Three strains of lactic acid bacteria, designated NJ 317T, NJ 414 and NJ 415, were isolated from the outer leaves of Chinese cabbages (Brassica rapa L. var. glabra Regel) and characterized taxonomically. The strains were Gram-reaction-positive, catalase-negative, facultatively anaerobic cocci that did not produce gas from glucose and formed l-lactic acid. The major fatty acids were C18 : 1ω9c, C16 : 0, C14 : 0 and summed feature 10. Morphological, physiological and phylogenetic data indicated that the strains belonged to the genus Lactococcus. These strains shared similar phenotypic characteristics and exhibited DNA relatedness values >96.6 % to each other, indicating that they represent a single species. The DNA G+C contents of the three strains were 42.1–42.5 mol%. 16S rRNA gene sequences of the novel strains were determined and aligned with those of other species of the genus Lactococcus. On the basis of phylogenetic analysis the three strains grouped with other members of the genus Lactococcus. Lactococcus lactis and Lactococcus garvieae were the most closely related species, sharing a sequence similarity value of 94.4 % with the three strains. Ribotyping patterns, however, revealed that these strains were well-separated from reference strains of species of the genus Lactococcus and DNA–DNA hybridization studies indicated that the novel strains had low levels (<20.2 %) of DNA relatedness with reference strains of L. lactis, L. garvieae and other type strains of previously described species, showing that they represent a different species. Based on this evidence, strains NJ 317T, NJ 414 and NJ 415 represent a novel species of the genus Lactococcus, for which the name Lactococcus fujiensis sp. nov. is proposed. The type strain is NJ 317T ( = JCM16395T  = CGMCC 1.10453T).

A novel actinomycete, designated strain 06182M-1T, was isolated from a mangrove soil sample collected from Chiayi County in Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences revealed levels of similarity of 97.0–98.8 % to the type strains of recognized species of the genus Isoptericola. Chemotaxonomic data also supported the placement of strain 06182M-1T within the genus Isoptericola. However, the low levels of DNA–DNA relatedness between the novel strain and the type strains of recognized species of the genus Isoptericola, in combination with differential phenotypic data, demonstrate that strain 06182M-1T represents a novel species of the genus Isoptericola, for which the name Isoptericola chiayiensis sp. nov. is proposed. The type strain is 06182M-1T ( = BCRC 16888T  = KCTC 19740T).

Three actinomycetes (strains HKI 0478T, HKI 0479 and HKI 0480) isolated from the surfaces of rocks in the Feengrotten medieval alum slate mine (Thuringia, Germany) were examined in a polyphasic taxonomic study. The following morphological and chemotaxonomic features supported their classification as members of the genus Kribbella: the presence of ll-diaminopimelic acid in the cell-wall peptidoglycan; glucose together with minor amounts of mannose and ribose as the whole-cell sugars; polar lipids comprising phosphatidylcholine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown phospho- and glycolipids; fatty acid profiles characterized by the predominance of anteiso-C15 : 0, iso-C16 : 0 and C16 : 0 9-methyl; and the presence of MK-9(H4) as the main menaquinone. The isolates had almost identical 16S rRNA gene sequences (99.9–100 %) and were most closely related to the type strains of Kribbella jejuensis (98.9 % sequence similarity), Kribbella swartbergensis and Kribbella solani (both 98.8 %). A wide range of genotypic and phenotypic markers as well as the low levels of DNA–DNA relatedness between strain HKI 0478T and the type strains of K. jejuensis (41.3 %), K. swartbergensis (18.6 %) and K. solani (14.2 %) distinguished the novel strains from their closest phylogenetic neighbours. On the basis of these results, strain HKI 0478T represents a novel member of the genus Kribbella, for which the name Kribbella aluminosa sp. nov. is proposed. The type strain is HKI 0478T (=DSM 18824T =JCM 14599T).

A polyphasic taxonomic study was undertaken to establish the status of a novel bacterium, designated strain WHSC-8T, which was isolated from soil of Hengshui Lake Wetland Reserve in Hebei province, northern China. Colonies of this strain were yellow and cells were rod-shaped, polar-flagellated and obligately aerobic, exhibiting negative Gram reaction. The strain was able to grow at 0–1 % (w/v) NaCl, pH 5–10 and 20–35 °C, with optimal growth occurring at pH 7.0 and 28 °C without NaCl. Chemotaxonomic data revealed that strain WHSC-8T possesses ubiquinone Q-10 as the predominant respiratory quinone, C18 : 1ω7c, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) as the major fatty acids, and sym-homospermidine as the major polyamine. Sphingomonadaceae-specific sphingoglycolipid was detected in the polar lipid patterns. The G+C content of the genomic DNA was 68.7 mol%. All of the above characters corroborated the assignment of the novel strain to the genus Sphingomonas. Strain WHSC-8T shared less than 97.0 % 16S rRNA gene sequence similarity with the type strains of other species of the genus Sphingomonas, except for Sphingomonas asaccharolytica DSM 10564T (97.5 %). The low DNA–DNA relatedness value and distinct phenotypic and chemotaxonomic characteristics distinguished strain WHSC-8T from closely related species of the genus Sphingomonas. Therefore, strain WHSC-8T represents a novel species of the genus Sphingomonas, for which the name Sphingomonas hengshuiensis sp. nov. is proposed. The type strain is WHSC-8T ( = KCTC 42455T = CCTCC AB 2015265T).

