A Gram-positive, strictly aerobic actinobacterium, designated BMP B8004T, was isolated from desert soil collected in Xinjiang Province, Northwest China. It produced an extensively branched non-fragmenting substrate mycelium, and very scanty aerial mycelium that formed a short hooked chain of arthrospores with a smooth surface. Optimum growth occurred at 28 °C, pH 7.0 and 0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain BMP B8004T formed a distinct phyletic lineage within the genus Actinomadura. It shared the highest 16S rRNA gene sequence similarity to Actinomadura apis IM17-1T (99.2 %) and Actinomadura rifamycini NBRC 14183T (98.6 %). However, it could be distinguished from the two closest strains based on the low levels of DNA-DNA relatedness (52.7±0.7 and 45±1.8 %, respectively). Chemotaxonomic characteristics, including the main phospholipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides, the major menaquinones MK-9(H6) and MK-9(H8), the predominant fatty acids iso-C16 : 0, C16 : 0, C18 : 0 10-methyl and C18 : 1ω9c, were also consistent with the properties of the genus Actinomadura. The DNA G+C content of strain BMP B8004T was 71.9 mol%. Based on phenotypic and genotypic features, strain BMP B8004T is considered to represent a novel species of the genus Actinomadura, for which the name Actinomadura deserti sp. nov. is proposed. The type strain is BMP B8004T (=CGMCC 4.7432T=KCTC 39998T).

UI MeSH Term Description Entries
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
