A Gram-negative, rod-shaped, motile and aerobic bacterium, designated strain HJ51T, was isolated from a seawater sample from the East Sea, near South Korea. The isolate grew slowly at 4 °C, was able to grow at 40 °C, required NaCl and grew optimally at pH 6.5–7.0. The G+C content of the genomic DNA was 41.8 mol%. The major fatty acids were summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and summed feature 7 (C18 : 1 ω7c, C18 : 1 ω9t and/or C18 : 1 ω12t). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HJ51T belonged to the genus Pseudoalteromonas and had 91.7–98.9 % 16S rRNA gene sequence similarity with type strains of species of the genus Pseudoalteromonas. Strain HJ51T had 7.2 % DNA–DNA relatedness with Pseudoalteromonas mariniglutinosa DSM 15203T and 12.9 % with Pseudoalteromonas prydzensis DSM 14232T. On the basis of the phenotypic, phylogenetic and genomic data, strain HJ51T represents a novel species of the genus Pseudoalteromonas, for which the name Pseudoalteromonas donghaensis sp. nov. is proposed. The type strain is HJ51T (=KCTC 22219T=LMG 24469T).

A Gram-negative, non-sporulating, non-flagellated rod, designated BR-9T, was isolated from soil collected on the Korean peninsula. Strain BR-9T grew optimally at pH 6.0–7.0, at 30 °C and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BR-9T belonged to the genus Pedobacter and clustered with Pedobacter insulae DS-139T and Pedobacter koreensis WPCB189T. Strain BR-9T exhibited 98.2 and 97.5 % 16S rRNA gene sequence similarity with P. insulae DS-139T and P. koreensis WPCB189T, respectively, and <96.7 % sequence similarity with the type strains of other species in the genus Pedobacter. Strain BR-9T contained MK-7 as the predominant menaquinone and iso-C15 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids. The DNA G+C content of strain BR-9T was 38.5 mol%. DNA–DNA relatedness between strain BR-9T and P. insulae DS-139T and P. koreensis KCTC 12536T was 3.4–4.2 %, which indicated that the isolate was genetically distinct from these type strains. Strain BR-9T was also distinguishable by differences in phenotypic properties. On the basis of the data presented, strain BR-9T is considered to represent a novel species of the genus Pedobacter, for which the name Pedobacter boryungensis sp. nov. is proposed. The type strain is BR-9T ( = KCTC 23344T  = CCUG 60024T).

Two Gram-negative, motile, non-spore-forming and slightly halophilic rods (strains SW-145T and SW-156T) were isolated from sea water of the Yellow Sea in Korea. Strains SW-145T and SW-156T grew optimally at 37 and 30–37 °C, respectively, and in the presence of 2–6 % (w/v) NaCl. Strains SW-145T and SW-156T were chemotaxonomically characterized as having ubiquinone-9 as the predominant respiratory lipoquinone and C16 : 0, C18 : 1 ω9c, C16 : 1 ω9c and C12 : 0 3-OH as the major fatty acids. The DNA G+C contents of strains SW-145T and SW-156T were 58 and 57 mol%, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strains SW-145T and SW-156T fell within the evolutionary radiation enclosed by the genus Marinobacter. The 16S rRNA gene sequences of strains SW-145T and SW-156T were 94·8 % similar. Strains SW-145T and SW-156T exhibited 16S rRNA gene sequence similarity levels of 94·3–98·1 and 95·4–97·7 %, respectively, with respect to the type strains of all Marinobacter species. Levels of DNA–DNA relatedness, together with 16S rRNA gene sequence similarity values, indicated that strains SW-145T and SW-156T are members of two species that are distinct from seven Marinobacter species with validly published names. On the basis of phenotypic properties and phylogenetic and genotypic distinctiveness, strains SW-145T (=KCTC 12185T=DSM 16070T) and SW-156T (=KCTC 12184T=DSM 16072T) should be placed in the genus Marinobacter as the type strains of two distinct novel species, for which the names Marinobacter flavimaris sp. nov. and Marinobacter daepoensis sp. nov. are proposed.

A Gram-staining-negative, non-motile, yellow-pigmented bacterial strain, designated HMD1043T, was isolated from a mesotrophic artificial lake in Korea. The major fatty acids were anteiso-C15 : 0 (28.3 %), iso-C15 : 0 (22.9 %), summed feature 9 (comprising iso-C17 : 1ω9c and/or 10-methyl C16 : 0; 8.8 %) and iso-C13 : 0 (5.3 %). The DNA G+C content was 31.3 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD1043T formed a lineage within the genus Chryseobacterium and was most closely related to Chryseobacterium antarcticum AT1013T (96.8 % 16S rRNA gene sequence similarity) and Chryseobacterium jeonii AT1047T (96.4 %). On the basis of the evidence presented in this study, strain HMD1043T is described as belonging to a novel species of the genus Chryseobacterium, for which the name Chryseobacterium yonginense sp. nov. is proposed. The type strain is HMD1043T ( = KCTC 22744T  = CECT 7547T).

Monophyletic Clade

A strictly anaerobic, mesophilic, endospore-forming bacterium, designated strain HY-35-12T, was isolated from a soil sample in Jeju, Korea. Cells of this isolate were Gram-positive, motile rods that formed oval to spherical terminal spores. Strain HY-35-12T grew optimally at 30 °C, pH 7·0 and 0–0·5 % (w/v) NaCl. The isolate produced pyruvate, lactate, acetate, formate and hydrogen as fermentation end products from glucose. The G+C content of DNA of the isolate was 41 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism formed a monophyletic clade with Clostridium xylanovorans and Clostridium aminovalericum in cluster XIVa of the genus Clostridium. The closest phylogenetic neighbour was C. xylanovorans, with 96·65 % 16S rRNA gene sequence similarity. Several physiological and chemotaxonomic properties were identified that enable strain HY-35-12T to be distinguished from phylogenetically related clostridia. On the basis of polyphasic characteristics, it is proposed that strain HY-35-12T (=IMSNU 40003T=KCTC 5026T=DSM 15929T) represents a novel species, Clostridium jejuense sp. nov.
