A novel species of the genus Actinoplanes, strain LDG1-22 T , for which we propose the name Actinoplanes lichenis sp. nov., was isolated from a lichen sample collected from tree bark in Thailand. The taxonomic position of the species has been described based on a polyphasic approach. Strain LDG1-22 T produced irregular sporangia on agar media. It contained mesodiaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-9(H 4 ); the polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and phosphatidylglycerol. Whole-cell hydrolysates contained ribose, glucose, mannose and small amounts of arabinose and xylose. The major cellular fatty acids were anteiso-C 15 : 0 (31.2 %) and iso-C 16 : 0 (14.2 %). Mycolic acids were absent. The G+C content was 73.6 %. 16S rRNA gene sequence analysis of strain LDG1-22 T showed highest similarity (98.8 %) to Actinoplanes friuliensis DSM 45797 T and it clustered with Actinoplanes nipponensis JCM 3264 T and Actinoplanes missouriensis JCM 3121 T in phylogenetic tree analysis. On the basis of the phenotypic characteristics and DNA-DNA relatedness, strain LDG1-22 T could be distinguished from related species of the genus Actinoplanes and so represents a novel species of this genus. The type strain of Actinoplanes lichenis sp. nov. is LDG1-22 T (5JCM 30485 T 5TISTR 2343 T 5PCU 344 T ).The genus Actinoplanes, which belongs to the family Micromonosporaceae, was first described by Couch (1950). Members of this genus can be differentiated from other related genera in the family Micromonosporaceae by considering phenotypic characteristics, especially the formation of sporangia as well as the presence of motile spores and from chemotaxonomic characteristics, including 16S rRNA gene sequence-based phylogenetic clustering (Vobis et al., 2012). As with most actinomycetes, strains of species of the genus Actinoplanes are widely distributed in soils from various environments around the world (Couch, 1963;Parenti & Coronelli, 1979;Vobis et al., 2012). At the time of writing, the genus Actinoplanes comprises 39 species with validly published names (Parte, 2014). Some antibiotics have been shown to be produced by strains of species of Actinoplanes such as lipiarmycin (anti Gram-positive bacteria activity), teicoplanin (inhibits cell wall synthesis of Gram-positive bacteria) and friulimicin (has peptidoglycan synthesis inhibiting activity) from Actinoplanes deccanensis, Actinoplanes teichomyceticus and Actinoplanes friuliensis, respectively (Aretz et al., 2000;Coronelli et al., 1975;Somma et al., 1984).We have attempted to find a novel source, other than terrestrial soils, for isolating novel actinomycetes. Recent studies have described the isolation of different species of actinomycete from lichen, such as Actinomycetospora iriomotensis (Yamamura et al., 2011a), Actinomycetospora rishiriensis (Yamamura et al., 2011b) and Nocardioides exalbidus (Li et al., 2007). In the course of our investigation into the diversi...

“…The 16S rRNA gene sequence similarities to members of the genus Actinomycetospora ranged from 97.0 to 98.4%. [8][9][10] The phylogenetic tree constructed with 16S rRNA gene sequence data of members of the genus Actinomycetospora and related genera using the neighbor-joining method showed that strain IR73-Li102 T formed a monophyletic clade with A. chiangmaiensis, A. corticola and A. rishiriensis (Figure 1). Moreover, this clade was strongly supported by the maximum-likelihood and maximum parsimony trees with high bootstrap values.…”

“…Previously, several rare actinomycetes were isolated from lichen samples collected in Japan, and were proposed as new taxa, named Nocardioides exalbidus, Leifsonia lichenia, and Actinomycetospora rishiriensis. [6][7][8] The genus Actinomycetospora was originally proposed by Jiang et al 9 as a member of the family Pseudonocardiaceae, and was later amended by Tamura et al 10 At the time of writing, nine Actinomycetospora species have been characterized by polyphasic taxonomic approaches. The type strain of the genus Actinomycetospora, A. chiangmaiensis, was originally isolated from a soil sample in northern Thailand, whereas the other species were from soil, tree bark, and lichen samples collected in Japan.…”

[8][9][10] During a screening for lichen-associated actinomycetes, we isolated strain IR73-Li102 T from a crustose lichen sample collected from Iriomote Island, Okinawa, Japan. The aim of the present study was to determine the taxonomic position of strain IR73-Li102 T using a polyphasic taxonomic approach, which included chemotaxonomic, morphological, physiological, molecular and genomic characterizations.…”

An actinomycete strain, IR73-Li102 T , was isolated from a lichen sample obtained from Iriomote Island, Japan, and subsequently characterized using a polyphasic approach. Comparative 16S rRNA gene sequence analysis revealed that strain IR73-Li102 T had the highest sequence similarities with Actinomycetospora chiangmaiensis YIM 0006 T (98.3%), A. corticola 014-5 T (98.1%) and A. rishiriensis RI109-Li102 T (98.0%). However, DNA-DNA hybridization assays, as well as physiological and biochemical analyzes, showed that strain IR73-Li102 T could be clearly differentiated from its closest phylogenetic relatives. The strain contained meso-diaminopimelic acid, and arabinose and galactose were present in whole-cell hydrolysates. The predominant menaquinone was MK-8(H 4 ), and the diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acid was iso-C 16:0 (58%). The chemotaxonomic properties of strain IR73-Li102 T were consistent with those shared by members of the genus Actinomycetospora. On the basis of the phenotypic features and DNA-DNA hybridization data, strain IR73-Li102 T (¼ NBRC 106365 T ¼ KCTC 19783 T ) represents a novel species of the genus Actinomycetospora, for which the name Actinomycetospora iriomotensis sp. nov. is proposed.

A novel Gram-stain-positive actinobacterium, designated RI148-Li105 T , was isolated from a lichen sample from Rishiri Island, Japan, and its taxonomic position was investigated by a polyphasic approach. 16S rRNA gene sequencing study indicated that strain RI148-Li105 T was related to the type strain of Luteimicrobium subarcticum, with a similarity of 97.8%. Cells of strain RI148-Li105 T exhibited a rod-coccus cycle. The diagnostic cell-wall diamino acid of this organism was lysine and the peptidoglycan type was found to be A4a. The predominant menaquinones were MK-8(H 2 ) and MK-9(H 2 ), and the major fatty acids were iso-C 16:0 , C 17:1 x9c and C 17:0 . The DNA G þ C content was 73.6 mol%. The major phenotypic characteristics of strain RI148-Li105 T basically corresponded to those of the genus Luteimicrobium excluding the fatty acid composition. These results suggest that strain RI148-Li105 T should be affiliated with the genus Luteimicrobium. Meanwhile, DNA-DNA hybridization and some phenotypic characteristics revealed that the strain differs from L. subarcticum. Therefore, strain RI148-Li105 T represents a novel species of the genus Luteimicrobium, for which the name Luteimicrobium album sp. nov. is proposed. The type strain of Luteimicrobium album is RI148-Li105 T ( ¼ NBRC 106348 T ¼ DSM 24866 T ).
