Two novel Pediococcus strains, Z-1 and Z-8T, were isolated from a distilled-spirit-fermenting cellar in Hebei Province, China. The cells were Gram-positive, non-spore-forming, non-motile cocci, occurring in pairs or tetrads. The strains were facultatively anaerobic and produced 50 % (−)-d-/50 % (+)-l-lactic acid exclusively from glucose fermentation, but did not produce catalase. Both strains fermented rhamnose, ribose, xylose, lactose, maltose, trehalose and sucrose, and tolerated 10 % ethanol. The mean G+C content of the two strains was 38±1 mol% (37 mol% for the type strain, Z-8T). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Z-8T clustered within the Pediococcus damnosus–Pediococcus inopinatus–Pediococcus parvulus group, with 98·3–98·5 % 16S rRNA gene similarity. DNA–DNA relatedness between strain Z-8T and P. damnosus LMG 11484T, P. inopinatus LMG 11409T and P. parvulus LMG 11486T was 19±4, 35±5 and 31±5 %, respectively. Therefore, based on the distinctive phenotypic characteristics, and genotypic and phylogenetic analyses, a novel Pediococcus species, Pediococcus cellicola sp. nov., is proposed. The type strain is Z-8T (=AS 1.3787T=LMG 22956T).

Pink-pigmented, facultatively methylotrophic bacteria, strains 87eT and 99bT, were isolated from the bryophytes Haplocladium microphyllum and Brachythecium plumosum, respectively. The cells of both strains were Gram-reaction-negative, motile, non-spore-forming rods. On the basis of 16S rRNA gene sequence similarity, strains 87eT and 99bT were found to be related to Methylobacterium organophilum ATCC 27886T (97.1 % and 97.7 %, respectively). Strains 87eT and 99bT showed highest 16S rRNA gene similarity to Methylobacterium gnaphalii 23eT (98.3 and 99.0 %, respectively). The phylogenetic similarities to all other species of the genus Methylobacterium with validly published names were less than 97 %. Major cellular fatty acids of both strains were C18 : 1ω7c and C18 : 0. The results of DNA–DNA hybridization, phylogenetic analyses based on 16S rRNA and cpn60 gene sequences, fatty acid profiles, whole-cell matrix-assisted, laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) analysis, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strains 87eT and 99bT from their phylogenetically closest relatives. We propose that strains 87eT and 99bT represent novel species within the genus Methylobacterium , for which the names Methylobacterium haplocladii sp. nov. (type strain 87eT = DSM 24195T = NBRC 107714T) and Methylobacterium brachythecii sp. nov. (type strain 99bT = DSM 24105T = NBRC 107710T) are proposed.

Four Gram-negative, motile, rod-shaped bacterial strains were isolated from soil samples collected from south-east China. A taxonomic study including phylogenetic analysis based on 16S rRNA gene sequences and phenotypic characteristics was performed. DNA G+C contents of the four strains were 63–66 mol%. Their predominant ubiquinone was Q-8. The fatty acid profiles contained C16 : 1 ω7c (36·9–54·7 %) and C16 : 0 (22·8–25·5 %) as the major components. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and DNA–DNA hybridization results, the four isolates are considered to represent four novel species of the genus Massilia, for which the names Massilia dura sp. nov. (type strain 16T=CCTCC AB 204070T=KCTC 12342T), Massilia albidiflava sp. nov. (type strain 45T=CCTCC AB 204071T=KCTC 12343T), Massilia plicata sp. nov.

A Gram-stain-negative, aerobic, motile, rod-shaped bacterial strain, GSW-M6T, was isolated from seawater of Geoje island, Korea, and was subjected to a polyphasic taxonomic study. Strain GSW-M6T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, strain GSW-M6T clustered with Thalassobius aestuarii, Thalassobius gelatinovorus and Thalassobius mediterraneus. Strain GSW-M6T exhibited 96.2–96.9 % 16S rRNA gene sequence similarity to the type strains of these three Thalassobius species. Strain GSW-M6T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profiles of strain GSW-M6T and the type strains of the three Thalassobius species were similar, with phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified lipid as common major components. The DNA G+C content of strain GSW-M6T was 57 mol%. The mean level of DNA–DNA relatedness between strain GSW-M6T and the type strain of Thalassobius gelatinovorus was 17 %. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, enabled strain GSW-M6T to be differentiated from recognized species of the genus Thalassobius. On the basis of the data presented, strain GSW-M6T is considered to represent a novel species of the genus Thalassobius, for which the name Thalassobius maritimus sp. nov. is proposed. The type strain is GSW-M6T ( = KCTC 23347T  = CCUG 60021T).

