Abstract

A novel actinobacterium, designated TRM 44567, was isolated from cotton soil in Xinjiang Uygur Autonomous Region, northwest PR China. Growth occurred at 16–45 °C, pH 5.0–9.0, and 0–7 % (w/v) NaCl, with optimum growth at 37 °C, pH 7.0–8.0 and 1 % (w/v) NaCl, respectively. Comparative 16S rRNA gene sequence analysis indicated that strain TRM 44567 was phylogenetically most closely related to NBRC 12851 (98.48 % sequence similarity); however, the average nucleotide identity between strain TRM 44567 and NBRC 12851 was only 83.77 %. Strain TRM 44567 possessed -diaminopimelic acid as the diagnostic cell-wall diamino acid. The predominant menaquinones were MK-9(H), MK-9(H) and MK-9(H). The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. The major fatty acids were iso-C, C, anteiso-C, anteiso-C, iso-C and iso-C. The genomic DNA G+C content was 70.8 mol%. Strain TRM 44567 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is TRM 44567 (=KCTC 39957 =CCTCC AA 2017011).
