A Gram-stain-positive, facultatively anaerobic, spore-forming, motile with unipolar biflagella, rod-shaped, indole acetic acid-producing bacterium, named LD4P30T, was isolated from a root of Suaeda salsa collected in Inner Mongolia, northern China. Strain LD4P30T grew at pH 6.0–11.0 (optimum, pH 7.0), 10–40 °C (35 °C) and in the presence of 1–15% (w/v) NaCl (5%). The strain was positive for oxidase and negative for catalase. The major cellular fatty acids of strain LD4P30T were iso-C15:0, C15:1 ω5c and anteiso-C15:0; the major polar lipids were diphosphatidylglycerol and phosphatidylglycerol; and menaquinone-7 was the only respiratory quinone. The genomic DNA G+C content was 36.7 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain LD4P30T clustered with Gracilibacillus thailandensis TP2-8T, Gracilibacillus saliphilus YIM 91119T and Gracilibacillus lacisalsi BH312T, and showed 99.0, 98.9, 98.0 and <97.7% 16S rRNA gene similarity to G. thailandensis TP2-8T, G. saliphilus YIM 91119T, G. lacisalsi BH312T and all other current type strains, respectively. The digital DNA–DNA hybridization and average nucleotide identity based on blast values between strain LD4P30T and G. saliphilus YIM 91119T, G. thailandensis TP2-8T and G. lacisalsi BH312T were 44.9, 44.7 and 44.4%, and 91.1, 91.0 and 90.8%, respectively. Based on its phenotypic, physiological and phylogenetic characteristics, strain LD4P30T represents a novel species, for which the name Gracilibacillus suaedae is proposed. The type strain is LD4P30T (=CGMCC 1.17697T=KCTC 82375T).

Maize Field

A novel isolated yellow-pigmented bacterial designated strain UDD2T was isolated from a maize field soil sample collected in Ilsan, Republic of Korea. Cells of strain UDD2T were Gram-stain-negative, non-sporulating, long rod-shaped and exhibited flagellar motility. Cells could grow at 15–42 °C and pH 5.5–11.0. Strain UDD2T was sensitive to NaCl and barely tolerated up to 1 % NaCl (w/v). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain UDD2T formed a separate clade with the members of genus Sphingosinicella within the family Sphingomonadaceae . Strain UDD2T showed the highest 16S rRNA gene sequence similarity to Sphingosinicella vermicomposti KCTC 224446T (98.5 %) and Sphingosinicella humi KCTC 62519T (96.7 %), followed by members of the genus Sphingomonas (96.4–94.5 %) and Sphingobium (96.1–94.9 %), but they were located in other phylogenetic clusters. Average nucleotide identity and digital DNA–DNA hybridization values between strain UDD2T and S. vermicomposti KCTC 224446T and S. humi KCTC 62519T were 80.2/24.2 and 75.6/20.4 %, respectively. The total size of the genome was 2 421 697 bp and composed of one circular chromosome, with a G+C content of 63.7 mol%. Strain UDD2T produced indole acetic acid (IAA) in the presence of l-tryptophan. Bacterial IAA is a crucial phytohormone in plant growth and development. Gene clusters for indole-3-glycerol phosphate synthase and tryptophan synthase were found in the genome of strain UDD2T. To the best of our knowledge, no member of the genus Sphingosinicella has been reported to produce IAA to date. The major cellular fatty acids (>10 %) were found to be C16 : 0, C14 : 0 2OH and summed feature 3 (comprising C16  : 1 ω7c and/or iso-C15  :  0 2-OH). Strain UDD2T had ubiquinone Q-10 as the major respiratory quinone and homospermidine as the major polyamine. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid, phosphatidylglycerol, phosphatidylcholine, three unidentified phosphoglycolipids, one unidentified phospholipid, one unidentified aminoglycophospholipid, one unidentified glycolipid and one unidentified polar lipid. Based on the phylogenetic, phenotypic, chemotaxonomic and genotypic data, strain UDD2T represents a novel species of the genus Sphingosinicella , for which the name Sphingosinicella flava is proposed. The type strain is UDD2T (=KCTC 82357T=NBRC 114507T).