A Gram-variable, endospore-forming moderately halophilic rod, strain SF-121, was isolated from a marine solar saltern of the Yellow Sea in Korea. The result of 16S rRNA gene sequence analysis showed that strain SF-121 has highest sequence similarity (99·7 %) with the type strain of Bacillus halodenitrificans. Phylogenetic analyses based on 16S rRNA gene sequences revealed that B. halodenitrificans DSM 10037T and strain SF-121 are more closely related to the genus Virgibacillus than to the genus Bacillus. Strain SF-121 and B. halodenitrificans DSM 10037T exhibited 16S rRNA gene similarity levels of 95·3–97·5 % with the type strains of Virgibacillus species and 94·0 % with the type strain of Bacillus subtilis. DNA–DNA relatedness and phenotypic data indicated that B. halodenitrificans DSM 10037T and strain SF-121 are members of the same species. B. halodenitrificans DSM 10037T and strain SF-121 exhibited DNA–DNA relatedness values of 9–11 % with the type strains of Virgibacillus carmonensis and Virgibacillus marismortui. On the basis of the phenotypic, chemotaxonomic, phylogenetic and genetic data, B. halodenitrificans should be reclassified in the genus Virgibacillus as Virgibacillus halodenitrificans comb. nov.

A Gram-negative, rod-shaped, Brevundimonas-like bacterial strain, KSL-145T, was isolated from an alkaline soil in Korea and subjected to a polyphasic taxonomic investigation. Strain KSL-145T grew optimally at pH 7.5–8.0 and 30 °C without NaCl. It was characterized chemotaxonomically as containing Q-10 as the predominant ubiquinone and C18 : 1 ω7c and C16 : 0 as the major fatty acids. The DNA G+C content was 61.8 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain KSL-145T fell within the radiation of the cluster comprising Brevundimonas species and Mycoplana bullata. The levels of 16S rRNA gene sequence similarity between strain KSL-145T and the type strains of Brevundimonas species and M. bullata ranged from 95.3 to 98.7 %. The mean DNA–DNA relatedness values between strain KSL-145T and the type strains of Brevundimonas diminuta and M. bullata, the closest phylogenetic relatives, were 26 and 15 %, respectively. Strain KSL-145T could be differentiated from Brevundimonas species and M. bullata by differences in several phenotypic characteristics. On the basis of the phenotypic, phylogenetic and genetic data, strain KSL-145T represents a novel species in the genus Brevundimonas, for which the name Brevundimonas terrae sp. nov. is proposed. The type strain is KSL-145T (=KCTC 12481T=JCM 13476T).

Seven unidentified strictly anaerobic, Gram-negative, non-spore-forming bacteria from spoiled beer or the brewery environment were characterized. Based on 16S rRNA gene sequence analyses, all strains were affiliated to the Sporomusa sub-branch of the class ‘Clostridia’. Three of the strains were non-motile cocci, on average 1·5×1·2 μm or 1·2×1·0 μm, occurring mainly singly or in pairs. They shared nearly identical (>99 %) 16S rRNA gene sequences, being most closely related to the species of the Megasphaera–Anaeroglobus group (⩽93·9 % similarity). According to DNA–DNA hybridization results, the coccoid strains represented two genospecies, neither of which was related to any of the recognized Megasphaera species. Several phenotypic characteristics and/or DNA G+C content also differentiated the strains from each other and from their closest relatives. The other four novel strains were motile, slightly curved to helical rods, 0·6−0·8×3−50 μm or more in size. They shared identical 16S rRNA gene sequences and ribofragment patterns. The highest 16S rRNA gene similarity was found between these isolates and Pectinatus cerevisiiphilus ATCC 29359T (95·6 %) and Pectinatus frisingensis ATCC 33332T (93·6 %). The novel strains also differed from recognized Pectinatus species in their sugar utilization, proteolytic activity, catalase activity, antibiotic resistance and temperature tolerance. The results suggest that the bacteria belong to three novel species, for which the names Megasphaera paucivorans sp. nov. (type strain VTT E-032341T=DSM 16981T), Megasphaera sueciensis sp. nov. (type strain VTT E-97791T=DSM 17042T) and Pectinatus haikarae sp. nov. (type strain VTT E-88329T=DSM 16980T) are proposed.

