Abstract
A novel actinomycete, designated as TPMA0078T, was isolated from a soil sample collected in Shinjuku, Tokyo, Japan. 16S rRNA gene sequence analysis indicated that strain TPMA0078T belongs to the genus Actinoplanes and is closely related to Actinoplanes regularis IFO 12514T (99.86% 16S rRNA gene sequence similarity). The spores of strain TPMA0078T were motile, and the sporangia were cylindrical. The diamino acids in the cell wall peptidoglycan of strain TPMA0078T were meso-diaminopimelic acid and 3OH-meso-diaminopimelic acid. Whole-cell sugars were glucose and mannose, with galactose as a minor component. The major cellular fatty acids identified were iso-C15:0, iso-C16:0, and anteiso-C17:0. The predominant menaquinone was MK-9(H4), and the principal polar lipid was phosphatidylethanolamine. These chemotaxonomic properties of strain TPMA0078T were consistent with those of Actinoplanes. Meanwhile, digital DNA-DNA hybridization and average nucleotide identity values showed low relatedness between strain TPMA0078T and A. regularis NBRC 12514T. Furthermore, several phenotypic properties of strain TPMA0078T distinguished it from those of closely related species. Based on its genotypic and phenotypic characteristics, strain TPMA0078T represents a novel species of the genus Actinoplanes, for which the name Actinoplanes kirromycinicus sp. nov. is proposed. The type strain is TPMA0078T (=NBRC 116422T = TBRC 18262T).

Abstract
In 1973, Eli Lilly and Company described the filamentous actinomycete producing the glycopeptide antibiotic A477 as an Actinoplanes species on the basis of its morphological and physiological features and deposited it as NRRL 3884T. In this paper, we report that the phylogenetic analysis based on the 16S rRNA gene sequence and the whole genome phylogenomic study indicate that NRRL 3884T forms a distinct monophyletic line within the genus Actinoplanes, being most closely related to Actinoplanes octamycinicus NBRC 14524T [99.6 % 16S rRNA gene similarity, 89.4 % average nucleotide identity (ANI), 46.0 % digital DNA-DNA hybridization (dDDH)] and Actinoplanes ianthinogenes NBRC 13996T (98.8 % 16S rRNA gene similarity, 89.0 % ANI, 47.0 % dDDH). NRRL 3884T forms an extensively branched, non-fragmented vegetative mycelium; either sterile aerial hyphae or regular subglobose sporangia are formed depending on cultivation conditions. The cell wall contains meso-2,6-diaminopimelic acid and 2,6-diamino-3-hydroxypimelic acid and the diagnostic sugars are glucose, mannose and ribose with a minor amount of rhamnose. The predominant menaquinone (MK) is MK-9(H4), with minor amounts of MK-9(H2), MK-9(H6) and MK-9(H8). Mycolic acids are absent. The diagnostic phospholipids are diphosphatidylglycerol and phosphatidylethanolamine. The major cellular fatty acids are anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0, with moderate amounts of anteiso-C15 : 0 and iso-C17 : 0. The genomic G+C content is 71.5 mol%. Significant differences in the genomic, morphological, chemotaxonomic and biochemical data between NRRL 3884T and the two most closely related Actinoplanes type strains clearly demonstrate that NRRL 3884T represents a novel species of the genus Actinoplanes, for which the name Actinoplanes oblitus sp. nov. is proposed. The type strain is NRRL 3884T (=DSM 116196T).

Abstract
A novel ligninase-producing and cellulose-degrading actinobacterium, designated strain NEAU-A12T, was isolated from a soil sample collected from Aohan banner, Chifeng City, Inner Mongolia Autonomous Region, PR China. A polyphasic taxonomic study was used to establish the status of strain NEAU-A12T. 16S rRNA gene sequence analysis revealed that strain NEAU-A12T belonged to the genus Actinoplanes and showed the highest similarity (98.3 %) to Actinoplanes palleronii DSM 43940T, while showing less than 98.3 % similarity to other members of the genus Actinoplanes. The phospholipid profile contained diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and glycosylphosphatidylinositol. The diagnostic sugars in cell hydrolysates were determined to be arabinose, glucose and xylose. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H4), MK-9(H6) and MK-9(H2). The major fatty acids were C15 : 0, C16 : 0, C16 : 1 ω7c and C17 : 0. Meanwhile, genomic analysis revealed a genome size of 10 192 524 bp and a DNA G+C content of 70.6 mol%, and indicated that strain NEAU-A12T had the potential to degrade lignin and cellulose, as well as produce bioactive compounds. In addition, the average nucleotide identity values between strain NEAU-A12T and its reference strains A. palleronii DSM 43940T, Actinoplanes regularis DSM 43151T, Actinoplanes philippinensis DSM 43019T, Actinoplanes xinjiangensis DSM 45184T and Actinoplanes italicus DSM 43146T were 80.3, 80.3, 84.1, 84.3 and 84.0 %, respectively. The levels of digital DNA-DNA hybridization between them were found to be 23.6 % (21.3-26.1 %), 23.8 % (21.5-26.3 %), 28.3 % (25.9-30.8 %), 28.6 % (26.0-30.9 %) and 28.4 % (26.2-31.1 %), respectively. Based on phenotypic, chemotaxonomic and genotypic data, strain NEAU-A12T is considered to represent a novel species of the genus Actinoplanes, for which the name Actinoplanes sandaracinus sp. nov. is proposed, with NEAU-A12T (=CCTCC AA 2020039T=DSM 112043T) as the type strain.
