title: Actinoplanes lichenis sp. nov., isolated from lichen.
abstract: A novel species of the genus Actinoplanes, strain LDG1-22T, 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 LDG1-22T produced irregular sporangia on agar media. It contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major menaquinone was MK-9(H4); 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-C15 : 0 (31.2 %) and iso-C16 : 0 (14.2 %). Mycolic acids were absent. The G+C content was 73.6 %. 16S rRNA gene sequence analysis of strain LDG1-22T showed highest similarity (98.8 %) to Actinoplanes friuliensis DSM 45797T and it clustered with Actinoplanes nipponensis JCM 3264T and Actinoplanes missouriensis JCM 3121T in phylogenetic tree analysis. On the basis of the phenotypic characteristics and DNA-DNA relatedness, strain LDG1-22T 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 LDG1-22T ( = JCM 30485T = TISTR 2343T = PCU 344T).
