    ABSTRACT: A novel Gram-negative, aerobic, motile, short rod-shaped bacterium, designated MS-3(T), was isolated from a crude oil-contaminated seashore in Taean, Korea. Strain MS-3(T) grew at 4-30 °C, at pH 6.0-9.5 and with 0-5 % NaCl and was oxidase- and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MS-3(T) was most similar to Pseudomonas marincola KMM 3042(T) (97.9 % 16S rRNA gene sequence similarity), P. cuatrocienegasensis 1N(T) (97.8 %), P. borbori R-20821(T) (97.3 %) and P. lundensis ATCC 49968(T) (97.1 %). Relatively low levels of DNA-DNA relatedness were found between strain MS-3(T) and P. cuatrocienegasensis LMG 24676(T) (57.2 %), P. borbori LMG 23199(T) (39.7 %), P. marincola KMM 3042(T) (32.2 %) and P. lundensis KACC 10832(T) (32.1 %), which support the classification of strain MS-3(T) within a novel species of the genus Pseudomonas. The G+C content of the genomic DNA of strain MS-3(T) was 57.6 mol% and the major isoprenoid quinone was Q-9. Strain MS-3(T) contained summed feature 3 (iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c; 38.0 %), C(16 : 0) (24.4 %), C(18 : 1)ω7c (12.8 %), C(12 : 0) (9.6 %) and C(10 : 0) 3-OH (4.9 %) as the major cellular fatty acids. On the basis of the phenotypic, genotypic and phylogenetic data, strain MS-3(T) represents a novel species of the genus Pseudomonas, for which the name Pseudomonas taeanensis sp. nov. is proposed. The type strain is MS-3(T) (=KCTC 22612(T) =KACC 14032(T) =JCM 16046(T) =NBRL 105641(T)).

    ABSTRACT: A novel strictly aerobic, orange-pigmented, Gram-stain-negative bacterium, designated strain GJ16(T), was isolated from coastal seawater of Gangjin Bay, the southernmost part of the Korean peninsula, and subjected to a polyphasic taxonomic study. It grew optimally at 25-30 °C, at pH 7.0-8.0 and in the presence of 3 % NaCl. Comparative 16S rRNA gene sequence analysis revealed that strain GJ16(T) formed a distinct lineage within the family Flavobacteriaceae and shared less than 91.2 % 16S rRNA gene sequence similarity with members of the genera Leptobacterium, Zhouia, Winogradskyella, Dokdonia and Krokinobacter. The predominant cellular fatty acids were iso-C(15 : 0) (40.2 %), iso-C(15 : 1) G (12.8 %), iso-C(17 : 0) 3-OH (11.2 %) and C(15 : 0) (6.6 %). The G+C content of the genomic DNA was 39.4 mol% and the major respiratory isoprenoid quinone was MK-6. On the basis of phenotypic and genotypic data, strain GJ16(T) represents a novel species in a new genus in the family Flavobacteriaceae, for which the name Gangjinia marincola gen. nov., sp. nov. is proposed; the type strain is GJ16(T) (=KCTC 22649(T) =JCM 16082(T)).

    ABSTRACT: A novel, strictly aerobic, Gram-stain-negative, yellow-orange-pigmented, rod-shaped bacterium was isolated from abalone (Haliotis discus) under aquaculture in seawater off the Wando coast, Southern Korea, and subjected to a polyphasic taxonomic study. Cells of strain Haldis-1(T) were catalase- and oxidase-positive rods with flexirubin pigments. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Haldis-1(T) formed a distinct lineage within the family Cryomorphaceae and could be distinguished from the related genera Lishizhenia and Fluviicola. Strain Haldis-1(T) shared 16S rRNA gene sequence similarities of 92.5 and 92.4 % with Lishizhenia caseinilytica UST040201-001(T) and Fluviicola taffensis RW262(T), respectively. The DNA G+C content was 38.1 mol% and the major respiratory quinone was MK-7. The predominant cellular fatty acids were iso-C(15 : 0) (38.6 %), C(15 : 0) 2-OH (20.3 %) and C(15 : 0) (10.7 %). Growth was observed at 25-42 degrees C (optimum 30-37 degrees C) and at pH 6.5-9.5 (optimum pH 6.5-8.0). On the basis of polyphasic analysis of phenotypic, genotypic and phylogenetic data, strain Haldis-1(T) represents a novel genus and species within the family Cryomorphaceae in the phylum Bacteroidetes, for which the name Wandonia haliotis gen. nov., sp. nov. is proposed. The type strain is Haldis-1(T) (=KCTC 22610(T) =NBRC 105642(T)).
