Abstract
An aerobic, Gram-negative, motile, rod-shaped bacterium designated KMM 9500(T) was isolated from a sediment sample collected from the Sea of Japan seashore. Comparative 16S rRNA gene sequence analysis affiliated strain KMM 9500(T) to the genus Pseudomonas as a distinct subline clustered with Pseudomonas marincola KMM 3042(T) and Pseudomonas segetis KCTC 12331(T) sharing the highest similarities of 98 and 97.9 %, respectively. Strain KMM 9500(T) was characterized by mainly possessing ubiquinone Q-9, and by the predominance of C18:1 ω7c, C16:1 ω7c, and C16:0 followed by C12:0 in its fatty acid profile. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unknown aminophospholipid, and unknown phospholipids. Strain KMM 9500(T) was found to inhibit growth of Gram-negative and Gram-positive indicatory microorganisms. Based on the phylogenetic analysis and distinctive phenotypic characteristics, strain 9500(T) is concluded to represent a novel species of the genus Pseudomonas, for which the name Pseudomonas glareae sp. nov. is proposed. The type strain of the species is strain KMM 9500(T) (=NRIC 0939(T)).

Abstract
A group of five Gram-negative, aerobic, halotolerant, non-pigmented bacteria isolated from shallow sediment samples and invertebrate specimens collected from the Gulf of Alaska and the Sea of Japan was subjected to taxonomic study. On the basis of 16S rRNA gene sequence analysis, the novel isolates were affiliated to the genus Cobetia, sharing the highest sequence similarity of 99.3-99.9 % with Cobetia marina DSM 4741(T). DNA-DNA hybridization experiments between and among the novel strains and C. marina DSM 4741(T) and Cobetia crustatorum JCM 15644(T) revealed that the five strains represent three separate genospecies, which could be differentiated in their morphological, physiological and biochemical characteristics. Halomonas halodurans NBRC 15607(T) was included in this study as it has recently been reported to exhibit high 16S rRNA gene sequence similarity to C. marina DSM 4741(T), and it showed a high DNA relatedness value of 96 % with C. marina DSM 4741(T), indicating that they belong to the same species. On the basis of phylogenetic analysis, DNA-DNA hybridization and phenotypic characterization, three novel species are proposed, named Cobetia amphilecti sp. nov. (type strain KMM 1561(T) = NRIC 0815(T) = CCUG 49560(T)), Cobetia litoralis sp. nov. (type strain KMM 3880(T) =NRIC 0814(T) =CCUG 49563(T)) and Cobetia pacifica sp. nov. (type strain KMM 3879(T) = NRIC 0813(T) = CCUG 49562(T)). It is also proposed that Halomonas halodurans is a later heterotypic synonym of Cobetia marina, and emended descriptions of the genus Cobetia and the species Cobetia marina are provided.

Abstract
Two Gram-negative, aerobic, non-pigmented, non-motile, rod-shaped bacteria, strains KMM 9015 and KMM 9018T, were isolated from a sample of shallow sediment collected from the Sea of Japan. An analysis of the nearly complete 16S rRNA gene sequences showed that the isolates were very close to each other phylogenetically (99.9 % sequence similarity) and their close relatives were Marinovum algicola FF3T (95.8 and 95.9 %, respectively) and members of the genera Leisingera (95.7–95.1 and 95.8–95.2 %), Phaeobacter (95.0–94.2 and 95.1–94.2 %) and Thalassobius (96.3–94.8 and 96.2–94.7 %) of the class Alphaproteobacteria. In phylogenetic trees based on 16S rRNA gene sequences, strains KMM 9015 and KMM 9018T were positioned as a distinct phylogenetic line adjacent to Marinovum algicola. The major isoprenoid quinone was Q-10, the polar lipids consisted of phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unknown lipid and the major fatty acid was C18 : 1ω7c, followed by 11-methyl C18 : 1ω7c, in both strains. The DNA G+C contents of strains KMM 9015 and KMM 9018T were 60.2 and 61.9 mol%, respectively. Based on distinctive phenotypic characteristics and phylogenetic analysis, strains KMM 9015 and KMM 9018T represent a novel species in a novel genus, for which the name Primorskyibacter sedentarius gen. nov., sp. nov. is proposed. The type strain of Primorskyibacter sedentarius is strain KMM 9018T ( = NRIC 0784T = JCM 16874T).

