An aerobic, Gram-stain-positive, non-motile, dull-yellow, short rod-shaped actinomycete strain, designated G10T, was isolated from Tagetes patula (marigold) roots collected from Goyang in the Republic of Korea. The isolate showed best growth on Reasoner's 2A agar at 25 °C, pH 6.5.0 and with 0% NaCl (w/v). The strain was negative for oxidase activity and positive for catalase activity. On the basis of 16S RNA gene sequence similarity, strain G10T was affiliated to the genus Nocardioides and the closest species were Nocardioides glacieisoli HLT3-15T (98.8 %), Nocardioides zhouii HLT2-9T (98.8 %), Nocardioides ganghwensis JC2055T (98.7 %), Nocardioides cavernae YIM A1136T (98.6 %), Nocardioides flavus Y4T (98.5 %), Nocardioides oleivorans DSM 16090T (98.3 %), Nocardioides alpinus Cr7-14T (98.2 %), Nocardioides exalbidus DSM 22017T (98.1 %) and Nocardioides hwasunensis KCTC 19197T (98.1 %). Strain G10T formed a monophyletic cluster with N. glacieisoli HLT3-15T, N. zhouii HLT2-9T and N. hwasunensis KCTC 19197T in all phylogenetic trees. The cell-wall peptidoglycan of strain G10T contained ll-diaminopimelic acid as the diagnostic amino acid. The predominant fatty acids were iso-C16 : 0 and C17 : 1  ω8c. MK-8(H4) was the major isoprenoid quinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. Average nucleotide identity and digital DNA–DNA hybridization values were 78.6–88.7 % and 21.5–36.2 %, respectively, with the type strains of related species of the genus Nocardioides , suggesting that strain G10T represents a novel species. The genome of strain G10T is 4 231 000 bp long with a DNA G+C content of 71.5 mol% and encodes 4071 predicted proteins, six rRNAs and 46 tRNAs. The genome of strain G10T comprises the biosynthetic gene cluster for T3PKS, terpene, NRPS-like fragment and RRE-containing element as secondary metabolites. The results of taxonomic, phylogenetic, biochemical, chemotaxonomic and genomic analysis clearly supported that strain G10T represent a novel species within the genus Nocardioides , for which the name Nocardioides baculatus sp. nov is proposed and the type strain is G10T (=KCTC 49626T=NBRC 114801T).

Faecal Samples

Four strains (9CBEGH2T, 9BBH35, 6BBH38 and 6EGH11) of Gram-stain-positive, obligately anaerobic, rod-shaped bacteria were isolated from faecal samples from healthy Japanese humans. The results of 16S rRNA gene sequence analysis indicated that the four strains represented members of the family Erysipelotrichaceae and formed a monophyletic cluster with ‘ Absiella argi ’ strain N6H1-5 (99.4% sequence similarity) and Eubacterium sp. Marseille-P5640 (99.3 %). Eubacterium dolichum JCM 10413T (94.2 %) and Eubacterium tortuosum ATCC 25548T (93.7 %) were located near this monophyletic cluster. The isolates, 9CBEGH2T, ‘ A. argi ’ JCM 30884 and Eubacterium sp. Marseille-P5640 shared 98.7–99.1% average nucleotide identity (ANI) with each other. Moreover, the in silico DNA–DNA hybridization (DDH) values among three strains were 88.4–90.6%, indicating that these strains represent the same species. Strain 9CBEGH2T showed 21.5–24.1 % in silico DDH values with other related taxa. In addition, the ANI values between strain 9CBEGH2T and other related taxa ranged from 71.2 % to 73.5 %, indicating that this strain should be considered as representing a novel species on the basis of whole-genome relatedness. Therefore, we formally propose a novel name for ‘ A. argi ’ strains identified because the name ‘ A. argi ’ has been effectively, but not validly, published since 2017. On the basis of the collected data, strain 9CBEGH2T represents a novel species of a novel genus, for which the name Amedibacterium intestinale gen. nov., sp. nov. is proposed. The type strain of A. intestinale is 9CBEGH2T (=JCM 33778T=DSM 110575T).