A Gram-stain-positive, strictly aerobic, motile, endospore-forming, milk-white, indole acetic acid-producing, rod-shaped bacterial strain, designated as HU2P27T, was isolated from a shoot of Kalidium cuspidatum collected in Tumd Right Banner, Inner Mongolia, PR China. Strain grew at 10–40 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0) and with 0–14.0 % NaCl (optimum, 5.0–8.0 %). The strain tested positive for oxidase, catalase and nitrate reductase. The phylogenetic trees based on the 16S rRNA gene sequence and the core genome both showed that strain HU2P27T clustered with Aquibacillus koreensis BH30097T, sharing 97.7 % and <97.0 % of 16S rRNA gene similarity with A. koreensis BH30097T and any other type strain. Strain HU2P27T contained MK-7 as the major respiratory quinone. Its major fatty acids were anteiso-C15 : 0 and iso-C15 : 0, and the major polar lipids were phosphatidylglycerol, diphosphatidylglycerol and four unidentified phospholipids. The genomic DNA G+C content was 36.0 mol%. The average nucleotide identity, amino acid identity and digital DNA–DNA hybridization values of strain HU2P27T with A. koreensis BH30097T were 71.7, 69.2 and 19.4%, respectively. The phylogenetic, physiological and phenotypic results allowed the discrimination of strain HU2P27T from its phylogenetic relatives. The name Aquibacillus kalidii sp. nov. is therefore proposed. The type strain is strain HU2P27T (=CGMCC 1.18646T=KCTC 43248T). Based on the results of 16S rRNA gene and genome analyses, we propose the reclassification of Virgibacillus campisalis Lee et al. 2012 as a later heterotypic synonym of Virgibacillus alimentarius Kim et al. 2011.

Pink-pigmented, facultatively methylotrophic bacteria, strains 87eT and 99bT, were isolated from the bryophytes Haplocladium microphyllum and Brachythecium plumosum, respectively. The cells of both strains were Gram-reaction-negative, motile, non-spore-forming rods. On the basis of 16S rRNA gene sequence similarity, strains 87eT and 99bT were found to be related to Methylobacterium organophilum ATCC 27886T (97.1 % and 97.7 %, respectively). Strains 87eT and 99bT showed highest 16S rRNA gene similarity to Methylobacterium gnaphalii 23eT (98.3 and 99.0 %, respectively). The phylogenetic similarities to all other species of the genus Methylobacterium with validly published names were less than 97 %. Major cellular fatty acids of both strains were C18 : 1ω7c and C18 : 0. The results of DNA–DNA hybridization, phylogenetic analyses based on 16S rRNA and cpn60 gene sequences, fatty acid profiles, whole-cell matrix-assisted, laser-desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) analysis, and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strains 87eT and 99bT from their phylogenetically closest relatives. We propose that strains 87eT and 99bT represent novel species within the genus Methylobacterium , for which the names Methylobacterium haplocladii sp. nov. (type strain 87eT = DSM 24195T = NBRC 107714T) and Methylobacterium brachythecii sp. nov. (type strain 99bT = DSM 24105T = NBRC 107710T) are proposed.

