A Gram-stain-negative, strictly aerobic, non-motile, rod-shaped bacterium, designated CWB-1T, was isolated from a haloalkaline lake sediment sample collected from the bottom of Chaiwopu Lake, Urumchi, Xinjiang Province, PR China. Strain CWB-1T grew at 4–40 °C (optimum, 30–35 °C), pH 6.5–9.0 (optimum, pH 6.5–7.0) and with 0.5–5.5 % (w/v) NaCl (optimum, 2.5–3.0 %). Phylogenetic analyses based on the 16S rRNA gene sequence and the whole genome sequence both revealed that strain CWB-1T belonged to the family Flavobacteriaceae . The strain had the highest similarity of the 16S rRNA gene sequence to Psychroserpens jangbogonensis PAMC 27130T (92.8 %). The genome of strain CWB-1T was 3 548 011 bp long with 36.3 % DNA G+C content. The predominant fatty acids (>10 %) in the CWB-1T cells were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 1 (iso-C15 : 1 H/C13 : 0 3-OH). The major respiratory quinone was menaquinone-6 and the major polar lipids were phosphatidylethanolamine, an unidentified aminolipid and two unidentified lipids. Based on the phylogenetic analyses, as well as the phenotypic characteristics, a novel genus and species of the family Flavobacteriaceae , Paucihalobacter ruber gen. nov., sp. nov., is proposed. The type strain is CWB-1T (=KCTC 72450T=CGMCC 1.17149T).

A Gram-stain-positive, non-motile rod, designated strain SGM3-12T, was isolated from paddy soil in Suwon, Republic of Korea. 16S rRNA gene sequence analysis revealed that the strain represented a novel member of the family Microbacteriaceae . The nearest phylogenetic neighbour was Leifsonia kribbensis MSL-13T (97.4 % 16S rRNA gene sequence similarity). Strain SGM3-12T and Leifsonia kribbensis MSL-13T formed a distinct cluster within the family Microbacteriaceae . Strain SGM3-12T contained MK-12(H2) and MK-11(H2) as the predominant menaquinones with moderate amounts of MK-12 and MK-11; anteiso-C15 : 0 and iso-C16 : 0 as the major cellular fatty acids (>10 % of total); and diphosphatidylglycerol, phosphatidylglycerol and unidentified glycolipids as the polar lipids. The peptidoglycan type of the isolate was B1δ with l-Lys as the diagnostic cell-wall diamino acid. On the basis of these results, strain SGM3-12T represents a novel species within a new genus, for which the name Lysinimonas soli gen. nov., sp. nov. is proposed (the type strain of the type species is SGM3-12T = KACC 13362T = NBRC 107106T). It is also proposed that Leifsonia kribbensis be transferred to this genus as Lysinimonas kribbensis comb. nov. (the type strain is MSL-13T = DSM 19272T = JCM 16015T = KACC 21108T = KCTC 19267T).

Phylogenetic analysis of the 16S rRNA gene sequences of strains TE26T and K6 belonging to Wautersia numazuensis Kageyama et al. 2005 showed the strains to be deeply intermingled among the species of the genus Cupriavidus . The comparison showed that strain TE26T was closely related to the type strains of Cupriavidus pinatubonensis (99.1 % 16S rRNA gene sequence similarity), C. basilensis (98.7 %), C. necator (98.7 %) and C. gilardii (98.0 %). However, DNA–DNA hybridization experiments (less than 20 % relatedness) demonstrated that strain TE26T is different from these Cupriavidus species. A comparative phenotypic and chemotaxonomic analysis (based on fatty acid profiles) in combination with the 16S rRNA gene sequence phylogenetic analysis and the DNA–DNA hybridization results supported the incorporation of Wautersia numazuensis into the genus Cupriavidus as Cupriavidus numazuensis comb. nov.; the type strain is TE26T ( = LMG 26411T  = DSM 15562T  = CIP 108892T).