Lipids Profile

A Gram-stain-positive bacterial isolate, designated LMM-1652T, was isolated from an intrauterine cytobrush sample originating from a postpartum Holstein Friesian dairy cow. The strain had a rod to coccoid-shape, was catalase-positive and oxidase-negative. 16S rRNA gene sequence similarity analyses revealed that its closest relatives were Corynebacterium falsenii (97.05 % similarity), Corynebacterium jeikeium (96.83 %) and Corynebacterium urealyticum (96.82 %). Subsequent whole genome analysis showed that the genome-to-genome distance of strain LMM-1652T to its closest relatives was in the range of 23.2–24.8 %, while the average nucleotide identity values ranged from 73.7 to 74.3%, thus confirming that this isolate represents a novel species. Strain LMM-1652T was characterized by a quinone system mainly consisting of MK-9(H2) and MK-10(H2). The polar lipids profile of the strain consisted mainly of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol-mannoside, as well as one unidentified lipid lacking any functional group. Smaller amounts of four unidentified phospholipids, four unidentified glycolipids, β-gentiobiosyl diacylglycerol and four unidentified lipids lacking a functional group were also found. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid of the peptidoglycan. The fatty acid profile was mainly composed of C18 : 1 ω9c, C18 : 0 and C16 : 0. We propose a novel species of the genus Corynebacterium with the name Corynebacterium urogenitale LMM-1652T (=LMG 31163T=DSM 108747T).

China is a hotspot for hot springs and during microbial diversity analysis of Tengchong hot spring, Yunnan province, south-west PR China, two strains designated SYSU G01001T and SY-13 were isolated. SYSU G01001T and SY-13 were Gram-stain-positive, motile and spore-forming. Colonies were white, circular, raised and punctiform. SYSU G01001T and SY-13 grew at pH 6.0–9.0 (optimum pH 8.0) and at 23–37 °C (optimum 28 °C). The 16S rRNA gene sequence similarity between SYSU G01001T and SY-13 was 99.6 % but these strains shared low sequence similarity with Paenibacillus azotifigens (97.5 %) indicating that they represented a novel species. On the basis of the results, SYSU G01001T was selected for further investigations and SY-13 was considered to represent a second strain of the species. The cell wall peptidoglycan of SYSU G01001T was meso-2,6-diaminopimelic acid and MK-7 was the only respiratory quinone. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), two unidentified aminolipids (AL), two unidentified amino phospholipids (APL), an unidentified phospholipid (PL) and an unidentified polar lipid (L). The G+C content of the genomic DNA was 53.9 mol%. The average nucleotide identity (ANIb and ANIm) values between SYSU G01001T and Paenibacillus azotifigens LMG 29963T were below the cut-off level (95–96 %) recommended as the average nucleotide identity (ANI) criterion for interspecies identity. On the basis of the above results strain SYSU G01001T represents a novel species of the genus Paenibacillus , for which the name Paenibacillus tepidiphilus sp. nov. is proposed. The type strain is SYSU G01001T (=KCTC 33952T=CGMCC 1.13870T).

A novel actinobacterial strain, designated, NIO-1009T, was isolated from a marine sediment sample collected from Chorao Island, Goa, India. Phylogenetic analysis comparisons based on 16S rRNA gene sequences between strain NIO-1009T and other members of the genus Rhodococcus revealed that strain NIO-1009T had the closest sequence similarity to Rhodococcus kroppenstedtii DSM 44908T and Rhodococcus corynebacterioides DSM 20151T with 99.2 and 99.1 %, respectively. Furthermore, DNA–DNA hybridization results showed that R. kroppenstedtii DSM 44908T and R. corynebacterioides DSM 20151T were 39.5 (3.0 %) and 41.7 (2.0 %) with strain NIO-1009T, respectively, which were well below the 70 % limit for any novel species proposal. Phylogenetically strain NIO-1009T forms a stable clade with and R. kroppenstedtii DSM 44908T and R. corynebacterioides DSM 20151T with 100 % bootstrap values. Strain NIO-1009T contained meso-diaminopimelic acid as the diagnostic diamino acid and galactose and arabinose as the cell wall sugars. The major fatty acids were C16 : 0, C18 : 1ω9c, C16 : 1(ω6c and/or ω7c) and 10-methyl C18 : 0. The only menaquinone detected was MK-8(H2), while the major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and one unknown phospholipid. The G+C content of the genomic DNA was 66.9 mol%. The phenotypic and genotypic data showed that strain NIO-1009T warrants recognition as a novel species of the genus Rhodococcus for which the name Rhodococcus enclensis sp. nov., is proposed; the type strain is NIO-1009T ( = NCIM 5452T = DSM 45688T).

