A novel actinobacterial strain, designated N237T, was isolated from sediment soil of wetlands at Meonmulkkak, Dongbaek-Dongsan, the lava forest, Gotjawal, Jeju, Republic of Korea. Cells of strain N237T were Gram-stain-positive, non-motile rods and formed pale yellow colonies on ten-fold diluted Reasoner's 2A agar. Strain N237T contained iso-C16 : 0 and C17 : 1ω8c as the major fatty acids, MK-9(H4) as the predominant isoprenoid quinone and meso-DAP as the diamino acid in the peptidoglycan. It contained diphosphatidylglycerol, phosphatidylinositol polymannosides, an unidentified phospholipid, an unidentified aminophospholipid, an unidentified aminolipid, two unidentified glycophospholipids, three unidentified glycolipids and two unidentified lipids as polar lipids. The DNA G+C content was 68.1 mol%. Strain N237T formed a separate lineage in the genus Jatrophihabitans, as demonstrated by phylogenetic analysis based on 16S rRNA sequencing. It was most closely related to Jatrophihabitans soli KIS75-12T (95.6 % sequence similarity). The combined phenotypic, chemotaxonomic and phylogenetic characteristics supported the conclusion that strain N237T represents a novel species in the genus Jatrophihabitans, for which the name Jatrophihabitans telluris sp. nov. is proposed. The type strain is N237T (=KCTC 39922T=NRRL B-65477T).
