Three strains, KV-810T, KV-811 and KV-816, were isolated from mangrove soil from a southern island in Japan on media supplemented with ascorbic acid or rutin. These strains contained l-ornithine as the diagnostic diamino acid in the cell-wall peptidoglycan and DMK-9(H4) as the predominant menaquinone. The G+C content of the DNA was 70–72 mol%. These characteristics in combination with 16S rRNA gene sequence analysis revealed that the novel strains belonged to the genus Demequina. The DNA–DNA hybridization values showed that the three new strains belonged to the same species, a novel species of the genus Demequina. Therefore strains KV-810T, KV-811 and KV-816 are proposed as representing a novel species, Demequina salsinemoris sp. nov. The type strain is KV-810T (=DSM 22060T=NBRC 105323T).

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.

A Gram-negative, rod-shaped, non-spore-forming bacterium, strain GH9-3T, isolated from greenhouse soil, was investigated in a polyphasic study. The novel organism grew at 10–35 °C, 0–3 % NaCl and pH 5–9. It had ubiquinone 8 (Q-8) as the predominant isoprenoid quinone and possessed C16 : 0, summed feature 3, C17 : 0 cyclo and C18 : 1 ω7c as the major fatty acids (together representing 87.4 % of the total). The DNA G+C content was 67.1 mol%. 16S rRNA gene sequence analysis of strain GH9-3T showed that it grouped within the Variovorax cluster, with highest sequence similarities to Variovorax paradoxus IAM 12373T (98.3 %) and Variovorax dokdonensis DS-43T (98.0 %). DNA–DNA hybridization values between strain GH9-3T and V. paradoxus DSM 30034T and V. dokdonensis DS-43T were 38 and 29 %, respectively. Based on phenotypic, chemotaxonomic and phylogenetic features, it is proposed that strain GH9-3T represents a novel species of the genus Variovorax with the name Variovorax soli sp. nov. The type strain is GH9-3T (=KACC 11579T=DSM 18216T).

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).

Comparative 16S rRNA gene sequence analysis indicates that two distinct sublineages exist within the genus Alcaligenes: the Alcaligenes faecalis lineage, comprising Alcaligenes aquatilis and A. faecalis (with the three subspecies A. faecalis subsp. faecalis, A. faecalis subsp. parafaecalis and A. faecalis subsp. phenolicus), and the Alcaligenes defragrans lineage, comprising A. defragrans. This phylogenetic discrimination is supported by phenotypic and chemotaxonomic differences. It is proposed that the A. defragrans lineage constitutes a distinct genus, for which the name Castellaniella gen. nov. is proposed. The type strain for Castellaniella defragrans gen. nov., comb. nov. is 54PinT (=CCUG 39790T=CIP 105602T=DSM 12141T). Finally, on the basis of data from the literature and new DNA–DNA hybridization and phenotypic data, the novel species Castellaniella denitrificans sp. nov. (type strain NKNTAUT=DSM 11046T=CCUG 39541T) is proposed for two strains previously identified as strains of A. defragrans.

Three Gram-positive, aerobic, non-motile, mesophilic strains, designated 2-25(1)T, 2-29(17)T and 2-70(23)T, were isolated from sandy soil from Chokoria, Cox's Bazar, Bangladesh. The organisms produce short chains of non-motile spores that emerge singly or in tufts from vegetative hyphae on the surface of agar media. A comparative phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolates formed a distinct clade within the evolutionary radiation of the family Micromonosporaceae and clustered with members of the genus Catellatospora. The nearest neighbours were Catellatospora citrea subsp. citrea and C. citrea subsp. methionotrophica. Chemotaxonomic data, such as the presence of meso- and 3-hydroxy-diaminopimelic acids, N-glycolyl type muramic acid, arabinose and xylose and glucose in whole-cell hydrolysates, phosphatidylethanolamine as a diagnostic phospholipid, a tetrahydrogenated menaquinone with 9 isoprene units as a major menaquinone and fatty acid profiles predominated by iso-branched hexadecanoic acid and iso-branched pentadecanoic acid, supported the affiliation of the novel isolates to the genus Catellatospora. The results of DNA–DNA hybridization and physiological and biochemical tests allowed the novel isolates to be differentiated genotypically and phenotypically from the three recognized Catellatospora species. The three isolates therefore represent novel species for which the names Catellatospora chokoriensis sp. nov. [type strain 2-25(1)T=JCM 12950T=DSM 44900T], Catellatospora coxensis sp. nov. [type strain 2-29(17)T=JCM 12951T=DSM 44901T] and Catellatospora bangladeshensis sp. nov. [type strain 2-70(23)T=JCM 12949T=DSM 44899T], are proposed. DNA–DNA hybridization tests with C. citrea subsp. citrea and C. citrea subsp. methionotrophica, in combination with chemotaxonomic and physiological data, demonstrated that C. citrea subsp. methionotrophica should be elevated to a separate species for which the name Catellatospora methionotrophica sp. nov., comb. nov. is proposed (type strain JCM 7543T=DSM 44098T).

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.

