摘要： A novel mycelium- forming actinomycete, designated strain NEAU- S30T, 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- S30T represented a member of the genus Glycomyces. The results of 16S rRNA gene sequence analysis indicated that NEAU- S30T was closely related to 'Glycomyces luteolus' (98.97 % sequence similarity), Glycomyces algeriensis (98.90 %), 'Glycomyces tritici' (98.83 %) and Glycomyces lechevalierae (98.76 %). The average nucleotide identity (ANI) values between NEAU- S30T and 'G. luteolus' NEAU-A15, G. algeriensis DSM 44727T, 'G. tritici' NEAU- C2 and G. lechevalierae DSM 44724T 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(H2), MK-10(H4) and MK- 10(H6). The predominant fatty acids were anteiso- C15:0, iso-C16:0, anteiso-C17: 0 and iso-C15:0. 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- S30T (=JCM 33975T=CGMCC 4.7890T) represents the type strain of a novel species within the genus Glycomyces, for which the name Glycomyces niveus sp. nov. is proposed.
