A novel actinobacterial strain, designated N237, was isolated from sediment soil of wetlands at Meonmulkkak, Dongbaek-Dongsan, the lava forest, Gotjawal, Jeju, Republic of Korea. Cells of strain N237 were Gram-stain-positive, non-motile rods and formed pale yellow colonies on ten-fold diluted Reasoner's 2A agar. Strain N237 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 N237 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 KIS75-12 (95.6 % sequence similarity). The combined phenotypic, chemotaxonomic and phylogenetic characteristics supported the conclusion that strain N237 represents a novel species in the genus Jatrophihabitans, for which the name Jatrophihabitans telluris sp. nov. is proposed. The type strain is N237 (=KCTC 39922=NRRL B-65477).
从韩国济州岛熔岩林汉拿山白鹿洞面门木卡克湿地的沉积土壤中分离出了一株新型放线菌,命名为N237。菌株N237的细胞革兰氏染色呈阳性,为不运动的杆菌,在十倍稀释的Reasoner's 2A琼脂上形成淡黄色菌落。菌株N237的主要脂肪酸为异-C16 : 0和C17 : 1ω8c,主要类异戊二烯醌为MK-9(H4),肽聚糖中的二氨基酸为内消旋二氨基庚二酸。其极性脂包括双磷脂酰甘油、磷脂酰肌醇多甘露糖、一种未鉴定的磷脂、一种未鉴定的氨基磷脂、一种未鉴定的氨基脂、两种未鉴定的糖磷脂、三种未鉴定的糖脂和两种未鉴定的脂。DNA G+C含量为68.1 mol%。基于16S rRNA测序的系统发育分析表明,菌株N237在麻风树栖菌属中形成了一个独立的分支。它与麻风树栖菌KIS75-12(序列相似性为95.6%)关系最为密切。综合表型、化学分类和系统发育特征支持以下结论:菌株N237代表麻风树栖菌属中的一个新物种,为此提出名为陆地麻风树栖菌(Jatrophihabitans telluris sp. nov.)的新名称。模式菌株为N237(=KCTC 39922=NRRL B-65477)。
