A Gram-staining-positive actinobacterium, designated strain 1MR-8T, was isolated from the rhizoplane of ginseng and its taxonomic status was determined using a polyphasic approach. The isolate formed long chains of spores that were straight, cylindrical and smooth-surfaced. Strain 1MR-8T grew at 10–37 °C (optimum 28 °C), whilst no growth was observed at 45 °C. The pH range for growth was 4.0–11.0 (optimum pH 6.0–8.0) and the NaCl range for growth was 0–7 % (w/v) with optimum growth at 1 % (w/v). Strain 1MR-8T had cell-wall peptidoglycans based on ll-diaminopimelic acid. Glucose, mannose and ribose were the whole-cell sugars. The predominant isoprenoid quinones were MK-9 (H4), MK-9 (H6) and MK-9 (H8) and the major fatty acids were anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. 16S rRNA gene sequencing studies showed that the novel strain was closely related to the type strains of Streptomyces caeruleatus GIMN4T, Streptomyces curacoi NRRL B-2901T, Streptomyces capoamus JCM 4734T and Streptomyces coeruleorubidus NBRC 12761T with similarities of 98.8 %. However, DNA–DNA relatedness, as well as physiological and biochemical analyses, showed that strain 1MR-8T could be differentiated from its closest phylogenetic relatives. It is proposed that this strain should be classified as a representative of a novel species of the genus Streptomyces , with the suggested name Streptomyces panaciradicis sp. nov. The type strain is 1MR-8T ( = KACC 17632T = NBRC 109811T).

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).

Four Gram-positive, catalase-negative, coccoid isolates that were obtained from donkey oral cavities formed two distinct clonal groups when characterized by phenotypic and phylogenetic studies. From the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Streptococcus . Two of the isolates were related most closely to Streptococcus ursoris with 95.6 % similarity based on the 16S rRNA gene and to Streptococcus ratti with 92.0 % similarity based on the 60 kDa heat-shock protein gene (groEL). The other two isolates, however, were related to Streptococcus criceti with 95.0 and 89.0 % similarities based on the 16S rRNA and groEL genes, respectively. From both phylogenetic and phenotypic evidence, the four isolates formed two distinct clonal groups and are suggested to represent novel species of the genus Streptococcus . The names proposed for these organisms are Streptococcus orisasini sp. nov. (type strain NUM 1801T = JCM 17942T = DSM 25193T) and Streptococcus dentasini sp. nov. (type strain NUM 1808T = JCM 17943T = DSM 25137T).

A Gram-staining-positive, aerobic, non-motile bacterium, designated strain SJ5-8T, was isolated from seau-jeot (shrimp jeotgal), a traditional fermented seafood in South Korea. Cells were non-spore-forming rods showing catalase- and oxidase-positive reactions. Growth of strain SJ5-8T was observed at 10–37 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.5–8.5) and in the presence of 0–14 % (w/v) NaCl (optimum, 5 %). Phylogenetic inference based on 16S rRNA gene sequences showed that the strain formed a tight phyletic lineage with members of the genus Brevibacterium . Strain SJ5-8T was most closely related to Brevibacterium yomogidense MN-6-aT, Brevibacterium daeguense 2C6-41T and Brevibacterium salitolerans TRM 415T with similarities of 98.9, 97.5 and 97.4 %, respectively. The DNA–DNA relatedness values between strain SJ5-8T and the type strains of B. yomogidense , B. daeguense and B. salitolerans were 51.7±1.9 %, 22.2±4.0 % and 52.4±3.8 %, respectively. Chemotaxonomic data (major sole isoprenoid quinone, MK-8(H2); major diagnostic diamino acid, meso-diaminopimelic acid; major polyamines, putrescine and cadaverine; major cellular fatty acids, anteiso-C15:0, iso-C15:0 and anteiso-C17:0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 69.3 mol%) also supported the affiliation of strain SJ5-8T to the genus Brevibacterium . Therefore, strain SJ5-8T represents a novel species of the genus Brevibacterium , for which the name Brevibacterium jeotgali sp. nov. is proposed. The type strain is SJ5-8T ( = KACC 16911T = JCM 18571T).

The Republic

A novel Gram-staining-positive, aerobic bacterium, designed DCY80T, was isolated from soil of a ginseng field in the Republic of Korea. 16S rRNA gene sequence analysis revealed that strain DCY80T belonged to the genus Brachybacterium (95.8–98.2 % similarity) and was most closely related to Brachybacterium faecium DSM 4810T (98.2 %). Colonies were circular, entire, low-convex, opaque and 0.5–1.0 mm in diameter after growth for 2 days on TSA at 30 °C. Growth occurred at 4–34 °C (optimum, 25 °C), at pH 5.0–10.0 (optimum, pH 6.5–7.0) and in the presence of 0–7.0 % NaCl. Strain DCY80T produced siderophores and was sensitive to penicillin G, erythromycin, cefazolin, oleandomycin, ceftazidime, vancomycin, tetracycline, novobiocin, carbamicillin, rifampicin and neomycin. The DNA G+C content was 71.0 mol%. Levels of DNA–DNA relatedness between strain DCY80T and B. faecium DSM 4810T, B. paraconglomeratum KCTC 9916T, B. saurashtrense DSM 23186T and B. conglomeratum KCTC 9915T were 46.9±0.5, 28.9±0.6, 20.4±0.9 and 17.3±0.4 %, respectively. The cell-wall peptidoglycan of strain DCY80T contained meso-diaminopimelic acid as the diagnostic diamino acid. The menaquinones were MK-7 (85.8 %) and MK-8 (14.2 %). The major cellular fatty acids were anteiso-C15 : 0 (69.1 %) and anteiso-C17 : 0 (12.2 %). Phosphatidylglycerol, diphosphatidylglycerol, an unidentified glycolipid, two unidentified phospholipids and five unidentified polar lipids were found. On the basis of our phenotypic and genotypic analyses, strain DCY80T represents a novel species of the genus Brachybacterium , for which the name Brachybacterium ginsengisoli sp. nov. is proposed (type strain DCY80T = KCTC 29226T = JCM 19356T).

Physiological Properties

A novel actinobacterium, designated CFH 10395T, was isolated from the foregut of grass carp (Ctenopharyngodon idella), which had been fed with ginseng extract supplement. The taxonomic position was investigated by a polyphasic approach. Cells of CFH 10395T were Gram-staining-positive, aerobic, ovoid-shaped, non-spore-forming and non-motile. On the basis of the results of 16S rRNA gene sequence analysis, CFH 10395T was most closely related to Brachybacterium endophyticum KCTC 49087T, Brachybacterium squillarum JCM 16464T and Brachybacterium paraconglomeratum JCM 17781T (97.85%, 97.51 and 97.29% similarity, respectively). CFH 10395T grew at 4–37 °C, pH 5.0–9.0 and in the presence of up to 10.0 % NaCl (w/v). The dominant menaquinone was MK-7. The whole-cell sugars were rhamnose, glucose, mannose and galactose. meso-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The genome size was 3.99 Mbp with a DNA G+C content of 71.9 mol%. On the basis of the results of phylogenetic analysis, physiological properties, chemotaxonomic characteristics, low average nucleotide identity (ANI) and digital DDH (dDDH) results [ANI calculated using MUMmer (ANIm) <87 %, ANI calculated using blast (ANIb) <83 % and dDDH <23 %], it is concluded that CFH 10395T represents a novel species of the genus Brachybacterium , for which the name Brachybacterium subflavum sp. nov., is proposed. The type strain is CFH 10395T (=CGMCC 1.13804T=KCTC 49235T).
