Five strains, JPY461T, JPY359, JPY389, DPU-3 and STM4206 were isolated from nitrogen-fixing nodules on the roots of Mimosa spp. and their taxonomic positions were investigated using a polyphasic approach. All five strains grew at 15–40 °C (optimum, 30–37 °C), at pH 4.0–8.0 (optimum, pH 6.0–7.0) and with 0–1 % (w/v) NaCl [optimum, 0 % (w/v)]. On the basis of 16S rRNA gene sequence analysis, a representative strain (JPY461T) showed 97.2 % sequence similarity to the closest related species Burkholderia acidipaludis SA33T, a similarity of 97.2 % to Burkholderia terrae KMY02T, 97.1 % to Burkholderia phymatum STM815T and 97.1 % to Burkholderia hospita LMG 20598T. The predominant fatty acids of the five novel strains were summed feature 2 (comprising C16 : 1 iso I and/or C14 : 0 3-OH), summed feature 3 (comprising C16 : 1 ω7c and/or C16 : 1 ω6c), C16 : 0 , C16 : 0 3-OH, C17 : 0 cyclo, C18 : 1 ω7c and C19 : 0 cyclo ω8c. The major isoprenoid quinone was Q-8 and the DNA G+C content of the strains was 63.0–65.0 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified aminophospholipid, an unidentified aminolipid and several unidentified phospholipids. The DNA–DNA relatedness of the novel strain with respect to recognized species of the genus Burkholderia was less than 54 %. On the basis of 16S rRNA and recA gene sequence similarities, chemotaxonomic and phenotypic data, the five strains represent a novel species in the genus Burkholderia , for which the name Burkholderia diazotrophica sp. nov. is proposed with the type strain, JPY461T ( = LMG 26031T = BCRC 80259T = KCTC 23308T).

Four strains, designated JPY-345T, JPY-347, JPY-366 and JPY-581, were isolated from nitrogen-fixing nodules on the roots of two species of Mimosa, Mimosa cordistipula and Mimosa misera, that are native to North East Brazil, and their taxonomic positions were investigated by using a polyphasic approach. All four strains grew at 15–43 °C (optimum 35 °C), at pH 4–7 (optimum pH 5) and with 0–2 % (w/v) NaCl (optimum 0 % NaCl). On the basis of 16S rRNA gene sequence analysis, strain JPY-345T showed 97.3 % sequence similarity to the closest related species Burkholderia soli GP25-8T, 97.3 % sequence similarity to Burkholderia caryophylli ATCC25418T and 97.1 % sequence similarity to Burkholderia kururiensis KP23T. The predominant fatty acids of the strains were C18 : 1ω7c (36.1 %), C16 : 0 (19.8 %) and summed feature 3, comprising C16 : 1ω7c and/or C16 : 1ω6c (11.5 %). The major isoprenoid quinone was Q-8 and the DNA G+C content of the strains was 64.2–65.7 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several uncharacterized aminophospholipids and phospholipids. DNA–DNA hybridizations between the novel strain and recognized species of the genus Burkholderia yielded relatedness values of <51.8 %. On the basis of 16S rRNA and recA gene sequence similarities and chemotaxonomic and phenotypic data, the four strains represent a novel species in the genus Burkholderia , for which the name Burkholderia symbiotica sp. nov. is proposed. The type strain is JPY-345T ( = LMG 26032T  = BCRC 80258T  = KCTC 23309T).

A novel Gram-stain-positive bacterium, designated strain YIM M11385T, was isolated from a marine sediment sample collected from the South Bay, Little Andaman Island, India with a salinity of 35 p.p.m., pH 8.5. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM M11385T belongs to the genus Marininema , supported by a bootstrap value of 100 %. The taxonomic position of this organism was further established by using a polyphasic approach. Strain YIM M11385T grew optimally at 28 °C, pH 7.0 and in the presence of 0–5 % (w/v) NaCl. The 16S rRNA gene sequence similarity between strain YIM M11385T and Marininema mesophilum SCSIO 10219T was 98.3 %. Strain YIM M11385T exhibited a quinone system with only MK-7, the polar lipid profile included diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as major components, and the major fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The level of DNA–DNA relatedness between strain YIM M11385T and M. mesophilum SCSIO 10219T was 59.36 %. On the basis of genotypic and phenotypic data, it is apparent that strain YIM M11385T represents a novel species of the genus Marininema , for which the name Marininema halotolerans sp. nov. is proposed. The type strain is YIM M11385T ( = CCTCC AB 2012052T = DSM 45789T). In addition, we propose that the description of the genus Marininema should be further emended based on the results of the present study.