A Gram-stain-negative, non-spore-forming, aerobic, motile, curved rod-shaped bacterium, designed strain R148T was isolated from a coralline algae Tricleocarpa sp. collected from Weizhou island, PR China. The optimal growth of R148T occurred at 25 °C, pH 8–9 in the presence of 0.5 % (w/v) NaCl on the basis of amended marine broth 2216. The genomic DNA G+C content was 59.5 mol%. The only detected respiratory quinone was Q-10. The major polar lipids were phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, and three unidentified ninhydrin-positive lipids. The major cellular fatty acids were C18 : 1ω7c, C16 : 1ω7c, C19 : 0cyclo 9, 10 DMA and C18 : 0. The results of 16S rRNA gene-based global alignment indicated that the closest neighbour of strain R148T was Pelagibius litoralis DSM 21314T (93.1 % similarity), the second is Limibacillus halophilus KCTC 42420T (92.2 %). The results of phylogenetic analysis indicated that R148T forms a distinct branch in the robust clade of R148T and P. litoralis DSM 21314T, while the taxonomic position of this clade in the family Rhodospirillaceae is ambiguous among phylogenetic approaches. The low 16S rRNA gene similarity and distinct polar lipid and cellular fatty acid profile could readily distinguish R148T from closely related type strains. So R148T is suggested to represent a novel species in a novel genus, for which the name Denitrobaculum tricleocarpae gen. nov., sp. nov. is proposed. The type strain is R148T (=MCCC 1K03781T=KCTC 72137T).

Two Gram-stain-positive, catalase-positive and oxidase-negative, aerobic, non-motile, cellobiose-utilizing, short-rod-shaped strains (Z28T and Z29) were isolated from faeces of Tibetan antelope (Pantholops hodgsonii) collected on the Qinghai–Tibet Plateau. Strain Z28T shared 98.1, 98.0, 97.8 and 97.4 % 16S rRNA gene similarity, 24.1, 22.8, 23.2 and 26.3 % digital DNA–DNA hybridization relatedness and 80.8, 80.0, 80.7 and 80.9 % average nucleotide identity values with Cellulomonas oligotrophica DSM 24482T, Cellulomonas flavigena DSM 20109T, Cellulomonas iranensis DSM 14785T and Cellulomonas terrae JCM 14899T, respectively. Results from further phylogenetic analyses based on the 16S rRNA gene and 148 core genes indicated that strains Z28T and Z29 were closest to C. oligotrophica DSM 24482T and C. flavigena DSM 20109T, but clearly separated from the currently recognized species of the genus Cellulomonas . The genomic DNA G+C content of strain Z28T was 75.3 mol%. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C15 : 1 A, C16 : 0 and anteiso-C17 : 0. Ribose and mannose were detected as the whole-cell sugars. The major respiratory quinone was MK-9(H4) and ornithine was the diamino acid of the cell wall. The polar lipids present in strain Z28T were phosphatidylethanolamine, five phospholipids, two aminophospholipids, aminolipid and three unidentified lipids. Comparison of phenotypic and phylogenetic features between the two strains and the related organisms revealed that Z28T and Z29 represent a novel species of the genus Cellulomonas , for which the name Cellulomonas shaoxiangyii sp. nov. is proposed. The type strain is Z28T (=CGMCC 1.16477T=DSM 106200T).

A strictly aerobic, Gram-stain-negative, non-motile, ovoid- and rod-shaped bacterium, designated strain GH1-50T, was isolated from a tidal mudflat sample collected from Dongmak seashore on Gangwha Island, Republic of Korea. The organism showed growth at 20–40 °C (optimum, 30 °C), pH 7–8 (optimum, pH 7) and 2–6  % (w/v) NaCl (optimum, 5 %). The pufLM genes were present but bacteriochlorophyll a was not detected. The major isoprenoid quinone was Q-10. The polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol, an unidentified aminolipid and five unidentified lipids. The predominant cellular fatty acids were C18 : 1  ω7c, C18 : 1  ω7c 11-methyl and C18 : 0. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that the isolate belonged to the family Rhodobacteraceae and was loosely associated with members of the recognized genera. The closest relative was the type strain of Pseudoruegeria marinistellae (96.8 % similarity) followed by Boseongicola aestuarii (96.4 %). Other members of the family shared 16S rRNA gene similarity values below 96.0 % to the novel isolate. The DNA G+C content calculated from the draft genome sequence was 64.0 %. The average amino acid identity, average nucleotide identity and digital DNA–DNA hybridization values between genome sequences of strain GH1-50T and all the type strains of the recognized taxa compared were <70.0, <84.1 and <20.5 %, respectively. Based on data obtained by a polyphasic approach, strain GH1-50T (=KCTC 72224T=NBRC 113929T) represents a novel species of a new genus in the family Rhodobacteraceae , for which the name Kangsaoukella pontilimi gen. nov., sp. nov. is proposed.

