A Gram-positive, oxidase- and catalase-positive, strictly aerobic and motile bacterium, designated WS 4626T, was isolated from a medical practice. Spherical endospores were formed terminally in swollen rods. The genomic DNA G+C content was 37.1 mol%. Cells contained iso-C15 : 0, anteiso-C15 : 0, iso-C17 : 1ω10c, anteiso-C17 : 0 and iso-C17 : 0 as the predominant cellular fatty acids and MK-7 and MK-6 as the major isoprenoid quinones. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol, the cell-wall peptidoglycan was type A4α, l-Lys-d-Asp and the major cell-wall sugar was xylose. The closest phylogenetic relatives were Lysinibacillus xylanilyticus XDB9T (96.7 % 16S rRNA gene sequence similarity) and Lysinibacillus odysseyi 34hs-1T (96.5 %). DNA–DNA relatedness between the isolate and L. odysseyi DSM 18869T was very low (6 %). On the basis of the data presented, strain WS 4626T represents a novel species of the genus Lysinibacillus , for which the name Lysinibacillus meyeri sp. nov. is proposed. The type strain is WS 4626T ( = DSM 25057T = LMG 26643T).

A Gram-stain-positive, aerobic, motile, rod-shaped bacterium, designated strain Mn1-7T, was isolated from manganese mining soil in Tianjin, China. The closest phylogenetic relatives were Lysinibacillus massiliensis CCUG 49529T (97.2 % 16S rRNA gene sequence similarity), L. xylanilyticus XDB9T (96.7 %), L. sinduriensis JCM 15800T (96.2 %), L. odysseyi NBRC 100172T (95.9 %) and L. boronitolerans NBRC 103108T (95.4 %) (the type species of the genus). DNA–DNA hybridization values for strain Mn1-7T with the type strains of L. massiliensis and L. sinduriensis were 24.9 and 27.7 %, respectively. The genomic DNA G+C content was 38.4 mol%. The major menaquinone was MK-7 and the major fatty acids were iso-C15 : 0, iso-C16 : 0 and iso-C14 : 0. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The cell-wall peptidoglycan was type A4α (l-Lys–d-Asp), and the predominant cell-wall sugar was xylose. DNA–DNA hybridization results and comparison of phenotypic and chemotaxonomic characters between strain Mn1-7T and the phylogenetically most closely related strains revealed that the isolate represents a novel species of the genus Lysinibacillus , for which the name Lysinibacillus manganicus sp. nov. is proposed.

A Gram-stain-negative, strictly aerobic, rod-shaped and pinkish-yellow bacterium, which was motile by gliding and designated strain THG–T11T, was isolated from tomato rhizosphere soil in Gyeonggi province, Republic of Korea. Based on 16S rRNA gene sequence comparisons, strain THG-T11T was found to be most closely related to ‘Pedobacter zeaxanthinifaciens’ TDMA-5 (95.9 % sequence similarity), Pedobacter agri PB92T (94.9 %), Pedobacter rhizosphaerae 01-96T (94.6 %) and Pedobacter alluvionis NWER-II11T (94.5 %). The DNA G+C content was 38.4 mol%. The only isoprenoid quinone detected in strain THG-T11T was menaquinone-7 (MK-7). The major component in the polyamine pattern was sym-homospermidine. The major polar lipids were phosphatidylethanolamine, an unidentified phosphoglycolipid, an unidentified glycolipid, an unidentified lipid, unidentified aminophospholipids and unidentified aminolipids. The major ceramide was found to be ceramide phosphorylethanolamine. The major fatty acids were identified as iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. These data support the affiliation of strain THG-T11T to the genus Pedobacter . Based on phenotypic, chemotaxonomic and phylogenetic analysis, it is proposed that strain THG-T11T represents a novel species of the genus Pedobacter for which the name Pedobacter ureilyticus sp. nov. is proposed, with THG-T11T as the type strain ( = KACC 17660T = JCM 19461T).