An aerobic, Gram-stain-negative, motile, mesophilic bacterium, designated strain 7515T-07T, was isolated from an air sample in the Taean region, Republic of Korea. The strain grew at 4–40 °C (optimum, 30 °C) and pH 5.0–9.0 (optimum, pH 7.0). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 7515T-07T was related to members of the genus Roseomonas and had highest 16S rRNA gene sequence similarity with Roseomonas ludipueritiae 170/96T (96.7 %). 16S RNA gene sequence similarity between strain 7515T-07T and Roseomonas gilardii ATCC 49956T (the type species of the genus Roseomonas ) was 93.4 %. Strain 7515T-07T contained Q-10 as the ubiquinone and C18 : 1ω7c and C19 : 0 cyclo ω8c as the dominant fatty acids (>10 %). The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and two unidentified aminolipids. The DNA G+C content was 73.0 mol%. Combined data from phenotypic, phylogenetic and chemotaxonomic studies demonstrated that strain 7515T-07T is a representative of a novel species of the genus Roseomonas , for which the name Roseomonas aerophila sp. nov. is proposed. The type strain is 7515T-07T ( = KACC 16529T = NBRC 108923T).

An actinomycete, strain 2602GPT1-05T, was isolated from a composite mangrove soil sample collected from Wenchang, Hainan province, China. Strain 2602GPT1-05T showed closest 16S rRNA gene sequence similarity to Micromonospora haikouensis 232617T (99.05 %), and phylogenetically clustered with Micromonospora haikouensis 232617T, Micromonospora matsumotoense IMSNU 22003T (98.7 %) and Micromonospora rifamycinica AM105T (98.6 %) based on the 16S rRNA and gyrB gene sequence phylogenetic analysis. The strain harboured meso-DAP and glycine as major cell-wall amino acids, and MK-10(H6) and MK-9(H6) as predominant menaquinones. The characteristic whole-cell sugars were xylose, arabinose, glucose and galactose. The polar lipid profile comprised phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylglycerol, phosphatidylinositol mannosides, unknown phospholipid and an unknown phosphoglycolipid. The major cellular fatty acids were C18 : 1ω9c, iso-C15 : 0, 10-methyl C18 : 0 (tuberculostearic acid), C16 : 0, C18 : 0 and iso-C16 : 0. The DNA G+C content was 71.7 mol%. Furthermore, some physiological and biochemical properties and low DNA–DNA relatedness values enabled the strain to be differentiated from members of closely related species. On the basis of these phenotypic, genotypic and chemotaxonomic data, strain 2602GPT1-05T represents a novel species of the genus Micromonospora , for which the name Micromonospora wenchangensis sp. nov. is proposed. The type strain is 2602GPT1-05T ( = CCTCC AA 2012002T = DSM 45709T).

Strains LMG 27428T and LMG 27427 were isolated from the caecal content of a chicken and produced butyric, lactic and formic acids as major metabolic end products. The genomic DNA G+C contents of strains LMG 27428T and LMG 27427 were 40.4 and 38.8 mol%. On the basis of 16S rRNA gene sequence similarity, both strains were most closely related to the generically misclassified Streptococcus pleomorphus ATCC 29734T. Strain LMG 27428T could be distinguished from S. pleomorphus ATCC 29734T based on production of more lactic acid and less formic acid in M2GSC medium, a higher DNA G+C content and the absence of activities of acid phosphatase and leucine, arginine, leucyl glycine, pyroglutamic acid, glycine and histidine arylamidases, while strain LMG 27428 was biochemically indistinguishable from S. pleomorphus ATCC 29734T. The novel genus Faecalicoccus gen. nov. within the family Erysipelotrichaceae is proposed to accommodate strains LMG 27428T and LMG 27427. Strain LMG 27428T ( = DSM 26963T) is the type strain of Faecalicoccus acidiformans sp. nov., and strain LMG 27427 ( = DSM 26962) is a strain of Faecalicoccus pleomorphus comb. nov. (type strain LMG 17756T = ATCC 29734T = DSM 20574T). Furthermore, the nearest phylogenetic neighbours of the genus Faecalicoccus are the generically misclassified Eubacterium cylindroides DSM 3983T (94.4 % 16S rRNA gene sequence similarity to strain LMG 27428T) and Eubacterium biforme DSM 3989T (92.7 % 16S rRNA gene sequence similarity to strain LMG 27428T). We present genotypic and phenotypic data that allow the differentiation of each of these taxa and propose to reclassify these generically misnamed species of the genus Eubacterium formally as Faecalitalea cylindroides gen. nov., comb. nov. and Holdemanella biformis gen. nov., comb. nov., respectively. The type strain of Faecalitalea cylindroides is DSM 3983T = ATCC 27803T = JCM 10261T and that of Holdemanella biformis is DSM 3989T = ATCC 27806T = CCUG 28091T.

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).