Abstract
A novel actinobacterium, designated KMM 3890 was isolated from a bottom sediment sample collected from the Sakhalin shallow environment. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated strain KMM 3890 affiliation to the genus Citricoccus. In addition to its hemolytic activity, this strain exhibited inhibitory activity against Gram-positive bacteria. It was found that the marine isolate Citricoccus sp. KMM 3890 produced and excreted into the culture medium a large amount of the compound, which was isolated and structurally characterized as known cyclic siderophore nocardamine on the basis of combined spectral analyses. Nocardamine showed inhibitory effects to colony formation of T-47D, SK-Mel-5, SK-Mel-28 and PRMI-7951 tumor cell lines and a weak antimicrobial against Gram-positive bacteria and no revealed cytotoxic activity. This study can be considered as the first report on marine isolate of the genus Citricoccus producing nocardamine with antitumor activity.

Abstract
Two Gram-negative, strictly aerobic, non-motile bacteria designated strains KMM 3851T and KMM 3842T were respectively isolated from a marine snail specimen (Umbonium costatum) and from surrounding sediments collected simultaneously from the shore of the Sea of Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strains KMM 3851T and KMM 3842T were affiliated with the Roseobacter lineage of the class Alphaproteobacteria as a separate phylogenetic line adjacent to the members of the genus Thalassobacter. These novel isolates shared 98.5 % 16S rRNA gene sequence similarity and 15 % DNA–DNA relatedness. The major isoprenoid quinone of both strains was Q-10 and polar lipids consisted of phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and aminophospholipids. In addition, strain KMM 3851T contained two unknown lipids, whereas strain KMM 3842T contained diphosphatidylglycerol. Fatty acid analysis revealed C18 : 1
ω7c and C16 : 0 as major components and small amounts of C18 : 2. The DNA G+C contents were 60.4 mol% (KMM 3851T) and 58.5 mol% (KMM 3842T). Based on distinctive phenotypic characteristics, DNA–DNA hybridization data and phylogenetic distance, strains KMM 3851T and KMM 3842T should be classified as representatives of two novel species in a new genus, Litoreibacter gen. nov., with the type species Litoreibacter albidus sp. nov. (type strain KMM 3851T =NRIC 0773T =JCM 16493T) and a second species Litoreibacter janthinus sp. nov. (type strain KMM 3842T =NRIC 0772T =JCM 16492T).

Abstract
Three Gram-negative, aerobic, halophilic, non-motile, yellowish-pigmented bacteria, designated KMM 3896, KMM 3897 and KMM 3899T, were isolated from coastal seawater and sediment samples of the Sea of Japan, Russia. The isolates were shown to belong to the same species on the basis of 16S rRNA gene sequence similarities (99.6–99.9 %) and DNA–DNA relatedness (73–98 %). Phylogenetic analysis of 16S rRNA gene sequences demonstrated that the isolates formed a subcluster within the genus Kangiella in the class Gammaproteobacteria. 16S rRNA gene sequence similarities between strain KMM 3899T and its closest phylogenetic neighbours, Kangiella koreensis SW-125T and Kangiella aquimarina SW-154T, were 96.6 and 95.5 %, respectively. On the basis of phenotypic differences and phylogenetic distances, it is proposed that strains KMM 3896, KMM 3897 and KMM 3899T are assigned to a novel species of the genus Kangiella, Kangiella japonica sp. nov. The type strain is KMM 3899T (=NRIC 0764T =JCM 16211T).

Abstract
A Gram-negative, aerobic, greyish–yellowish-pigmented, stenohaline, rod-shaped, non-motile bacterium, strain KMM 3900T, was isolated from a coastal seawater sample collected from the Sea of Japan. Based on phylogenetic analysis, strain KMM 3900T was positioned within the Gammaproteobacteria on a separate branch adjacent to members of the genera Reinekea and Kangiella, sharing less than 88 % 16S rRNA gene sequence similarity with all recognized species of the Gammaproteobacteria. The major isoprenoid quinone was Q-8. Polar lipids consisted of phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and two unknown phospholipids. Fatty acid analysis revealed iso-C15 : 0, C16 : 1
ω7c and C16 : 0 as the dominant components. The DNA G+C content was 43.8 mol%. Based on its unique phenotypic characteristics and phylogenetic remoteness, marine isolate KMM 3900T is considered to represent a novel genus and species, for which the name Marinicella litoralis gen. nov., sp. nov. is proposed. The type strain of Marinicella litoralis is KMM 3900T (=NRIC 0758T =JCM 16154T).

