ABSTRACT
A novel actinomycete, designated strain KC 198T, was isolated from rare earth mine. The results of analysis of the 16S rRNA gene sequence indicated that KC 198T was most closely related to Actinorectisporaindica YIM 75728T (98.4â%). Aerial hyphae differentiated into long, straight chains of cylindrical spores. Growth was observed at 10-45 °C (optimum 28 °C), with 0-10â% (w/v) NaCl (optimum, in the absence of NaCl) and at pH 6.0-8.0 (optimum pH 7.0). KC 198T possessed MK-9(H4) as the predominant respiratory quinone and a minor amount of MK-10(H4). Polar lipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside. Three unidentified lipids were also detected. The main cellular fatty acids were iso-C16ââ0 (30.9â%), iso-C16ââ1H (22.9â%) and iso-C15ââ0 (14.8â%). The genomic DNA G+C content was 66.8 mol%. On the basis of the phenotypic and genotypic characteristics, we propose that strain KC 198T represents a novel species of the genus Actinorectispora. The name Actinorectispora metalli sp. nov. is, therefore, proposed for the novel species with the type strain KC 198T (=CCTCC AA 2015043T=KCTC 39718T). The description of the genus Actinorectispora has also been emended.