A Gram-stain-negative, non-motile, non-spore-forming bacterial strain, YCS-5T, was isolated from seawater off the southern coast of Korea. Strain YCS-5T grew optimally at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain YCS-5T fell within the clade comprising Kangiella species. Strain YCS-5T exhibited 16S rRNA gene sequence similarity values of 96.6, 95.7 and 97.9 % to the type strains of Kangiella koreensis, Kangiella aquimarina and Kangiella japonica, respectively, and less than 89.8 % to strains of other species used in the phylogenetic analysis. Strain YCS-5T contained Q-8 as the predominant ubiquinone and iso-C17 : 0, iso-C15 : 0, iso-C11 : 0 3-OH and iso-C17 : 1ω9c as the major fatty acids. The polar lipid profile of strain YCS-5T was similar to that of K. koreensis SW-125T, with phosphatidylglycerol and an unidentified aminolipid as major polar lipids. The DNA G+C content was 47 mol%. The mean DNA–DNA relatedness value between strain YCS-5T and K. japonica JCM 16211T was 12 %. Differential phenotypic properties and the phylogenetic and genetic distinctiveness of strain YCS-5T demonstrated that this strain is distinguishable from other Kangiella species. On the basis of the data presented, strain YCS-5T is considered to represent a novel species of the genus Kangiella, for which the name Kangiella geojedonensis sp. nov. is proposed; the type strain is YCS-5T ( = KCTC 23420T = CCUG 60526T).

A Gram-positive, rod- or coccoid-shaped bacterial strain, DS-17T, was isolated from a soil in Dokdo, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain DS-17T grew optimally at around pH 8.0 and 30 °C in the presence of 0.5–1.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain DS-17T belonged to the genus Nocardioides. The chemotaxonomic properties of strain DS-17T were consistent with those of the genus Nocardioides: the cell-wall peptidoglycan type was based on ll-2,6-diaminopimelic acid, MK-8(H4) was the predominant menaquinone and iso-C16 : 0, C17 : 1 ω8c and C17 : 0 were the major fatty acids. The DNA G+C content was 71.5 mol%. Strain DS-17T exhibited 16S rRNA gene sequence similarity values of 94.5–96.9 % to the type strains of recognized Nocardioides species. Strain DS-17T could be distinguished from recognized Nocardioides species by differences in phenotypic characteristics. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DS-17T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides terrigena sp. nov. is proposed. The type strain is DS-17T (=KCTC 19217T=JCM 14582T).

A bacterial strain named IMCC1877T was obtained from surface seawater collected near the coast of Deokjeok island (Yellow Sea), using a standard dilution-plating method. The strain was Gram-negative, chemoheterotrophic and facultatively anaerobic, requiring NaCl, and cells were motile rods with a single polar flagellum. Colonies on marine agar were very small (average diameter 0.1 mm). Based on 16S rRNA gene sequences, the most closely related species to strain IMCC1877T was Marinobacterium stanieri (93.7 % sequence similarity to the type strain). Phylogenetic analyses based on 16S rRNA gene sequences showed that this marine isolate belonged to the order Oceanospirillales and formed an independent phyletic line within the clade forming the genus Marinobacterium. The DNA G+C content of the strain was 60.7 mol% and the predominant constituents of the cellular fatty acids were C18 : 1 ω7c (36.6 %), C16 : 1 ω7c and/or iso-C15 : 0 2-OH (26.7 %) and C16 : 0 (24.3 %). Based on the taxonomic data, only a distant relationship could be established between strain IMCC1877T and other Marinobacterium species; the strain therefore represents a novel species of the genus Marinobacterium, for which the name Marinobacterium litorale sp. nov. is proposed. The type strain is IMCC1877T (=KCTC 12756T=LMG 23872T).

The 16S Rrna Gene

Two novel bacterial strains, designated Kc1T and Kc5T, were isolated from soil in Japan. Cells of the novel strains were Gram-reaction-positive, aerobic or facultatively anaerobic, motile rods. Phylogenetic analyses based on 16S rRNA gene sequences indicated that both strains belonged to the genus Cellulomonas . The 16S rRNA gene sequences of strains Kc1T and Kc5T showed closest similarity to that of Cellulomonas terrae DB5T (98.1 % and 98.4 % similarity, respectively), and the 16S rRNA gene similarity between the two novel strains was 97.8 %. In both strains, the major menaquinone was MK-9(H4), the predominant polar lipids were diphosphatidylglycerol and phosphatidylinositol mannosides, and the peptidoglycan contained ornithine and glutamic acid. Cell-wall sugars were identified as rhamnose, galactose and mannose in strain Kc1T and rhamnose and glucose in strain Kc5T. The DNA G+C contents of strains Kc1T and Kc5T were 73.6 mol% and 75.8 mol%, respectively. Based on the chemotaxonomic and physiological data and the results of DNA–DNA hybridizations, the two strains represent two novel species within the genus Cellulomonas , for which the names Cellulomonas soli sp. nov. (type strain Kc1T  = DSM 24484T  = JCM 17535T) and Cellulomonas oligotrophica sp. nov. (type strain Kc5T = DSM 24482T = JCM 17534T) are proposed.