A phytoplasma was identified in naturally infected wild Balanites triflora plants exhibiting typical witches’ broom symptoms (Balanites witches’ broom: BltWB) in Myanmar. The 16S rRNA gene sequence revealed that BltWB phytoplasma had the highest similarity to that of ‘Candidatus Phytoplasma ziziphi’ and it was also closely related to that of ‘Candidatus Phytoplasma ulmi ’. Phylogenetic analysis of the 16S rRNA gene sequences indicated that the BltWB phytoplasma clustered as a discrete subclade with Elm yellows phytoplasmas. RFLP analysis of the 16S rRNA gene including the 16S–23S spacer region differentiated the BltWB phytoplasma from ‘Ca. P. ziziphi ’, ‘Ca. P. ulmi ’ and ‘Candidatus Phytoplasma trifolii ’. Analysis of additional ribosomal protein (rp) and translocase protein (secY) gene sequences and phylogenetic analysis of BltWB showed that this phytoplasma was clearly distinguished from those of other ‘Candidatus Phytoplasma ’ taxa. Taking into consideration the unique plant host and the restricted geographical occurrence in addition to the 16S rRNA gene sequence similarity, the BltWB phytoplasma is proposed to represent a novel taxon, ‘Candidatus Phytoplasma balanitae’.

A novel Gram-staining-negative, motile, non-pigmented, facultatively anaerobic, spirillum-shaped, halophilic and alkaliphilic bacterium, designated strain GCWy1T, was isolated from water of the coastal–marine wetland Gomishan in Iran. The strain was able to grow at NaCl concentrations of 1–10 % (w/v) and optimal growth was achieved at 3 % (w/v). The optimum pH and temperature for growth were pH 8.5 and 30 °C, while the strain was able to grow at pH 7.5–10 and 4–40 °C. Phylogenetic analysis based on the comparison of the 16S rRNA gene sequence placed the isolate within the class Gammaproteobacteria as a separate deep branch, with 92.1 % or lower sequence similarity to representatives of the genera Saccharospirillum and Reinekea and less than 91.0 % sequence similarity with other remotely related genera. The major cellular fatty acids of the isolate were C18 : 1ω7c, C16 : 0 and C17 : 0, and the major components of its polar lipid profile were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The cells of strain GCWy1T contained the isoprenoid quinones Q-9 and Q-8 (81 % and 2 %, respectively). The G+C content of the genomic DNA of this strain was 52.3 mol%. On the basis of 16S rRNA gene sequence analysis in combination with chemotaxonomic and phenotypic data, strain GCWy1T represents a novel species in a new genus in the family ‘ Saccharospirillaceae ’, order Oceanospirillales , for which the name Salinispirillum marinum gen. nov., sp. nov. is proposed.

A Gram-staining-positive, non-motile, strictly aerobic, non-spore-forming, vibrio-shaped bacterial strain, CL-TW6T, was isolated from a reservoir seawater sample from a solar saltern in Korea. Analysis of the 16S rRNA gene sequence of strain CL-TW6T revealed a clear affiliation with the family Microbacteriaceae . Strain CL-TW6T showed the closest phylogenetic relationships with the genera Yonghaparkia and Microcella , with 16S rRNA gene sequence similarity of 94.8–95.3 %. The strain grew in the presence of 1–9 % sea salts, at 15–35 °C and at pH 7.0–9.0. The major cellular fatty acids of strain CL-TW6T were anteiso-C15 : 0 (32.6 %), iso-C16 : 0 (20.4 %), iso-C15 : 0 (13.2 %) and iso-C14 : 0 (11.8 %) and the major menaquinones were MK-9 and MK-10. Cell-wall analysis showed that the peptidoglycan of strain CL-TW6T contained 2,4-diaminobutyric acid, alanine, glycine and glutamic acid. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C content of strain CL-TW6T was 60.0 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed clearly that strain CL-TW6T could be distinguished from members of the family Microbacteriaceae with validly published names. Thus, strain CL-TW6T should be classified as representing a novel genus and species in the family Microbacteriaceae , for which the name Pontimonas salivibrio gen. nov., sp. nov. is proposed. The type strain of Pontimonas salivibrio is CL-TW6T ( = KCCM 90105T  = JCM 18206T).