Six novel facultatively anaerobic, Gram-stain-positive, rod-shaped, non-haemolytic bacteria (zg-320T/zg-336, zg-917T/zg-910 and zg-913T/zg-915) isolated from animal tissues and human faeces were found to belong to the genus Corynebacterium based on the phylogenetic analyses of 16S rRNA gene and 262 core genes set. Based on the greatest degree of 16S rRNA similarity, zg-320T/zg-336 had the highest 16S rRNA gene similarity to Corynebacterium falsenii DSM 44353T (97.51 %), zg-917T/zg-910 to Corynebacterium coyleae DSM 44184T (98.68 %), and zg-913T/zg-915 to Corynebacterium afermentans subsp. lipophilum CIP 103500T (98.79 %). The three novel type strains had a relatively high DNA G+C content (61.2–64.4 mol%), low DNA relatedness and ANI values with their respective neighbours: 23.5/72.7 %, 25.0/72.3%and 22.6/73.1 % (zg-320T vs. Corynebacterium auriscanis CIP 106629T, Corynebacterium resistens DSM 45100T and Corynebacterium suicordis DSM 45110T); 24.4/82.3% and 23.7/81.3 % (zg-917T vs. C. coyleae DSM 44184T and Corynebacterium jeddahense JCBT); 26.8/83.7% and 27.7/84.4 % (zg-913T vs. Corynebacterium mucifaciens ATCC 700355T and C. afermentans subsp. lipophilum CCUG 32105T). The three novel species had C16 : 0, C18 : 0, C18 : 1  ω9c and C18 : 0 ante/C18 : 2  ω6,9c as the major cellular fatty acids; MK-8(H2) in strain zg-917T and MK-9(H2) in strains zg-320T and zg-913T were found to be the major respiratory quinones. For the three novel species, the detected major polar lipids included diphosphatidylglycerol, phosphatidyl inositol mannoside, phosphatidylglycerol and phosphatidylinositol, the cell-wall peptidoglycan was based on meso-DAP, and the whole-cell sugars mainly included ribose, arabinose and galactose. The three novel species grew optimally at 35–37 °C, 0.5 % (w/v) NaCl and pH 7.0–8.0; notably, they were tolerant of 10.5 % (w/v) NaCl. Based on the results of these comprehensive analyses, three novel species in the genus Corynebacterium are proposed, aptly named Corynebacterium zhongnanshanii sp. nov. (zg-320T = GDMCC 1.1719T = JCM 34106T), Corynebacterium lujinxingii sp. nov. (zg-917T = GDMCC 1.1707T = JCM 34094T) and Corynebacterium wankanglinii sp. nov. (zg-913T = GDMCC 1.1706T = JCM 34398T).

