A Gram-positive, aerobic actinomycete, designated strain NEAU 119T, was isolated from the rhizosphere of a fig tree and was characterized using a polyphasic approach. The isolate formed branching, non-fragmenting vegetative hyphae and produced black pigment on yeast extract/malt extract (ISP medium 2). The G+C content of the DNA was 76.6 mol%. The organism had chemotaxonomic characteristics typical of the genus Actinoalloteichus and was closely related to the type strains of Actinoalloteichus cyanogriseus, Actinoalloteichus spitiensis and Actinoalloteichus hymeniacidonis, currently the only three recognized species of the genus Actinoalloteichus, sharing 16S rRNA gene similarities of 96.4, 96.6 and 98.1 %, respectively. However, the results of DNA–DNA hybridization studies demonstrated that the novel strain showed only 46.8 % relatedness with the type strain of A. hymeniacidonis. In addition, a set of phenotypic characteristics also readily distinguished strain NEAU 119T from the type strains of recognized species of the genus Actinoalloteichus. According to the above data, it is proposed that strain NEAU 119T represents a novel species, Actinoalloteichus nanshanensis sp. nov. The type strain of Actinoalloteichus nanshanensis is NEAU 119T ( = CGMCC 4.5714T = NBRC 106685T).

Two strains of gliding, agarolytic bacteria, strains YS10T and YML5, were isolated from coastal seawater off Kamogawa, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel isolates represent a separate lineage within the genus Flammeovirga. DNA–DNA hybridization values between these isolates and the type strains of species of the genus Flammeovirga were significantly lower than those accepted as threshold values for the phylogenetic definition of a species. Furthermore, some of the phenotypic characteristics indicate that the isolates differ from other Flammeovirga species. Based on these differences, it is suggested that the isolates represent a novel species, for which the name Flammeovirga kamogawensis sp. nov. is proposed. The type strain is YS10T (=IAM 15451T=NCIMB 14281T).

Three Lactobacillus-like strains, NB53T, NB446T and NB702, were isolated from traditional fermented food in Thailand. Comparative 16S rRNA gene sequence analysis indicated that these strains belong to the Lactobacillus plantarum group. Phylogenetic analysis based on the dnaK, rpoA, pheS and recA gene sequences indicated that these three strains were distantly related to known species present in the L. plantarum group. DNA–DNA hybridization with closely related strains demonstrated that these strains represented two novel species; the novel strains could be differentiated based on chemotaxonomic and phenotypic characteristics. Therefore, two novel species of the genus Lactobacillus, Lactobacillus plajomi sp. nov. (NB53T) and Lactobacillus modestisalitolerans sp. nov. (NB446T and NB702), are proposed with the type strains NB53T ( = NBRC 107333T = BCC 38054T) and NB446T ( = NBRC 107235T = BCC 38191T), respectively.

A Gram-negative, motile, rod-shaped bacterium (WSF2T) was isolated from coastal seawater of the Boso Peninsula in Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain WSF2T represented a separate lineage within the genus Pseudovibrio. The DNA G+C content of strain WSF2T was 51.7 mol%. DNA–DNA hybridization values between strain WSF2T and the type strains of Pseudovibrio species were significantly lower than those accepted as the phylogenetic definition of a species. Furthermore, some biochemical characteristics indicated that strain WSF2T differed from other Pseudovibrio species. Based on these characteristics, it is proposed that the isolate represents a novel species, Pseudovibrio japonicus sp. nov. The type strain is WSF2T (=IAM 15442T=NCIMB 14279T=KCTC 12861T).

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).

A marine bacterial strain, FR1064T, was isolated from a surface seawater sample collected off Jeju Island, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the Gammaproteobacteria and was related to the genus Glaciecola with 97.6 % sequence similarity to Glaciecola pallidula, its nearest phylogenetic neighbour. DNA–DNA relatedness between strain FR1064T and G. pallidula ACAM 615T was 55 %. Cells of the novel isolate were Gram-negative, aerobic, rod-shaped, motile and halophilic, with an optimum sea salts concentration of 4–7 %. The major fatty acids were straight-chain saturated (C16 : 0), summed feature 3 and monounsaturated fatty acid C18 : 1. The DNA G+C content was 44 mol%. Several phenotypic characteristics differentiated the novel isolate from all previously described members of the genus Glaciecola. The polyphasic data obtained in this study clearly demonstrate that strain FR1064T represents a novel species of the genus Glaciecola. The name Glaciecola nitratireducens sp. nov. is therefore proposed, with strain FR1064T (=KCTC 12276T=JCM 12485T) as the type strain.