A novel actinobacterium, designated strain CFH S0261T, was isolated from a sediment sample of the Yellow River. The taxonomic position of the strain was investigated by using a polyphasic approach. Cells of strain CFH S0261T were Gram-reaction-positive, aerobic, non-motile. Growth occurs at 15–37 °C, pH 6.0–8.0 and with 0–9.0 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain CFH S0261T was a member of the genus Amycolatopsis . The 16S rRNA gene sequence similarity indicated that strain CFH S0261T is most closely related to the type strains of Amycolatopsis niigatensis LC11T (98.95 %), Amycolatopsis echigonensis LC2T (98.81 %) and Amycolatopsis albidoflavus IMSNU 22139T (98.73 %). The whole-genome of CFH S0261T showed a G+C content of 69.5 mol%. The ANI values and in silico DDH values between CFH S0261T and the other species of the genus Amycolatopsis were found to be low (ANIb <90.61 % and DDH <53.40 %). The cell wall diamino acid in the peptidoglycan of strain CFH S0261T was meso-diaminopimelic acid and the whole-cell hydrolysate comprised arabinose, galactose, glucose, rhamnose and ribose. The predominant menaquinone was MK-9(H4). The major cellular fatty acids were C16 : 0, iso-C15 : 0 and iso-C16 : 0. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and four unidentified glycolipids. On the basis of phenotypic, genotypic and phylogenetic data, strain CFH S0261T represents a novel species of the genus Amycolatopsis , for which the name Amycolatopsis nivea sp. nov. is proposed. The type strain is CFH S0261T (=KCTC 39515T =CCTCC AA 2014028T).

We isolated a novel strain, R1DC25T, described as Kaustia mangrovi gen. nov. sp. nov. from the sediments of a mangrove forest on the coast of the Red Sea in Saudi Arabia. This isolate is a moderately halophilic, aerobic/facultatively anaerobic Gram-stain-negative bacterium showing optimum growth at between 30 and 40 °C, at a pH of 8.5 and with 3–5 % NaCl. The genome of R1DC25T comprises a circular chromosome that is 4 630 536 bp in length, with a DNA G+C content of 67.3 mol%. Phylogenetic analyses based on the 16S rRNA gene sequence and whole-genome multilocus sequence analysis of 120 concatenated single-copy genes revealed that R1DC25T represents a distinct lineage within the family Parvibaculaceae in the order Rhizobiales within the class Alphaproteobacteria . R1DC25T showing 95.8, 95.3 and 94.5 % 16S rRNA gene sequence identity with Rhodoligotrophos appendicifer , Rhodoligotrophos jinshengii and Rhodoligotrophos defluvii , respectively. The predominant quinone was Q-10, and the polar lipids were phosphatidylglycerol, phosphatidylcholine, diphosphatidylglycerol, as well as several distinct aminolipids and lipids. The predominant cellular fatty acids were C19 : 0 cyclo ω8c, a combination of C18 : 1 ω7c and/or C18 : 1 ω6c and C16 : 0. On the basis of the differences in the phenotypic, physiological and biochemical characteristics from its known relatives and the results of our phylogenetic analyses, R1DC25T (=KCTC 72348T;=JCM 33619T;=NCCB 100699T) is proposed to represent a novel species in a novel genus, and we propose the name Kaustia mangrovi gen. nov., sp. nov. (Kaustia, subjective name derived from the abbreviation KAUST for King Abdullah University of Science and Technology; mangrovi, of a mangrove).

A Gram-stain-positive, rod-shaped, non-motile, non-spore-forming, aerobic bacterial strain, designated BUT-2T, was isolated from activated sludge of one herbicide-manufacturing wastewater-treatment facility in Kunshan, Jiangsu province, China, and subjected to polyphasic taxonomic studies. Analysis of the 16S rRNA gene sequence indicated that strain BUT-2T shared the highest similarity with Chryseomicrobium amylolyticum (98.98 %), followed by Chryseomicrobium imtechense (98.88 %), with less than 96 % similarlity to members of the genera Paenisporosarcina , Planococcus , Sporosarcina and Planomicrobium . Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain BUT-2T clustered with C. amylolyticum JC16T and C. imtechense MW10T, occupying a distinct phylogenetic position. The major fatty acid (>10 % of total fatty acids) type of strain BUT-2T was iso-C15 : 0. The quinone system comprised menaquinone MK-7 (77.8 %), MK-6 (11.9 %) and MK-8 (10.3 %). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and some unidentified phospholipids. The cell-wall peptidoglycan type of strain BUT-2T was l-Orn-d-Glu. The genomic DNA G+C content of strain BUT-2T was 48.5 mol%. Furthermore, the DNA–DNA relatedness in hybridization experiments against the reference strain was lower than 70 %, confirming that strain BUT-2T did not belong to previously described species of the genus Chryseomicrobium . On the basis of its morphological, physiological and chemotaxonomic characteristics as well as phylogenetic analysis, strain BUT-2T is considered to represent a novel species of the genus Chryseomicrobium , for which the name Chryseomicrobium aureum sp. nov. is proposed. The type strain is BUT-2T ( = CCTCC AB2013082T = KACC 17219T).
