A Gram-positive, non-motile, coccoid- to rod-shaped, non-spore-forming bacterium, designated strain YM18-15T, was isolated from sea sand and studied using a polyphasic taxonomic approach. Strain YM18-15T grew under both aerobic and anaerobic conditions. The cell-wall peptidoglycan type was A4β and ornithine was the diagnostic diamino acid. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unknown phospholipid, MK-8(H4) was the major menaquinone and the predominant fatty acids were anteiso-C15 : 0 and C16 : 0. The DNA G+C content was 74.2 mol%. High 16S rRNA gene sequence similarities (96.3–97.3 %) were found with the sequences of the type strains of the three genera of the family Beutenbergiaceae. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YM18-15T formed a clade with Serinibacter salmoneus, Salana multivorans and Beutenbergia cavernae. Strain YM18-15T differed from these three type strains in chemotaxonomic characteristics and in 16S rRNA gene signature nucleotides. Based on genetic and chemotaxonomic evidence, it is suggested that strain YM18-15T represents a novel species of a new genus within the family Beutenbergiaceae, for which the name Miniimonas arenae gen. nov., sp. nov. is proposed. The type strain of the type species is YM18-15T (=NBRC 106267T=KCTC 19750T=MBIC 08348T).

A novel actinomycete, designated strain Sco-B14T, was isolated from volcanic ash collected near Darangshi Oreum (a parasitic or satellite volcano) in Jeju, Republic of Korea. The organism formed well-developed, branched substrate mycelium, on which short chains of non-motile spores were arranged singly or in clusters. Aerial mycelium was not produced. Globose bodies were observed. The reverse colour of colonies was light brown to brown. Diffusible pigments were produced on ISP medium 3 and oatmeal-nitrate agar. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Sco-B14T formed a lineage within the family Micromonosporaceae and was distinct from established genera. The 16S rRNA gene sequence similarity of strain Sco-B14T to members of related genera of the family was 95.0–95.7 % to type strains of Catellatospora species, 94.7 % to Hamadaea tsunoensis IMSNU 22005T, 94.7 % to Longispora albida K97-0003T and 94.0 % to Catelliglobosispora koreensis LM 042T. 3-Hydroxydiaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. Whole-cell sugars were glucose, rhamnose, ribose, xylose, arabinose, galactose and mannose. The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol. The menaquinone profile contained MK-10(H4) (49 %), MK-9(H4) (24 %), MK-10(H6) (18 %) and MK-9(H6) (9 %). The predominant fatty acids were iso-C15 : 0 and C17 : 0. The DNA G+C content was 70.1 mol%. The combination of chemotaxonomic and phylogenetic data clearly separated the isolate from the type strains of all genera in the family Micromonosporaceae. On the basis of the phylogenetic and chemotaxonomic data presented in this paper, strain Sco-B14T is considered to represent a novel species of a new genus in the family Micromonosporaceae, for which the name Allocatelliglobosispora scoriae gen. nov., sp. nov. is proposed. The type strain of Allocatelliglobosispora scoriae is Sco-B14T (=KCTC 19661T =DSM 45362T).

A novel bacterial strain designated Gsoil 616T was isolated from a soil sample of a ginseng field in Pocheon province (South Korea) and was characterized taxonomically by using a polyphasic approach. The isolate was Gram-positive, strictly aerobic, non-motile, non-spore-forming and rod- or coccoid-shaped. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belongs to the genus Nocardioides in the family Nocardioidaceae but was clearly separated from established species of this genus. The 16S rRNA gene sequence similarities between strain Gsoil 616T and the type strains of Nocardioides species with validly published names ranged from 91.8 to 96.1 %. The G+C content of the genomic DNA was 73 mol%. Phenotypic and chemotaxonomic data [major menaquinone MK-8(H4) and major fatty acid iso-C16 : 0] supported the affiliation of strain Gsoil 616T to the genus Nocardioides. However, the results of physiological and biochemical tests allowed phenotypic differentiation of the isolate from other Nocardioides species. Therefore, strain Gsoil 616T represented a novel species within the genus Nocardioides, for which the name Nocardioides panacihumi sp. nov. is proposed. The type strain is Gsoil 616T (=KCTC 19187T =DSM 18660T).

Two Gram-stain-negative and non-flagellated bacteria, YSTF-M3T and YSTF-M6T, were isolated from a tidal flat from Yellow Sea, Republic of Korea, and subjected to a polyphasic taxonomic study. Neighbour-joining phylogenetic tree of 16S rRNA gene sequences showed that strains YSTF-M3T and YSTF-M6T belong to the genera Kordia and Olleya of the family Flavobacteriaceae , respectively. The 16S rRNA gene sequence similarities between strain YSTF-M3T and the type strains of Kordia species and between strain YSTF-M6T and the type strains of Olleya species were 94.1–98.4 and 97.3–98.3 %, respectively. The ANI and dDDH values between genomic sequences of strain YSTF-M3T and the type strains of five Kordia species and between those of strain YSTF-M6T and the type strains of three Olleya species were in ranges of 77.0–83.2 and 20.7–27.1 % and 79.4–81.5 and 22.3–23.9 %, respectively. The DNA G+C contents of strain YSTF-M3T and YSTF-M6T from genomic sequences were 34.1 and 31.1 %, respectively. Both strains contained MK-6 as predominant menaquinone and phosphatidylethanolamine as only major phospholipid identified. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strains YSTF-M3T and YSTF-M6T are separated from recognized species of the genera Kordia and Olleya , respectively. On the basis of the data presented, strains YSTF-M3T (=KACC 21639T=NBRC 114499T) and YSTF-M6T (=KACC 21640T=NBRC 114500T) are considered to represent novel species of the genera Kordia and Olleya , respectively, for which the names Kordia aestuariivivens sp. nov. and Olleya sediminilitoris sp. nov. are proposed.

Seven strains of actinobacteria, isolated from soil, wounds, urine, cow faeces, human blood and butter, were characterized by a polyphasic approach to clarify their taxonomic position. On the basis of chemotaxonomy, 16S rRNA gene analysis and DNA relatedness, strain IAM 14851T can be classified within the cluster of the genus Leucobacter and is proposed as a novel species, Leucobacter albus sp. nov., with strain IAM 14851T (=TISTR 1515T) as the type strain. The other six strains formed a phylogenetically separate branch in the family Microbacteriaceae, having the following characteristics: the major menaquinones are MK-8 to MK-10, the DNA G+C content ranges from 62 to 68 mol%, the diamino acid in the cell wall is diaminobutyric acid and the muramic acid in the peptidoglycan is of the acetyl type. The major fatty acids are 12-methyltetradecanoic acid (anteiso-C15 : 0), hexadecanoic acid (C16 : 0), 14-methyl-pentadecanoic acid (iso-C16 : 0) and 14-methyl-hexadecanoic acid (anteiso-C17 : 0). On the basis of morphological, physiological and chemotaxonomic characteristics, together with DNA–DNA hybridization and 16S rRNA gene sequence comparison, the novel genus Zimmermannella gen. nov. is proposed for these six strains. Four novel species are proposed: Zimmermannella helvola sp. nov. (type species; type strain IAM 14726T=NBRC 15775T=DSM 20419T=TISTR 1509T), Zimmermannella alba sp. nov. (type strain IAM 14724T=NBRC 15616T=TISTR 1510T), Zimmermannella bifida sp. nov. (type strain IAM 14848T=TISTR 1511T) and Zimmermannella faecalis sp. nov.
