sp. nov., a novel actinomycete isolated from sandy soil.

A novel mycelium-forming actinomycete, designated strain NEAU-S30, was isolated from the sandy soil of a sea beach in Shouguang city, Shandong province, PR China. The strain developed long chains of non-motile cylindrical spores with smooth surfaces on aerial mycelia. The results of a polyphasic taxonomic study indicated that NEAU-S30 represented a member of the genus . The results of 16S rRNA gene sequence analysis indicated that NEAU-S30 was closely related to 'Glycomyces' (98.97 % sequence similarity), Glycomyces (98.90 %), '' (98.83 %) and (98.76 %). The average nucleotide identity (ANI) values between NEAU-S30 and '' NEAU-A15, DSM 44727, '' NEAU-C2 and DSM 44724 were 87.77, 87.53, 87.41 and 87.80 %, respectively. The digital DNA G+C content of the genomic DNA was 70.5 %. The whole-cell sugars contained ribose and xylose. The predominant menaquinones were MK-10(H), MK-10(H) and MK-10(H). The predominant fatty acids were anteiso-C, iso-C, anteiso-C and iso-C. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphoglycolipid, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified glycolipid. On the basis of the results of comparative analysis of genotypic, phenotypic and chemotaxonomic data, the novel actinomycete strain NEAU-S30 (=JCM 33975=CGMCC 4.7890) represents the type strain of a novel species within the genus , for which the name sp. nov. is proposed.