A novel growth-promoting and indole acetic acid-producing strain, designated NEAU-LLBT, was isolated from cow dung collected from Shangzhi, Heilongjiang Province, PR China. Cells of strain NEAU-LLBT were Gram-stain-positive, non-motile, aerobic and non-spore-forming. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain NEAU-LLBT belonged to the genus Microbacterium . Strain NEAU-LLBT had high 16S rRNA sequence similarities of 98.81 and 98.41 % to Microbacterium paludicola DSM 16915T and Microbacterium marinilacus DSM 18904T, and less than 98 % to other members of the genus Microbacterium . Chemotaxonomic characteristics showed that MK-11 and MK-12 were detected as the predominant menaquinones. The peptidoglycan contained glutamic acid, aspartic acid, glycine, ornithine and a small amount of alanine, with ornithine as the diagnostic diamino acid. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. The major fatty acids were identified as anteiso-C15 : 0, iso-C16 : 0 and iso-C17 : 0. The genomic DNA G+C content of strain NEAU-LLBT was 70.2 mol%. In addition, the average nucleotide identity values between strain NEAU-LLBT and its reference strains, M. paludicola DSM 16915T, M. marinilacus DSM 18904T and M. album SYSU D8007T, were found to be 81.1, 79.4 and 78.7 %, respectively, and the level of digital DNA–DNA hybridization between them were 23.8, 22.6 and 21.8 %, respectively. Based on the phenotypic, phylogenetic and genotypic data, strain NEAU-LLBT is considered to represent a novel species of the genus Microbacterium , for which the name Microbacterium stercoris sp. nov is proposed, with NEAU-LLBT (=CCTCC AA 2018028T=JCM 32660T) as the type strain.

Two pairs of aerobic, Gram-stain-positive, rod-shaped strains (HY164T/HY044, HY168T/HY211) were isolated from bat faecal samples. Strains HY164T and HY044 were motile with a polar flagellum, and had 16S rRNA gene similarity of 95.1–98.6 % to Haloactinobacterium album YIM 93306T and Haloactinobacterium glacieicola T3246-1T; strains HY168T and HY211 were most similar to Ruania albidiflava DSM 18029T (96.6 %). Phylogenetic trees based on 16S rRNA gene and whole genome sequences revealed affiliation of strains HY164T and HY168T to the family Ruaniaceae , representing novel lineages in the genera Haloactinobacterium and Ruania , respectively, which was also supported by the results for average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH). For all isolates, the principal cellular fatty acids were anteiso-C15 : 0 and iso-C14 : 0. HY164T and HY168T had MK-8(H4) as the predominant isoprenoid quinone, diphosphatidylglycerol, phosphatidylglycerol, several unidentified phospholipids and glycolipids as common polar lipids while the latter strain additionally contained one unidentified aminophospholipid and one unidentified phosphoglycolipid. Besides sharing alanine, glutamic acid and lysine with HY164T, HY168T additionally contained 2,4-diaminobutyric acid in the cell-wall peptidoglycan. The whole-cell sugars of HY164T were ribose and rhamnose, while HY168T only included the latter. The DNA G+C contents of HY164T and HY168T were 71.0 and 69.1 mol%, respectively. Combining the polyphasic taxonomic data, HY164T (=CGMCC 4.7606T=JCM 33464T) is classified as representing a novel species of the genus Haloactinobacterium with the proposed name Haloactinobacterium kanbiaonis sp. nov., and HY168T (=CGMCC 1.16970T=JCM 33465T) is proposed to represent a novel species of the genus Ruania with the name Ruania zhangjianzhongii sp. nov.

Ltd. in Pu'er city, Yunnan, south-west China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belonged to the genus Massilia . The closest phylogenetic relative was Massilia arenae CICC 24458T (99.5 %), followed by M. timonae CCUG45783T (97.9 %), M. oculi CCUG43427AT (97.8 %), and M. aurea DSM 18055T (97.8 %). The major fatty acids were C16 : 0 and C16 : 1  ω7c and/or C16 : 1  ω6c. The major respiratory quinone was ubiquinone Q-8 and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. Genome sequencing revealed a genome size of 5.97 M bp and a G+C content of 65.4 mol%. Pairwise determined whole genome average nucleotide identity (gANI) values and digital DNA–DNA hybridization (dDDH) values were all below the threshold. Although the 16S rRNA gene similarity of stain SJY3T and Massilia arenae CICC 24458T was more than 99 %, the gANI, dDDH values and genomic tree clearly indicated that they were not of the same species. In summary, strain SJY3T represents a new species, for which we propose the name Massilia puerhi sp. nov. with the type strain SJY3T (=CGMCC 1.17158T=KCTC 82193T).