Abstract The moderately halophilic, Gram-stain-positive, spore-forming rods, designated SKP4-8T and SKP8-2T isolated from a traditional fermented shrimp paste (Ka-pi), were taxonomic studied based on polyphasic approach. Strain SKP4-8T grew at pH 6.0-9.0 (optimum 7.0), at 25-45°C (optimum 37°C) and in 1-16 % (w/v) NaCl (optimum 5-10). Strain SKP8-2T grew at pH 6.0-9.0 (optimum 8.0), at 25-45°C (optimum 37°C) and in 0-20 % (w/v) NaCl (optimum 3-10 %). The strains contained meso-diaminopimelic acid in cell-wall peptidoglycan and the major menaquinone was MK-7. Strain SKP4-8T contained iso-C15:0, antesio-C15:0 and iso-C17:0; and strain SKP8-2T contained antesio-C15:0, iso-C15:0, iso-C16:0 and antesio-C17:0 as major cellular fatty acids.Phosphatidylglycerol, diphosphatidylglycerol, unknown phospholipids and an unknown glycolipid were detected as major polar lipids. On the basis of 16S rRNA gene sequence analysis, strains SKP4-8T and SKP8-2T belonged to the genus Allobacillus and was closely related to Allobacillus halotolerans LMG 24826T with 98.8 % and 99.3 % similarity, respectively. The comparative genome analysis based on average nucleotide identity (ANI) and digital DNA-DNA hybridization revealed that both strains showed the values below 95 and 70 %, from each other and the Allobacillus halotolerans LMG 24826T, respectively. Based on data from this polyphasic study, strains SKP4-8T and SKP8-2T represent the novel species of the genus Allobacillus and the name Allobacillus salarius sp. nov. was proposed for SKP4-8T (=KCTC 33905T =LMG 30016T =TISTR 2499T); and Allobacillus saliphilus sp. nov. for SKP8-2T (=KCTC 33906T =LMG 29682T =TISTR 2558T).

A novel bacterium, designated TRM 415T, belonging to the genus Brevibacterium, was isolated from a sediment sample from a salt lake in Xinjiang province, China. Comparative 16S rRNA gene sequence analysis indicated that strain TRM 415T was phylogenetically most closely related to Brevibacterium album YIM 90718T (98.4 % sequence similarity) and had low similarity (<95.5 %) to other species of the genus Brevibacterium; however, DNA–DNA hybridization studies between strain TRM 415T and B. album YIM 90718T showed only 41.3 % relatedness. Strain TRM 415T possessed meso-diaminopimelic acid as the diagnostic cell-wall diamino acid, MK-8(H2) as the major menaquinone and polar lipids including phosphatidylglycerol and diphosphatidylglycerol. The major fatty acids were anteiso-C17 : 0 and anteiso-C15 : 0. The genomic DNA G+C content was 69 mol%. Based on the evidence from this polyphasic study, strain TRM 415T represents a novel species of the genus Brevibacterium, for which the name Brevibacterium salitolerans sp. nov. is proposed. The type strain is TRM 415T (=JCM 15900T =CCTCC AB 208328T =KCTC 19616T).

An aerobic, Gram-stain-positive actinomycete, designated strain 3SM4-07T, was characterized using a polyphasic taxonomic approach. The strain produced branching mycelium which fragmented into short or elongated rods. The whole-cell hydrolysates contained ll-2,6-diaminopimelic acid as the diagnostic diamino acid, with glucose and ribose as the main sugars. The predominant cellular fatty acids were anteiso-C15  :  0, iso-C15  :  0 and iso-C16  :  0.The predominant menaquinone was MK-9(H4). Phospholipids consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. Mycolic acids were absent. The DNA G+C content was 72.3 mol%. Strain 3SM4-07T formed a phylogenetic line within the genus Jiangella and its 16S rRNA gene sequence was related most closely to Jiangella alkaliphila D8-87T (99.0 % similarity), Jiangella muralis 15-Je-017T (98.8 %), Jiangella alba YIM 61503T (98.6 %) and Jiangella gansuensis YIM 002T (98.6 %). However, mean DNA–DNA hybridization values revealed that strain 3SM4-07T differed from the closest species previously described in this genus. Data from phenotypic, chemotaxonomic and molecular analyses between strain 3SM4-07T and recognized species of the genus Jiangella indicate that strain 3SM4-07T is a representative of a novel species of the genus Jiangella, for which the name Jiangella mangrovi sp. nov. is proposed. The type strain is 3SM4-07T ( = BCC 60398T = NBRC 109648T).

A novel bacterial strain, designated THG-PC7T, was isolated from fallow farmland soil in Yongin, South Korea. Cells of strain THG-PC7T were Gram-stain-negative, dark yellow, aerobic, rod-shaped and had gliding motility. Strain THG-PC7T grew optimally at 25–35 °C, at pH 7 and in the absence of NaCl. Comparative 16S rRNA gene sequence analysis identified strain THG-PC7T as belonging to the genus Lysobacter, exhibiting highest sequence similarity with Lysobacter ximonensis KCTC 22336T (98.7 %) followed by Lysobacter niastensis KACC 11588T (95.7 %). In DNA–DNA hybridization tests, DNA relatedness between strain THG-PC7T and its closest phylogenetic neighbour L. ximonensis was below 25 %. The DNA G+C content of the novel isolate was determined to be 62.5 mol%. Flexirubin-type pigments were found to be present. The major cellular fatty acids were determined to be iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and iso-C17 : 1ω9c. The major respiratory quinone was identified as ubiquonone-8 (Q8). The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminophospolipid. On the basis of results from DNA–DNA hybridization and the polyphasic data, strain THG-PC7T represents a novel species of the genus Lysobacter, for which the name Lysobacter novalis sp. nov. is proposed. The type strain is THG-PC7T( = KACC 18276T = CCTCC AB 2014319T).