Three novel actinomycete strains, designated as DR6-1T, DR6-2 and DR6-4, isolated from the roots of Dendrobium heterocarpum Lindl in Thailand were studied using a polyphasic taxonomic approach. The strains grew at 20–37 °C, at pH 5–10 and with 5 % (w/v) NaCl. They contained meso-diaminopimelic acid in the cell-wall peptidoglycan and MK-9(H4) was a major menaquinone. Arabinose and galactose were the major sugars in the cell wall. The predominant cellular fatty acids were iso-C16 : 0 and iso-C15 : 0. The detected polar lipids were diphosphatidylglycerol, hydroxyphosphatidylethanolamine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. Strains DR6-1T, DR6-2 and DR6-4 shared 99.9–100 % 16S rRNA gene sequence similarity and were closely related to Amycolatopsis echigonensis JCM 21831T (98.7-98.8%). The approximate genome size of strain DR6-1T was 9.6 Mb with a G+C content of 69.6 mol%. The ANIb and dDDH values between genomic sequences of strain DR6-1T and Amycolatopsis echigonensis JCM21831T, Amycolatopsis rubida JCM 10871T and Amycolatopsis nivea KCTC 39515T were 90.55, 92.25, 92.60%, and 47.20, 52.10 and 52.50%, respectively. Based on the phenotypic, chemotaxonomic and genotypic characteristics, it has been concluded that strains DR6-1T, DR6-2 and DR6-4 represent a novel species of the genus Amycolatopsis for which the name Amycolatopsis dendrobii sp. nov. is proposed. The type strain is DR6-1T (=JCM 33742T=KCTC 49546T=TISTR 2840T).

A Gram-stain-negative, strictly aerobic and heterotrophic bacterial strain, designed strain D1T, was isolated from a recirculating mariculture system in Tianjin, China. Its taxonomic position was determined using a polyphasic approach. Cells of strain D1T were non-flagellated short rods, 0.3–0.5 µm wide and 0.5–1.0 µm long. Growth was observed at 15–30 °C (optimum, 25 °C), at pH 5.5–9.0 (optimum, pH 6.5–7.0) and in the presence of 1–8 % (w/v) NaCl (optimum, 2–3 %). Cells contained carotenoid pigments but not flexirubin-type pigments. Strain D1T contained MK-6 as the sole menaquinone and phosphatidylethanolamine (PE) as the sole phospholipid and four unidentified lipids. The major cellular fatty acids (>10 %) were iso-C15 : 0 (23.2 %), iso-C17 : 0 3-OH (15.2 %), C16 : 1ω7c/C16 : 1ω6c (14.3 %), iso-C15 : 0 3-OH (13.5 %) and iso-C15 : 1 G (10.8 %). 16S rRNA gene sequence analyses indicated that strain D1T belonged to the family Flavobacteriaceae and showed closest phylogenetic relationship to the genus Lutibacter , with highest sequence similarity to Lutibacter aestuarii MA-My1T (92.2 %). The DNA G+C content of strain D1T was 35.9 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain D1T was considered to represent a novel species in a new genus of the family Flavobacteriaceae , for which the name Wenyingzhuangia marina gen. nov., sp. nov. is proposed. The type strain of the type species is D1T ( = CGMCC 1.12162T = JCM 18494T).

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-negative, strictly aerobic, rod-shaped, brick red-pigmented bacterium, designated R-22-1 c-1T, was isolated from water from Baiyang Lake, Hebei Province, PR China. The strain was able to grow at 20–30 °C (optimum, 30 °C) and pH 6–7 (optimum, pH 6) in Reasoner’s 2A medium. 16S rRNA gene sequence and phylogenetic analyses of R-22-1 c-1T revealed closest relationships to Rufibacter immobilis MCC P1T (97.8 %), Rufibacter sediminis H-1T (97.9 %) and Rufibacter glacialis MDT1-10-3T (97.0 %), with other species of the genus Rufibacter showing less than 97.0 % sequence similarity. The predominant polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids and three unidentified lipids. The major cellular fatty acids were iso-C15 : 0, C15 : 1  ω6c, C17 : 1  ω6c, anteiso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1  ω7c and/or C16 : 1  ω6c) and summed feature 4 (iso-C17 : 1I and/or anteiso-C17 : 1B). The respiratory quinone was MK-7. The draft genome of R-22-1 c-1T was 5.6 Mbp in size, with a G+C content of 50.2 mol%. The average nucleotide identity and digital DNA–DNA hybridization relatedness values between strain R-22-1 c-1T and related type strains were R. immobilis MCC P1T (77.2 and 21.8 %), R. sediminis H-1T (81.6 and 21.4 %) and R. tibetensis 1351T (78.5 and 22.9 %). Based on these phylogenetic, chemotaxonomic and genotypic results, strain R-22-1 c-1T represents a novel species in the genus Rufibacter , for which the name Rufibacter latericius sp. nov. is proposed. The type strain is R-22-1 c-1T (=CGMCC 1.13570T=KCTC 62781T).