A Gram-stain-negative, aerobic, non-spore-forming bacterial strain, motile by gliding and with rod-shaped or ovoid cells, was isolated from water of an estuary environment at Hwajinpo, South Korea. The strain was designated HJM-19T and subjected to a polyphasic taxonomic study. The novel strain grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain HJM-19T belongs to the genus Gramella. It exhibited 16S rRNA gene sequence similarity values of 97.2–98.1 % to the type strains of Gramella portivictoriae, Gramella aestuariivivens, Gramella marina, Gramella echinicola and Gramella aestuarii, and of 93.9–96.5 % to the type strains of the other species of the genus Gramella with validly published names. Strain HJM-19T contained MK-6 as the predominant menaquinone and anteiso-C15 : 0, anteiso-C17 : 1ω9c and C17 : 0 2-OH as the major fatty acids. The major polar lipids of strain HJM-19T were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain HJM-19T was 48.0 mol%, and its DNA–DNA relatedness values with the type strains of the five phylogenetically closely related species of the genus Gramella were 11–23 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain HJM-19T is separated from other species of the genus Gramella. On the basis of the data presented, strain HJM-19T is considered to represent a novel species of the genus Gramella, for which the name Gramella aquimixticola sp. nov. is proposed. The type strain is HJM-19T ( = KCTC 42706T = NBRC 111224T).

Enrichment cultures inoculated with hydrothermally influenced nearshore sediment from Papua New Guinea led to the isolation of an arsenic-tolerant, acidophilic, facultatively aerobic bacterial strain designated PNG-AprilT. Cells of this strain were Gram-stain-negative, rod-shaped, motile and did not form spores. Strain PNG-AprilT grew at temperatures between 4 °C and 40 °C (optimum 30–37 °C), at pH 3.5 to 8.3 (optimum pH 5–6) and in the presence of up to 2.7 % NaCl (optimum 0–1.0 %). Both arsenate and arsenite were tolerated up to concentrations of at least 0.5 mM. Metabolism in strain PNG-AprilT was strictly respiratory. Heterotrophic growth occurred with O2 or nitrate as electron acceptors, and aerobic lithoautotrophic growth was observed with thiosulfate or nitrite as electron donors. The novel isolate was capable of N2-fixation. The respiratory quinones were Q-8 and Q-7. Phylogenetically, strain PNG-AprilT belongs to the genus Burkholderia and shares the highest 16S rRNA gene sequence similarity with the type strains of Burkholderia fungorum (99.8 %), Burkholderia phytofirmans (98.8 %), Burkholderia caledonica (98.4 %) and Burkholderia sediminicola (98.4 %). Differences from these related species in several physiological characteristics (lipid composition, carbohydrate utilization, enzyme profiles) and DNA–DNA hybridization suggested the isolate represents a novel species of the genus Burkholderia , for which we propose the name Burkholderia insulsa sp. nov. The type strain is PNG-AprilT ( = DSM 28142T = LMG 28183T).

A Gram-negative, motile, rod-shaped, Marinobacter-like bacterial strain, ISL-40T, was isolated from a marine solar saltern of the Yellow Sea in Korea. The taxonomic position of the novel strain was investigated using a polyphasic approach. Strain ISL-40T grew optimally at pH 7.0–8.0 and at 30 °C. It contained Q-9 as the predominant ubiquinone. The major fatty acids were C16 : 0, C16 : 1 ω7c and/or iso-C15 : 0 2-OH and 10-methyl C16 : 0. The DNA G+C content was 58.1 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-40T belongs to the genus Marinobacter. Strain ISL-40T exhibited 16S rRNA gene sequence similarity values of 93.5–96.4 % to the type strains of recognized Marinobacter species. The differential phenotypic properties and phylogenetic distinctiveness of strain ISL-40T revealed that it is separate from recognized Marinobacter species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain ISL-40T represents a novel species of the genus Marinobacter, for which the name Marinobacter salicampi sp. nov. is proposed. The type strain is ISL-40T (=KCTC 12972T=CCUG 54357T).

