Heterotrophic bacteria isolated from water samples taken from Hiroshima Bay, Japan, and referred to as Alexandrium (Dinophyceae) cyst formation-promoting bacteria, were assigned to the Roseobacter–Sulfitobacter–Silicibacter group within the α-Proteobacteria on the basis of nearly complete 16S rRNA gene sequences. Phylogenetic analyses showed that two strains, CFPB-A9T and CFPB-A5, are closely related to each other and that their closest relative was Jannaschia helgolandensis (95·9 % sequence similarity). These strains were Gram-negative, motile, obligately aerobic rods that required sodium ions and 2–7 % sea salts for growth and did not produce bacteriochlorophyll a. Their optimal growth temperature was 25–30 °C. The strains had Q-10 as the dominant respiratory quinone. Primary cellular fatty acid in both strains was 18 : 1ω7c. The DNA G+C contents of strains CFPB-A9T and CFPB-A5 were 59·1 and 59·2 mol%, respectively. Based on physiological, biological, chemotaxonomic and phylogenetic data, the strains are considered to represent a novel species, Jannaschia cystaugens sp. nov., with type strain CFPB-A9T (=LMG 22015T=NBRC 100362T).

A novel Gram-stain-negative, facultatively anaerobic, catalase- and oxidase-positive, non-motile and pink-pigmented bacterium, designated G22T, was isolated from Gahai, a saltwater lake in Qinghai province, China. Optimal growth occurred at 33–35 °C, pH 7.0–7.5, and in the presence of 2–4 % (w/v) NaCl. The DNA G+C content was 40.0 mol%. The major polar lipids were phosphatidylethanolamine and three unknown lipids. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH, and MK-7 was the main respiratory quinone. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain G22T fell within the class Bacteroidia . Its closest phylogenetic neighbour was the recently described species Draconibacterium orientale , the sole member of the family Draconibacteriaceae , with merely 90.04 % sequence similarity. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence observed, a novel species in a new genus, Tangfeifania diversioriginum gen. nov., sp. nov., is proposed within the family Draconibacteriaceae . The type strain is G22T ( = CICC 10587T = DSM 27063T).

Isopora Palifera

A bacterial strain, designated SW-3T, was isolated from the reef-building coral Isopora palifera, from Southern Taiwan, and was characterized by using a polyphasic taxonomic approach. Cells of strain SW-3T were Gram-reaction-negative, aerobic, rod-shaped and motile by means of monopolar flagella and formed cream–white colonies. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain SW-3T belonged to the genus Paracoccus and its most closely related neighbours were P. aestuarii B7T, P. homiensis DD-R11T, P. marinus KKL-A5T, P. denitrificans DSM 413T and P. zeaxanthinifaciens R-1512T, with sequence similarities of 96.8, 96.6, 96.1 , 95.8 and 94.9 %, respectively. Strain SW-3T exhibited optimal growth at 25–30 °C and pH 9–10 and in 3–5 % (w/v) NaCl. The predominant cellular fatty acid was summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c; 75 %). The major respiratory quinone was Q-10. The polar lipid profile consisted of a mixture of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and several uncharacterized polar lipids. The DNA G+C content of strain SW-3T was 63.7 mol%. The results of physiological and biochemical tests allowed clear phenotypic differentiation of this isolate from recognized species of the genus Paracoccus. It is evident from the genotypic, phenotypic and chemotaxonomic data that strain SW-3T represents a novel species of the genus Paracoccus, for which the name Paracoccus isoporae sp. nov. is proposed. The type strain is SW-3T ( = LMG 25205T  = BCRC 17967T).

Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SW230T shared highest similarity with members of the genus Dokdonia (95.0–94.5 %), exhibiting 95.0 % sequence similarity to Dokdonia genika NBRC 100811T. Optimal growth occurred in the presence of 2–3 % (w/v) NaCl, at pH 8.0 and at 28 °C. The DNA G+C content of strain SW230T was 36 mol%. The major fatty acids (>10 % of the total) were iso-C15:1 G, iso-C15:0, iso-C17:0 3-OH, and C16:1 ω7c and/or C16:1ω6c. The major respiratory quinone was menaquinone-6. The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and two unidentified lipids. On the basis of data from the present polyphasic study, strain SW230T is considered to represent a novel species of the genus Dokdonia, for which the name Dokdonia pacifica sp. nov. is proposed. The type strain is SW230T ( = CGMCC 1.12184T = JCM 18216T).

Strain NHI-1T is a Gram-negative, motile, non-spore-forming bacterium isolated from oil-contaminated soil in South Korea. The strain was able to grow by using gasoline, diesel and kerosene as energy and carbon sources. After incubation for 14 days, cells (1 g l− 1) degraded approximately 58 % of oil present at concentration of 1500 p.p.m. at pH 8 and 28 °C. Strain NHI-1T grew well under aerobic conditions, with optimal growth at pH 7–9 and 28 °C–37 °C but grew poorly in the presence of ≥ 0.5 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the closest relatives of strain NHI-1T were Aquabacterium fontiphilum CS-6T (97.96 % sequence similarity), Aquabacterium parvum B6T (96.39 %), Aquabacterium commune B8T (95.76 %), Aquabacterium limnoticum ABP-4T (95.72 %) and Aquabacterium citratiphilum B4T (95.25 %). DNA–DNA relatedness was 41–53 % between strain NHI-1T and its closest type strains. The major fatty acids present in strain NHI-1T were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c, 44.5 %), summed feature 8 (C18 : 1ω7c/C18 : 1ω6c, 21.5 %) and C16 : 0 (16.2 %), and the predominant polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidylserine, diphosphatidylglycerol and uncharacterized aminophospholipids. Strain NHI-1T was distinguishable from other members of genus Aquabacterium based on phenotypic, chemotaxonomic and genotypic characteristics. Therefore, strain NHI-1T represents a novel species of the genus Aquabacterium for which the name Aquabacterium olei sp. nov. is proposed. The type strain is NHI-1T ( = KEMB 9005-082T =  KACC 18244T = NBRC 110486T).

Abstract Gram-stain-negative, aerobic, non-flagellated strains 172403-2T and BT310T were isolated from the soil collected in Pyeongchang city and Uijeongbu city, Korea. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strains 172403-2T and BT310T formed a distinct lineage within the family Hymenobacteraceae (order Chitinophagales, class Chitinophagia) and were most closely related to members of the genus Pontibacter, Pontibacter chitinilyticus 17gy-14T (95.7%), and Pontibacter populi HLY7-15T (97.1% 16S rRNA gene sequence similarity) respectively. The optimal growth of strains 172403-2T and BT310T occurred at pH 7.0, in the absence of NaCl, and 25°C and 30°C, respectively. The predominant cellular fatty acids were iso-C15:0 and summed feature 4 (iso-C17:1 I / anteiso-C17:1 B). The major respiratory quinone of the two strains was MK-7. The major polar lipid of the two strains was phosphatidylethanolamine. Biochemical, chemotaxonomic and phylogenetic analyses indicated that strains 172403-2T and BT310T represent novel bacterial species within the genus Pontibacter, for which the names Pontibacter rubellus and Pontibacter situs are proposed. The type strains of Pontibacter rubellus and Pontibacter situs are 172403-2T and BT310T, respectively.
