A novel actinomycete, designated strain TRM 49590T, was isolated from a soil sample from Lop Nur in Xinjiang Province, China. Strain TRM 49590T was aerobic, Gram-staining-positive, with an optimum NaCl concentration for growth of 1.5 % (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 49590T 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-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. 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 49590T belongs to the genus Streptomyces with a sequence similarity of 97.16 % with the most closely related species Streptomyces sodiiphilus . Based on these observations, strain TRM 49590T 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 49590T ( = CCTCC AA 2013018T = NRRL B59109T).

Actinomycete Strain

A novel actinomycete strain, designated TRM 46012T, was isolated from sediment of Aiding Lake in Tulufan Basin (42° 64′ N 89° 26′ E), north-west China. The strain was aerobic and Gram-staining-positive with an optimum NaCl concentration for growth of 0–5 % (w/v). The isolate had sparse aerial mycelium and produced bud-shaped spores at the end of the aerial mycelium on ISP medium 4. The isolate contained ll-diaminopimelic acid as the diagnostic diamino acid and ribose as the major whole-cell sugar. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol, phosphatidylinositol mannoside, one unidentified phospholipid and three unidentified glycolipids. The predominant menaquinones were MK-9(H6), MK-9(H8) and MK-9(H4). The major fatty acids were iso-C16 : 0, anteiso-C17 : 0 and anteiso-C15 : 0. The G+C content of the DNA was 74.4 mol%. Phylogenetic analysis showed that strain TRM 46012T had 16S rRNA gene sequence similarity of 95.7 % with the most closely related species with a validly published name, Streptomyces cheonanensis , and it could be distinguished from all species in the genus Streptomyces by using the data from this polyphasic taxonomic study. On the basis of these data, strain TRM 46012T should be designated as a representative of a novel species of the genus Streptomyces , for which the name Streptomyces aidingensis sp. nov. is proposed. The type strain is TRM 46012T ( = CGMCC 4.5739T = NBRC 108211T).

Phylogenetic inference based on 16S rRNA gene sequences showed that the strain formed a tight phyletic lineage with members of the genus Brevibacterium . Strain SJ5-8T was most closely related to Brevibacterium yomogidense MN-6-aT, Brevibacterium daeguense 2C6-41T and Brevibacterium salitolerans TRM 415T with similarities of 98.9, 97.5 and 97.4 %, respectively. The DNA–DNA relatedness values between strain SJ5-8T and the type strains of B. yomogidense , B. daeguense and B. salitolerans were 51.7±1.9 %, 22.2±4.0 % and 52.4±3.8 %, respectively. Chemotaxonomic data (major sole isoprenoid quinone, MK-8(H2); major diagnostic diamino acid, meso-diaminopimelic acid; major polyamines, putrescine and cadaverine; major cellular fatty acids, anteiso-C15:0, iso-C15:0 and anteiso-C17:0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 69.3 mol%) also supported the affiliation of strain SJ5-8T to the genus Brevibacterium . Therefore, strain SJ5-8T represents a novel species of the genus Brevibacterium , for which the name Brevibacterium jeotgali sp. nov. is proposed.

A Gram-staining-positive, aerobic and non-motile strain, 0704P10-1T, was isolated from hydrothermal sediment of the Indian Ocean. Phylogenetic, phenotypic and chemotaxonomic data for the organism supported that it belonged to the genus Janibacter .