Genotypic Characteristics

In this study, the taxonomic position of an actinobacterium, strain YIM M 10931T, which was isolated from a mangrove sediment sample collected in Dugong Creek, Little Andaman, India, was determined by a polyphasic approach. This Gram-positive, aerobic strain produced branched substrate mycelium and aerial hyphae, which differentiated into short, hooked or spiral spore chains. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The whole cell sugars consisted of mannose, ribose, glucose, galactose and madurose. The cellular fatty acid profile mainly consisted of iso-C16 : 0, 10-methyl C18 : 0 and C16 : 0. The quinone system was predominantly composed of MK-9(H8) (45.5 %) and MK-9(H6) (39 %). The phospholipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol and two unknown phospholipids. The organism showed a combination of morphological and chemotaxonomic properties typical of members of the genus Actinomadura . Moreover, phylogenetic analysis based on a 16S rRNA gene sequence generated from the strain identified its closest relatives as Actinomadura cremea DSM 43676T (98.4 % sequence similarity), Actinomadura rifamycini DSM 43936T (97.4 %) and Actinomadura apis IM17-1T (96.9 %). It was obvious from the resulting phylogenetic trees that strain YIM M 10931T belongs to a distinct subclade within the evolutionary radiation of the genus Actinomadura . DNA–DNA hybridizations of strain YIM M 10931T with A. cremea DSM 43676T and A. rifamycini DSM 43936T were performed and further confirmed that the isolate represents a separate genomic species. Based on the phenotypic and genotypic characteristics presented, it is proposed that strain YIM M 10931T represents a novel species within the genus Actinomadura , for which the name Actinomadura sediminis sp. nov. is proposed; the type strain is YIM M 10931T ( = CCTCC AA 2010009T = DSM 45500T).

A strictly aerobic, Gram-stain-positive actinobacterial strain was isolated from a rhizosphere soil of a wild plant (Peucedanum japonicum Thumb.) collected on Mara Island, Jeju, Republic of Korea. Cells of strain RS-50T were oxidase-negative, catalase-positive, short rods and motile by means of a polar flagellum; the colonies were orange, circular, smooth and convex. meso-Diaminopimelic acid and glucose were the diagnostic diamino acid in the cell wall and the whole-cell sugar, respectively. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, two unknown phospholipids and an unknown lipid. The major fatty acids were iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The DNA G+C content was 73.6 mol%. In 16S rRNA gene sequence-based phylogenetic trees, strain RS-50T formed a tight cluster with Angustibacter luteus (99.2 % sequence similarity); both were loosely related to the suborders Kineosporiineae and Micrococcineae . The DNA–DNA relatedness value of the isolate to A. luteus KACC 14249T was 22.3±0.9 %. On the basis of the results of phenotypic analyses and DNA–DNA hybridization experiments, strain RS-50T is considered to represent a novel species of the genus Angustibacter , for which the name Angustibacter peucedani sp. nov. is proposed. The type strain is RS-50T ( = KCTC 19628T = DSM 45329T). The description of the genus Angustibacter is emended.

A facultatively anaerobic, Gram-stain-positive, rod-shaped bacterium, designated strain KB0549T, was isolated from sesame oil cake. Cells were motile, round-ended rods, and produced central or terminal spores. The cell wall peptidoglycan contained meso-diaminopimelic acid as the diamino acid. The major fatty acids were anteiso-C15 : 0 and anteiso-C17 : 0. The DNA G+C content of strain KB0549T was 51.9 mol%. On the basis of 16S rRNA gene sequence phylogeny, strain KB0549T was affiliated with the genus Paenibacillus in the phylum Firmicutes and was most closely related to Paenibacillus cookii with 97.4 % sequence similarity. Strain KB0549T was physiologically differentiated from P. cookii by the high content of anteiso-C17 : 0, inability to grow at 50 °C, spore position, and negative Voges–Proskauer reaction. Based on these unique physiological and phylogenetic characteristics, it is proposed that the isolate represents a novel species, Paenibacillus relictisesami sp. nov.; the type strain is KB0549T ( = JCM 18068T = DSM 25385T).