A novel actinomycete, strain KST3-10T, was isolated from sand sediment of a beach in Jeju, Korea, and was subjected to polyphasic taxonomic characterization. The organism produced circular, smooth, translucent, apricot-coloured colonies comprising coccoid- or rod-shaped cells. Phylogenetic analyses based on 16S rRNA gene sequences showed that the organism belonged to the family Geodermatophilaceae and consistently formed a distinct sub-branch outside the radiation of the genus Blastococcus. The organism showed 16S rRNA gene sequence similarity values of 98.2 % with respect to Blastococcus aggregatus DSM 4725T and 98.1 % with respect to Blastococcus saxobsidens BC444T. The type strains of the two Blastococcus species shared 98.2 % sequence similarity with respect to each other, whereas the levels of sequence similarity between the novel organism and the type strains of the less closely related neighbours, Modestobacter multiseptatus and Geodermatophilus obscurus, were in the range 96.2–96.9 %. The physiological, biochemical and chemotaxonomic data revealed that the novel organism can be readily differentiated from members of the genus Blastococcus and that it merits separate species status. On the basis of the phenotypic and genotypic evidence, strain KST3-10T represents a novel species of the genus Blastococcus, for which the name Blastococcus jejuensis sp. nov. is proposed. The type strain is KST3-10T (=NRRL B-24440T=KCCM 42251T).

Two novel strains of marine lactic acid bacteria, isolated from decaying marine algae collected from a subtropical area of Japan, are described. The isolates, designated O24-2T and O25-2, were Gram-positive, non-sporulating and non-motile. They lacked catalase and quinones. Under anaerobic cultivation conditions, lactate was produced from glucose with the production of formate, acetate and ethanol in a molar ratio of approximately 2 : 1 : 1. Under aerobic cultivation conditions, acetate and lactate were produced from carbohydrates and related compounds. The isolates were slightly halophilic, highly halotolerant and alkaliphilic. They were able to grow in 0–17.0 % (w/v) NaCl, with optimum growth of strains O24-2T and O25-2 at 1.0–3.0 and 1.0–2.0 % (w/v) NaCl, respectively. Growth of strain O24-2T was observed at pH 7.5–9.5, with optimum growth at pH 8.0–8.5. Comparative 16S rRNA gene sequence analysis revealed that the isolates occupied a phylogenetic position within the genus Alkalibacterium, showing highest similarity (99.6 %) to Alkalibacterium putridalgicola T129-2-1T. Although sequence similarity was high, the DNA–DNA relatedness value between strain O24-2T and A. putridalgicola T129-2-1T was 27 %, indicating that they are members of distinct species. The DNA G+C contents of O24-2T and O25-2 were 43.7 and 44.4 mol%, respectively, and DNA–DNA relatedness between the isolates was 89 %. The cell-wall peptidoglycan was type A4β, Orn-d-Asp. The major cellular fatty acid components were C14 : 0, C16 : 0 and C16 : 1ω9c. Based on phenotypic characteristics and genetic distinctiveness, the isolates were classified as representatives of a novel species within the genus Alkalibacterium, for which the name Alkalibacterium subtropicum sp. nov. is proposed; the type strain is O24-2T ( = DSM 23664T = NBRC 107172T).

A novel Gram-stain-positive, white-pigmented, non-motile, non-sporulating, catalase- and oxidase-positive, strictly aerobic coccus, designated strain ZXM223T, was isolated from a seawater sample collected from the coast of Qingdao, PR China, during a green algal bloom. It grew at pH 6.0–10.5 and 0–25.0 % (w/v) NaCl, with optimum growth at pH 8.5 and 3.0 % (w/v) NaCl. Growth occurred at 16–42 °C (optimum at 28 °C). The major fatty acids were anteiso-C15 : 0 and iso-C15 : 0. Menaquinone 6 (MK-6) was the major respiratory quinone. The polar lipids were phosphatidylglycerol, three unidentified phospholipids and two unknown glycolipids. The peptidoglycan type was l-Lys–Gly5–6. The genomic DNA G+C content was 43.5 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed strain ZXM223T within the genus Salinicoccus, with sequence similarity of 92.2–97.1 % between ZXM223T and the type strains of this genus. The closest relatives were Salinicoccus kunmingensis YIM Y15T, ‘S. salitudinis’ YIM-C678 and S. alkaliphilus T8T. The DNA–DNA relatedness between strain ZXM223T and S. kunmingensis CGMCC 1.6302T and ‘S. salitudinis’ CGMCC 1.6299 ( = YIM-C678) was 37±3 and 30±2 %, respectively. The phenotypic, chemotaxonomic and phylogenetic characteristics and low DNA–DNA relatedness support the proposal of a novel species of the genus Salinicoccus, Salinicoccus qingdaonensis sp. nov., with the type strain ZXM223T ( = LMG 24855T  = CGMCC 1.8895T).

Three Gram-positive-staining strains isolated from fermented stinky tofu brine were rod-shaped, non-motile, asporogenous, facultatively anaerobic, heterofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, rpoA and pheS gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus collinoides (98.6 %), Lactobacillus paracollinoides (98.6 %) and Lactobacillus similis (99.6 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 10 %. The phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus odoratitofui sp. nov. is proposed. The type strain is YIT 11304T (=JCM 15043T =BCRC 17810T =DSM 19909T).