Abstract
Two new angucyclines, saccharothrixmicines A (2) and B (3), together with three known diketopiperazines 4-6 were isolated from the actinomycete Saccharothrix espanaensis An 113 associated with the marine mollusk Anadara broughtoni. Their structures were determined by HRESI-MS and 1D and 2D NMR. Compounds 2 and 3 differ in aglycone and glycosidic bond type. 2 is an alpha-L-6-deoxyaltrose-phenylglycoside of a benz[a]anthraquinone aglycone, while 3 is an O-glycoside of the same sugar linked to C-7 of the known angucyclinone (1). A saccharothrixmicine-containing fraction exhibited activity towards Candida albicans and Xanthomonas sp. pv. badrii whereas the diketopiperazines showed antibiotic activities against Vibrio alginolyticus and Vibrio parahaemolyticus.

Abstract
A Gram-stain-negative, aerobic, yellow-pigmented, heterotrophic, sulfur-oxidizing, non-motile, rod-shaped bacterium, designated KMM 3898(T), was isolated from an internal tissue of the sand snail Umbonium costatum, collected from the shallow sediments of the Sea of Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain KMM 3898(T) formed a distinct phylogenetic lineage within the class Gammaproteobacteria and was most closely related to Leucothrix mucor DSM 2157(T) (89.2 % 16S rRNA gene sequence similarity) and members of the genus Thiothrix (86.7-88.5 %). Chemotaxonomically, strain KMM 3898(T) contained the isoprenoid quinone Q-8, the polar lipids phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and an unknown phospholipid and the fatty acids C(18 : 1)ω7c, C(16 : 1)ω7c and C(16 : 0) as predominant components (>10 %). The DNA G+C content of strain KMM 3898(T) was 43.4 mol%. On the basis of phenotypic features and phylogenetic analysis, strain KMM 3898(T) represents a novel genus and species, for which the name Cocleimonas flava gen. nov., sp. nov. is proposed. The type strain is KMM 3898(T) (=NRIC 0757(T) =JCM 16494(T)).

Abstract
The phenotypic and phylogenetic characteristics of an aerobic, Gram-negative, motile, non-pigmented Alteromonas-like bacterium (designated strain KMM 3894T), isolated from a sandy sediment sample collected offshore of the Sea of Japan, were investigated. Comparative 16S rRNA gene sequence analysis revealed that strain KMM 3894T belonged to the genus Aestuariibacter and was most closely related to Aestuariibacter halophilus JC2043T (95.5 % sequence similarity). Fatty acid analysis showed C16 : 1
ω7c, C18 : 1
ω7c, and C16 : 0 as the dominant components. Strain KMM 3894T could be differentiated from recognized species of the genus Aestuariibacter by its ability to grow at 4 °C and at 30 °C, the optimum temperature for growth, and its inability to utilize most carbohydrates. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, strain KMM 3894T is considered to represent a novel species of the genus Aestuariibacter, for which the name Aestuariibacter litoralis sp. nov. is proposed. The type strain is KMM 3894T (=NRIC 0754T=JCM 15896T).

Abstract
Two bacterial strains, KMM 3891(T) and KMM 3892, were isolated from internal tissues of the marine mollusc Umbonium costatum collected from the Sea of Japan. The novel isolates were Gram-negative, aerobic, faint pink-reddish-pigmented, rod-shaped, non-motile, stenohaline and psychrotolerant bacteria that were unable to degrade most tested complex polysaccharides. Polar lipids consisted of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. Fatty acid analysis revealed C(17 : 1)omega6c, C(17 : 0), C(16 : 0) and C(16 : 1)omega7c as the dominant components. The major isoprenoid quinone was Q-7. The DNA G+C content of strain KMM 3891(T) was 51.7 mol%. According to phylogenetic analysis of 16S rRNA gene sequences, strains KMM 3891(T) and KMM 3892 were positioned within the Gammaproteobacteria as a separate branch, sharing <93 % sequence similarity to their phylogenetic relatives including Saccharophagus degradans, Microbulbifer species, Endozoicomonas elysicola, Simiduia agarivorans and Teredinibacter turnerae. Based on phenotypic characterization and phylogenetic distance, the novel marine isolates KMM 3891(T) and KMM 3892 represent a new genus and species, for which the name Umboniibacter marinipuniceus gen. nov., sp. nov. is proposed. The type strain of Umboniibacter marinipuniceus is KMM 3891(T) (=NRIC 0753(T) =JCM 15738(T)).
