ABSTRACT
A novel actinomycete, designated strain TRM 49590(T), was isolated from a soil sample from Lop Nur in Xinjiang Province, China. Strain TRM 49590(T) was aerobic, Gram-staining-positive, with an optimum NaCl concentration for growth of 1.5â% (w/v) and an optimum temperature for growth of 28-37 °C. The aerial mycelium was sparse, cylindrical and smooth-surfaced with irregular branches on ISP medium 4. The whole-cell sugars of strain TRM 49590(T) were ribose and glucose. The diagnostic diamino acid contained ll-diaminopimelic acid. The predominant menaquinones were MK-9(H6) and MK-9(H8), with MK-9(H4) and MK-10(H6) present in smaller amounts. The major fatty acids were iso-C16ââ0, anteiso-C15ââ0 and anteiso-C17ââ0. The G+C content of the genomic DNA was 62.2 mol%. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and phosphatidylinositol mannoside. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain TRM 49590(T) belongs to the genus Streptomyces with a sequence similarity of 97.16â% with the most closely related species Streptomyces sodiiphilus. Based on these observations, strain TRM 49590(T) is proposed to represent a novel species of the genus Streptomyces for which the name Streptomyces lopnurensis sp. nov. is suggested. The type strain is TRM 49590(T) (â=âCCTCC AA 2013018(T)â=âNRRL B59109(T)).