A Gram-stain-negative bacterium, designated strain PF-30T, was isolated from floodwater of a paddy field in South Korea. Strain PF-30T was found to be a strictly aerobic, motile and pink-pigmented rods which can grow at 25–40 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum pH 7.0) and at salinities of 0.5–3.0 % NaCl (optimum 0.5 % NaCl). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain PF-30T belongs to the genus Elioraea , showing highest sequence similarity to Elioraea tepidiphila TU-7T (97.1%) and less than 91.3 % similarity with other members of the family Acetobacteraceae . The average nucleotide identity (ANI) and DNA–DNA relatedness between the strain PF-30T and E. tepidiphila TU-7T yielded an ANI value of 75.1 % and DNA–DNA relatedness of 11.7±0.7 %, respectively. The major fatty acids were identified as C18 : 0 and C18 : 1 ω7c. The predominant respiratory quinone was identified as Q-10. The DNA G+C content was determined to be 69.9 mol%. The strain PF-30T was observed to produce plant-growth-promoting materials such as indole-3-acetic acid (IAA), siderophore and phytase. On the basis of the results from phylogenetic, chemotaxonomic and phenotypic data, we concluded that strain PF-30T represents a novel species of the genus Elioraea , for which the name Elioraea rosea sp. nov. is proposed. The type strain is PF-30T (=KACC 19985T=NBRC 113984T).

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 novel Gram-staining-positive, rod-shaped, motile, strictly aerobic, endospore-forming bacterium, designated WCC 4585T, was isolated from a pharmaceutical production line. The organism grew optimally at 30 °C, at pH 8 and in the presence of 0.5 % (w/v) NaCl. Oval endospores were formed subterminally and terminally in swollen sporangia. The cell-wall diamino acid was meso-diaminopimelic acid (type A1γ) and the genomic DNA G+C content was 38.7 mol%. The major menaquinone was MK-7. The cellular fatty acid profile contained major amounts of iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0, and the cellular phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The isolate was most closely related to Bacillus oceanisediminis H2T, Bacillus infantis SMC 4352-1T, Bacillus firmus NCIMB 9366T, Bacillus circulans ATCC 4513T and Bacillus horneckiae DSM 23495T with which it shared less than 98.0 % 16S rRNA gene sequence similarity. DNA–DNA relatedness values between strain WCC 4585T and five type strains of related species were ≤27 % and sequence similarity values based on groEL sequences were ≤88.7 %. On the basis of the characteristics presented, strain WCC 4585T is proposed to represent a novel species, Bacillus gottheilii sp. nov. The type strain is WCC 4585T( = DSM 23668T = CCUG 59876T = LMG 25856T).

A novel type of freshwater bacterium was isolated from the prealpine mesotrophic Starnberger See (Bavaria, southern Germany). Cells of strain 382T were Gram-negative and rod-shaped, motile and creamy-white. The isolate was strictly aerobic, catalase- and oxidase-positive, and grew at pH values of 6–9 (optimum, pH 7) and temperatures of 10–37 °C (optimum, 28 °C). The genomic G+C content of strain 382T was 64.1 mol%. Based on 16S rRNA gene sequence analyses, strain 382T belongs to the family Sphingomonadaceae and clusters within the genus Sphingomonas . Sphingomonas histidinilytica UM 2T and Sphingomonas wittichii DSM 6014T were the closest relatives, as indicated by the highest 16S rRNA gene sequence similarities (97.1 % and 96.8 %, respectively). Sphingomonas paucimobilis DSM 1098T (the type species of the genus Sphingomonas ) exhibited 95.3 % sequence similarity. This affiliation of strain 382T to the genus Sphingomonas is confirmed by the presence of Q-10 as the major respiratory quinone, two sphingoglycolipids, C14 : 0 2-OH as the major 2-hydroxy fatty acid and sym-homospermidine as the major polyamine. The main cellular fatty acids of strain 382T were C18 : 1ω7c (39 %), C16 : 1ω7c (21 %), C16 : 0 (10 %) and C14 : 0 2-OH (10 %). Based on the phylogenetic distance from other species of the genus Sphingomonas and its unusually high C16 : 1ω7c content, strain 382T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas starnbergensis is proposed. The type strain is 382T ( = DSM 25077T  = LMG 26763T).
