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 strain, designated RP-AC37T, was isolated from rhizosphere soil collected on Mara Island of Jeju, Republic of Korea. Cells were aerobic, Gram-positive, oxidase-negative, catalase-positive, non-mycelium-forming and motile rods (0.6–0.7×1.9–2.4 µm). Phylogenetic analysis based on 16S rRNA gene sequences showed that the organism formed a distinct clade within the radiation occupied by the suborder Frankineae. 16S rRNA gene similarity values were less than 93.2 % to members of the suborder Frankineae and related taxa. The diamino acid isomer in the cell-wall peptidoglycan was ll-diaminopimelic acid. The major whole-cell sugars were glucose, galactose and xylose. The major menaquinone was MK-9(H4). The polar lipids were diphosphatidylglycerol, phosphatidylcholine and phosphatidylinositol. The cellular fatty acids were straight-chain, unsaturated and saturated, with a significant amount of tuberculostearic acid (10-methyl-C18 : 0). The DNA G+C content was 73.2 mol%. The combination of morphological, chemotaxonomic and phylogenetic data clearly separate the isolate from members of known genera of the suborder Frankineae and related taxa, suggesting that the isolate represents a novel species in a new genus in this suborder, for which the name Motilibacter peucedani gen. nov., sp. nov. is proposed; the type strain is RP-AC37T ( = KCTC 19630T = DSM 45328T).

A novel actinomycete, designated strain NEAU-Jh2-17T, was isolated from muddy soil collected from a riverbank in Jilin Province, northern China, and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain NEAU-Jh2-17T showed highest similarity to those of Streptomonospora nanhaiensis 12A09T (99.26 %), Nocardiopsis rosea YIM 90094T (97.31 %), Streptomonospora halophila YIM 91355T (97.24 %) and Streptomonospora arabica S186T (97.02 %). Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain NEAU-Jh2-17T fell within a cluster consisting of the type strains of species of the genus Streptomonospora and formed a stable clade with S. nanhaiensis 12A09T in trees generated with two algorithms. Key morphological and chemotaxonomic properties also confirmed the affiliation of strain NEAU-Jh2-17T to the genus Streptomonospora. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid and whole-cell hydrolysates contained glucose, ribose and galactose. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylcholine (PC), phosphatidylinositol (PI), phosphatidylinositol mannoside (PIM), two unknown phospholipids (PLs) and two unknown glycolipids (GLs). The predominant menaquinones were MK-10(H2), MK-10(H8), MK-10(H6) and MK-10(H4). Major fatty acids were C18 : 0 10-methyl, anteiso-C17 : 0, C16 : 0 10-methyl, iso-C15 : 0, C17 : 0 10-methyl and C18 : 0. The DNA G+C content was 71.82 mol%. However, a combination of DNA–DNA hybridization results and some phenotypic characteristics demonstrated that strain NEAU-Jh2-17T could be distinguished from its closely related relatives. Therefore, strain NEAU-Jh2-17T is considered to represent a novel species of the genus Streptomonospora, for which the name Streptomonospora halotolerans sp. nov. is proposed. The type strain is NEAU-Jh2-17T ( = CGMCC 4.7218T = JCM 30347T).

A novel Gram-reaction-positive, aerobic and non-spore-forming rod-shaped bacterial strain, YS17T, was isolated from ripened Pu′er tea. Growth of the strain was observed at 15–50 °C (optimum 30–37 °C) and at pH 5.5–10.5 (optimum 6.0–9.5). Phylogenetic analysis of 16S rRNA gene sequences indicated that the strain represented a member of the genus Aeromicrobium. The strains most closely related to YS17T were Aeromicrobium erythreum DSM 8599T, Aeromicrobium alkaliterrae JCM 13518T and Aeromicrobium ginsengisoli JCM 14732T, with 16S rRNA gene sequence similarities of 96.8, 96.8 and 96.7 %, respectively. DNA–DNA hybridization of YS17T with the type strains of the most closely related species, A. erythreum DSM 8599T, A. alkaliterrae JCM 13518T and A. ginsengisoli JCM 14732T, yielded reassociation values of 10.9, 16.8 and 10.9 %, respectively. The diagnostic diamino acid of the cell wall peptidoglycan was ll-diaminopimelic acid. The predominant menaquinones were menaquinone MK-9(H4) (76 %) and MK-8(H4) (17 %). The major fatty acids were C16 : 0, 10-methyl C18 : 0 and C18 : 1ω9c. The DNA G+C content of YS17T was 66 mol%. YS17T could be differentiated from recognized species of the genus Aeromicrobium on the basis of phenotypic characteristics, chemotaxonomic differences, phylogenetic analysis and DNA–DNA hybridization data. On the basis of evidence from the polyphasic analyses performed as part of this study a novel species, Aeromicrobium camelliae sp. nov., is proposed, with strain YS17T ( = CGMCC 1.12942T = JCM 30952T) as the type strain.