Phylogenetic Affiliation

A Gram-stain-positive, spore-forming actinomycete strain (HKI0641T) was isolated from a soil sample collected in the Black Forest, Germany. During screening for antimicrobial natural products this bacterium was identified as a producer of the antibiotic telomycin. Morphological characteristics and chemotaxonomic data indicated that the strain belonged to the genus Micromonospora . The peptidoglycan of strain HKI0641T contained meso-diaminopimelic acid, and the fatty acid profile consisted predominantly of anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and C16 : 0. MK-10(H4), MK-10(H2) and MK-10 were identified as the major menaquinones. To determine the taxonomic positioning of strain HKI0641T, we computed a binary tanglegram of two rooted phylogenetic trees that were based upon 16S rRNA and gyrB gene sequences. The comparative analysis of the two common classification methods strongly supported the phylogenetic affiliation with the genus Micromonospora , but it also revealed discrepancies in the assignment at the level of the genomic species. 16S rRNA gene sequence analysis identified Micromonospora coxensis DSM 45161T (99.1 % sequence similarity) and Micromonospora marina DSM 45555T (99.0 %) as the nearest taxonomic neighbours, whereas the gyrB sequence of strain HKI0641T indicated a closer relationship to Micromonospora aurantiaca DSM 43813T (95.1 %). By means of DNA–DNA hybridization experiments, it was possible to resolve this issue and to clearly differentiate strain HKI0641T from other species of the genus Micromonospora . The type strains of the aforementioned species of the genus Micromonospora could be further distinguished from strain HKI0641T by several phenotypic properties, such as colony colour, NaCl tolerance and the utilization of carbon sources. The isolate was therefore assigned to a novel species of the genus Micromonospora , for which the name Micromonospora schwarzwaldensis sp. nov. is proposed. The type strain is HKI0641T ( = DSM 45708T = CIP 110415T).

A lactic acid bacterium, strain CCTCC M 2011381T, isolated from the brine of the traditional Chinese snack, stinky tofu, was studied to determine its taxonomic position. It was a Gram-stain-positive, non-motile, facultatively anaerobic rod-shaped bacterium that did not exhibit catalase activity. The DNA G+C content of the strain was 44.1 % and its peptidoglycan was characterized by the presence of meso-diaminopimelic acid. Levels of 16S rRNA gene sequence similarity between strain CCTCC M 2011381T and the most closely related species Lactobacillus senioris JCM 17472T, Lactobacillus parafarraginis JCM 14109T and Lactobacillus diolivorans JCM 12183T were 96.5, 96.4 and 96.4 %, respectively. Combined with data from high-resolution genomic markers recA, rpoA and pheS, strain CCTCC M 2011381T was classified as representing a novel species. The strain could also be distinguished from other related species of the genus Lactobacillus by its physiological and biochemical characteristics. Based on the phylogenetic, physiological and biochemical data, it is proposed that the new isolate can be classified as representing a novel species of the genus Lactobacillus , for which the name Lactobacillus curieae sp. nov. (type strain CCTCC M 2011381T = S1L19T = JCM 18524T) is proposed.

A Gram-stain-negative, non-motile, aerobic and pleomorphic bacterium, designated BS-W13T, was isolated from a tidal flat on the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain BS-W13T grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 1.0–2.0 % (w/v) NaCl. Neighbour-joining and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain BS-W13T clustered with the type strain of Seohaeicola saemankumensis , showing the highest sequence similarity (95.96 %) to this strain. Strain BS-W13T exhibited 16S rRNA gene sequence similarity values of 95.95, 95.91, 95.72 and 95.68 % to the type strains of Sulfitobacter donghicola , Sulfitobacter porphyrae , Sulfitobacter mediterraneus and Roseobacter litoralis , respectively. Strain BS-W13T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the major fatty acid. The polar lipid profile of strain BS-W13T, containing phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid as major components, was distinguishable from those of some phylogenetically related taxa. The DNA G+C content of strain BS-W13T was 58.1 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain BS-W13T constitutes a novel genus and species within family Rhodobacteraceae of the class Alphaproteobacteria , for which the name Pseudoseohaeicola caenipelagi gen. nov., sp. nov. is proposed. The type strain is BS-W13T ( = KCTC 42349T = CECT 8724T).
