshania with the name Zhongshania aliphaticivorans sp. nov. (type strain SM-2T = KACC 18120T = JCM 30138T). We also propose the transfer of Spongiibacter borealis Jang et al. 2011 to the genus Zhongshania as Zhongshania borealis comb. nov. (type strain CL-AS9T = KCCM 90094T = JCM 17304T).