Two novel species belonging to the genus Shewanella are described on the basis of a polyphasic taxonomic approach. A total of 40 strains of Gram-negative, psychrotolerant, H2S-producing bacteria were isolated from marine fish (cod and plaice) caught in the Baltic Sea off Denmark. Strains belonging to group 1 (seven strains) were a lactate-assimilating variant of Shewanella morhuae with a G+C content of 44 mol%. The strains of group 2 (33 strains) utilized lactate, N-acetylglucosamine and malate but did not produce DNase or ornithine decarboxylase. Their G+C content was 47 mol%. Phylogenetic analysis of the 16S rRNA gene sequence data placed the two novel species within the genus Shewanella. Group 1 showed greatest sequence similarity with S. morhuae ATCC BAA-1205T (99.9 %). However, gyrB gene sequence analysis and DNA–DNA hybridization differentiated these isolates from S. morhuae, with 95.6 % sequence similarity and less than 57 % DNA relatedness, respectively. Group 2 strains shared more than 99 % 16S rRNA gene sequence similarity with the type strains of Shewanella colwelliana and Shewanella affinis, but gyrB sequence similarity (~85 %) and the results of DNA hybridization (~28 %) indicated that the new isolates represented a novel species. Furthermore, when compared to each other, the type strains of S. colwelliana and S. affinis had almost identical gyrB sequences and significantly high DNA reassociation values (76–83 %), indicating that they belonged to the same species. Based on the conclusions of this study, we propose the novel species Shewanella glacialipiscicola sp. nov. (type strain T147T=LMG 23744T=NBRC 102030T) for group 1 strains and Shewanella algidipiscicola sp. nov. (type strain S13T=LMG 23746T=NBRC 102032T) for group 2 strains, and we propose that Shewanella affinis as a later heterotypic synonym of Shewanella colwelliana.

A novel, psychrotolerant, facultative anaerobe, strain FTR1T, was isolated from Pleistocene ice from the permafrost tunnel in Fox, Alaska. Gram-positive, motile, rod-shaped cells were observed with sizes 0·6–0·7×0·9–1·5 μm. Growth occurred within the pH range 6·5–9·5 with optimum growth at pH 7·3–7·5. The temperature range for growth of the novel isolate was 0–28 °C and optimum growth occurred at 24 °C. The novel isolate does not require NaCl; growth was observed between 0 and 5 % NaCl with optimum growth at 0·5 % (w/v). The novel isolate was a catalase-negative chemoorganoheterotroph that used as substrates sugars and some products of proteolysis. The metabolic end products were acetate, ethanol and CO2. Strain FTR1T was sensitive to ampicillin, tetracycline, chloramphenicol, rifampicin, kanamycin and gentamicin. 16S rRNA gene sequence analysis showed 99·8 % similarity between strain FTR1T and Carnobacterium alterfunditum, but DNA–DNA hybridization between them demonstrated 39±1·5 % relatedness. On the basis of genotypic and phenotypic characteristics, it is proposed that strain FTR1T (=ATCC BAA-754T=JCM 12174T=CIP 108033T) be assigned to the novel species Carnobacterium pleistocenium sp. nov.

Phylogenetic analysis of ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120, based on 16S rRNA gene sequences, revealed that these organisms are related to members of the genus Actinocorallia. These organisms contained glutamic acid, alanine and meso-diaminopimelic acid as cell-wall amino acids and the menaquinones MK-9(H4), MK-9(H6) and MK-9(H8). The chemotaxonomic characteristics of the strains were consistent with those of the genus Actinocorallia. However, DNA–DNA hybridization and phenotypic characteristics revealed that the strains differed from the recognized species of the genus Actinocorallia. Therefore, we propose that ‘Sarraceniospora aurea’ NBRC 14752 and strain NBRC 15120 be reclassified in the genus Actinocorallia as a novel species, Actinocorallia aurea sp. nov. (type strain NBRC 14752T=DSM 44434T).

A rod-shaped, endospore-forming, Gram-reaction-positive bacterium, designated strain WPCB018T, was isolated from a fresh water sample collected from Woopo wetland, Korea. The isolate was identified as a member of the genus Paenibacillus on the basis of phenotypic characteristics and phylogenetic inference based on 16S rRNA gene sequence analysis. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and unknown aminophospholipids. The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid. The predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15 : 0 (32.2 %), C16 : 0 (20.1 %) and C18 : 0 (18.1 %). The DNA G+C content was 56.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain WPCB018T belongs to a cluster comprising species of the genus Paenibacillus, its closest neighbours being Paenibacillus humicus PC-147T (97.5 %) and Paenibcillus pasadenensis SAFN-007T (96.2 %). Genomic DNA–DNA hybridizations performed with strain WPCB018T and type strains of the species P. humicus, P. pinihumi, P. phyllosphaerae, P. pasadenensis and P. tarimensis showed relatedness values of only 10, 17, 18, 19 and 20 %, respectively. On the basis of phenotypic, molecular and genetic evidence, strain WPCB018T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus wooponensis sp. nov. is proposed. The type strain of the novel species is WPCB018T ( = KCTC 13280T  = JCM 16350T).

Three novel Gram-stain-positive bacteria, designated IY07-20T, IY07-56T and IY07-113, were isolated from soil samples from Iriomote Island, Okinawa, Japan, and their taxonomic positions were investigated by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the three isolates were closely related to the members of the genus Agromyces , with similarity range of 95.6–98.7 %. The isolates contained l-2,4-diaminobutylic acid, d-alanine, d-glutamic acid and glycine in their peptidoglycans. The predominant menaquinone was MK-12 and the major fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0. The DNA G+C contents were 70.9–72.9 mol%. The chemotaxonomic characteristics of the isolates matched those described for members of the genus Agromyces . The results of phylogenetic analysis and DNA–DNA hybridization, along with differences in phenotypic characteristics between strains IY07-20T, IY07-56T and IY07-113 and the species of the genus Agromyces with validly published names, indicate that the three isolates merit classification as representatives of two novel species of the genus Agromyces , for which the names Agromyces iriomotensis sp. nov. and Agromyces subtropica sp. nov. are proposed; the type strains are IY07-20T ( = NBRC 106452T = DSM 26155T) and IY07-56T ( = NBRC 106454T = DSM 26153T), respectively.
