Abstract
A novel actinobacterial strain, MUSC 78T, was isolated from a mangrove soil collected from Peninsular Malaysia. The taxonomic status of this strain was determined using a polyphasic approach. Comparative 16S rRNA gene sequence analysis revealed that strain MUSC 78T represented a novel lineage within the class Actinobacteria. Strain MUSC 78T formed a distinct clade in the family Intrasporangiaceae and was related most closely to members of the genera Terrabacter (98.3-96.8 % 16S rRNA gene sequence similarity), Intrasporangium (98.2-96.8 %), Humibacillus (97.2 %), Janibacter (97.0-95.3 %), Terracoccus (96.8 %), Kribbia (96.6 %), Phycicoccus (96.2-94.7 %), Knoellia (96.1-94.8 %), Tetrasphaera (96.0-94.9 %) and Lapillicoccus (95.9 %). Cells were irregular rod-shaped or cocci and stained Gram-positive. The cell-wall peptidoglycan type was A3γ, with ll-diaminopimelic acid as the diagnostic diamino acid. The main cell-wall sugar was mannose and lower amounts of galactose and rhamnose were present. The predominant menaquinone was MK-8(H4). The polar lipid profile consisted of phosphatidylglycerol, phosphatidylinositol, phosphatidylethanolamine, diphosphatidylglycerol and phosphoglycolipid. The predominant fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. The DNA G+C content was 73.1 mol%. Based on this polyphasic study, MUSC 78T exhibited phylogenetic and phenotypic differences from members of the genera of the family Intrasporangiaceae, and therefore a novel species of a new genus, Monashia flava gen. nov., sp. nov., is proposed. The type strain of Monashia flava is MUSC 78T ( = DSM 29621T = MCCC 1K00454T = NBRC 110749T).

Abstract
A bacterial strain, PSGM2-16(T), was isolated from a pot of paddy soil grown with rice in Suwon region, Republic of Korea, and was characterized as having aerobic, Gram-stain-positive, short-rod-shaped cells with one polar flagellum. The 16S rRNA gene sequence of strain PSGM2-16(T) revealed the highest sequence similarities with Knoellia locipacati DMZ1T (97.4%), Fodinibacter luteus YIM C003(T) (97.2%) and Lapillicoccus jejuensis R-Ac013(T) (97.0%), and the phylogenetic tree showed that strain PSGM2-16(T) formed a subgroup with Ornithinibacter aureus HB09001(T) and F. luteus YIM C003(T) within the family Intrasporangiaceae. The major fatty acids (>10% of the total fatty acids) of strain PSGM2-16(T) were iso-C16 : 0, C17 : 1ω8c and iso-C14 : 0. The predominant menaquinone was MK-8(H4). The polar lipids present were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, three aminophospholipids and two phospholipids. The peptidoglycan was type A4γ with meso-diaminopimelic acid as the diagnostic diamino acid. DNA-DNA hybridization values between strain PSGM2-16(T) and closely related taxa were much less than 70%. The genomic DNA G+C content of strain PSGM2-16(T) was 70.0 mol%. On the basis of the evidence presented, it is concluded that strain PSGM2-16(T) represents a novel species of a new genus in the family Intrasporangiaceae, for which the name Oryzobacter terrae gen. nov., sp. nov. is proposed. The type strain of the type species is PSGM2-16(T) ( = KACC 17299(T)= DSM 27137(T)= NBRC 109598(T)).

Abstract
Two bacterial strains, designated KV-962(T) and KV-963, were isolated from soil collected from a field in Japan. Cells of both strains were Gram-staining-positive, non-spore-forming, short rod-shaped and motile. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these strains were related to Conexibacter woesei DSM 14684(T), with a similarity value of 98.6 %. These strains possessed MK-7 (H(4)) as the sole menaquinone and contained C(18 : 1)ω9c, C(17 : 1)ω6c and iso-C(16 : 0) as the major fatty acids. On the basis of genotypic and phenotypic characteristics, strain KV-962(T) and KV-963 were indicated as a novel species of the genus Conexibacter, for which the name Conexibacter arvalis sp. nov. is proposed. The type strain is KV-962(T) ( = DSM 23288(T) = NBRC 106558(T)).

Abstract
Three Gram-stain-positive actinobacterial strains, designated YM24-125T, YM05-1041T and YM12-102T, were isolated from marine environments. Phylogenetic analysis based on 16S rRNA gene sequences indicated that they belonged to the suborder Micrococcineae and were most closely related to members of the genus Demequina with 95.0–98.4 % sequence similarities. Cells of strains YM05-1041T and YM12-102T were rod-shaped, similar to members of the genus Demequina, while cells of strain YM24-125T were cocci to short ovoid rods. All strains grew in the absence of NaCl, but tolerated up to 15 % NaCl. The major menaquinone was demethylmenaquinone DMK-9 (H4) and the major polar lipids were phosphatidylinositol, diphosphatidylglycerol and phosphatidyglycerol. All strains contained straight-chain, iso-branched and anteiso-branched saturated fatty acids. The DNA G+C contents were 65.3–67.3 mol%. The peptidoglycans of strains YM05-1041T and YM12-102T were the A4β type with ornithine while that of strain YM24-125T contained ornithine and lysine as diamino acids. Phylogenetic analyses and differences in physiological and biochemical characteristics indicated that these three isolates represent novel species within the genus Demequina, for which the names Demequina globuliformis sp. nov. (with YM24-125T = NBRC 106266T = KCTC 19747T = MBIC 08349T as the type strain), Demequina oxidasica sp. nov. (with YM05-1041T = NBRC 106264T = KCTC 19746T = MBIC 08346T as the type strain) and Demequina aurantiaca sp. nov. (with YM12-102T = NBRC 106265T = KCTC 19745T = MBIC 08347T as the type strain) are proposed. Based on differences in the quinone system, the presence of demethylmenaquinone DMK-9(H4) and the pattern of 16S rRNA signatures, the three novel strains and current members of the genus Demequina represent a unique family within the suborder Micrococcineae. Therefore, the family Demequinaceae fam. nov. is also proposed.

Abstract
A novel strain of the class Actinobacteria was isolated from a seawater sample collected in the South China Sea using modified R2A agar plates. The strain was a Gram-stain-positive, non-motile, non-spore-forming, catalase-positive, irregular rod-shaped bacterium. The strain grew at 4–45 °C and pH 5.0–10.2, and tolerated 5 % (w/v) NaCl. Based on its 16S rRNA gene sequence, the organism was related phylogenetically to members of the genera Fodinibacter (96.7 % similarity), Lapillicoccus (96.5 %), Knoellia (95.0–95.8 %), Oryzihumus (95.6 %) and Humibacillus (95.6 %). The cell-wall contained l-ornithine as the major diagnostic diamino acid in the peptidoglycan. MK-8(H4) was the predominant menaquinone. Major cellular fatty acids were iso-C18 : 1
ω9c, iso-C16 : 0, iso-C15 : 0 and C17 : 0. The G+C content of the DNA was 69.6 mol%. Phenotypic and phylogenetic data revealed that this strain represents a novel species in a new genus of the family Intrasporangiaceae, for which the name Ornithinibacter aureus gen. nov., sp. nov. is proposed; the type strain of Ornithinibacter aureus is HB09001T (=CGMCC 1.10341T =DSM 23364T).