A novel bacterium, designated strain JchiT, was isolated from soil in Taiwan and characterized using a polyphasic approach. Cells of strain JchiT were aerobic, Gram-stain-negative, motile and rod-shaped. They contained poly-β-hydroxybutyrate granules and formed dark-yellow colonies. Growth occurred at 20–37 °C (optimum between 25 and 30 °C), at pH 6.0–8.0 (optimum between pH 7.0 and pH 8.0) and with 0–2 % NaCl (optimum between 0 and 1 %). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain JchiT belonged to the genus Jeongeupia and that its closest neighbour was Jeongeupia naejangsanensis BIO-TAS4-2T (98.0 % sequence similarity). The major fatty acids (>10 %) of strain JchiT were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C18 : 1ω7c. The major cellular hydroxy fatty acid was C12 : 0 3-OH. The isoprenoid quinone was Q-8 and the genomic DNA G+C content was 66.1 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylserine and two unidentified phospholipids. The DNA–DNA relatedness value between strain JchiT and J. naejangsanensis BIO-TAS4-2T was about 41.0 %. On the basis of the genotypic and phenotypic data, strain JchiT represents a novel species in the genus Jeongeupia , for which the name Jeongeupia chitinilytica sp. nov. is proposed. The type strain is JchiT ( = BCRC 80367T  = KCTC 23701T).

Strain SB026T was isolated from Brazilian rainforest soil and its taxonomic position established using data from a polyphasic study. The organism showed a combination of chemotaxonomic and morphological features consistent with its classification in the genus Amycolatopsis and formed a branch in the Amycolatopsis 16S rRNA gene tree together with Amycolatopsis bullii NRRL B-24847T, Amycolatopsis plumensis NRRL B-24324T, Amycolatopsis tolypomycina DSM 44544T and Amycolatopsis vancoresmycina NRRL B-24208T. It was related most closely to A. bullii NRRL B-24847T (99.0 % 16S rRNA gene sequence similarity), but was distinguished from this strain by a low level of DNA–DNA relatedness (~46 %) and discriminatory phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the isolate should be classified in the genus Amycolatopsis as representing a novel species, Amycolatopsis rhabdoformis sp. nov. The type strain is SB026T ( = CBMAI 1694T = CMAA 1285T = NCIMB 14900T).

A novel actinomycete, designated strain NEAU-TCZ24T, was isolated from soil and characterized using a polyphasic approach. The results of phylogenetic analysis based on the 16S rRNA gene sequence indicated that the organism should be assigned to the genus Cellulomonas and formed a stable clade with its closest relatives Cellulomonas terrae JCM 14899T (98.4 % 16S rRNA gene sequence similarity), Cellulomonas xylanilytica JCM 14281T (97.9 %) and Cellulomonas humilata JCM 11945T (97.7 %). The major menaquinones were identified as MK-9(H4) and MK-8(H4). The phospholipid profile was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositolmannoside, a ninhydrin-positiveglycolipid, an unidentified phosphoglycolipid, an unidentified phospholipid and an unidentified lipid. The major fatty acids were identified as anteiso-C15 : 0, C18 : 1ω9c, C16 : 0 and anteiso-C17 : 0. Moreover, morphological and chemotaxonomic properties of NEAU-TCZ24T also confirmed the affiliation of the isolate to the genus Cellulomonas . However, multilocus sequence analysis based on five other house-keeping genes (gyrB, rpoB, recA, relA and atpD), DNA–DNA relatedness, physiological and biochemical data indicated that NEAU-TCZ24T could be distinguished from its closest relatives. Therefore, it is proposed that NEAU-TCZ24T represents a novel species of the genus Cellulomonas , for which the name Cellulomonas rhizosphaerae sp. nov. is proposed. The type strain is NEAU-TCZ24T (=CCTCC AA 2018042T=JCM 32383T).

A Gram-stain-positive, aerobic, endospore-forming bacterial strain, isolated from the rhizosphere of Zea mays, was studied for its detailed taxonomic allocation. Based on 16S rRNA gene sequence similarity comparisons, strain JJ-447T was shown to be a member of the genus Paenibacillus , most closely related to the type strain of Paenibacillus solanacearum (97.8 %). The 16S rRNA gene sequence similarity values to all other Paenibacillus species were below 97.0 %. DNA–DNA hybridization (DDH) values with the type strain of P. solanacearum were 35.9 % (reciprocal 27%), respectively. The average nucleotide identity and in silico DDH values with the type strain of P. solanacearum were 84.86 and 28.9 %, respectively. The quinone system of strain JJ-447T consisted exclusively of menaquinones and the major component was MK-7 (96.4 %) but minor amounts of MK–6 (3.6 %) were detected as well. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminolipid. Major fatty acids were iso- and anteiso-branched with the major compounds anteiso-C15 : 0 and iso-C15 : 0. Physiological and biochemical characteristics allowed a further phenotypic differentiation of strain JJ-447T from the most closely related species on the basis of d-glucose, l-arabinose and d-mannose assimilation and other physiological tests. Thus, JJ-447T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus allorhizosphaerae sp. nov. is proposed, with JJ-447T (=LMG 31601T=CCM 9021T=CIP 111802T) as the type strain.
