Actinomycete strain MCCC 1A01550T, isolated from the national mangrove reserve in Fujian Province, China, was determined to belong to the genus Streptomyces based on a polyphasic approach. The cell wall of the novel strain contained LL-diaminopimelic acid and galactose. The predominant menaquinones were MK-9(H4) and MK-9(H6) and the major fatty acids were iso-C16 : 0, cis9-C16 : 1 and C16 : 0. The diagnostic phospholipid was phosphatidylethanolamine. The DNA G+C content of the novel strain was 71.6 mol%. Phylogenetic analysis of 16S rRNA gene sequences confirmed the separation of the novel strain from recognized members of the genus Streptomyces available in public databases. DNA–DNA relatedness values between strain MCCC 1A01550T and the type strains of three related species ranged from 21.29 % to 43.38 %. Based on its phenotypic and genotypic characteristics, strain MCCC 1A01550T (=DSM 41903T=CGMCC 4.3534T) represents the type strain of a novel species, for which the name Streptomyces xiamenensis sp. nov. is proposed.
The GenBank/EMBL/DDBJ accession number for the 16S rRNA sequence of strain MCCC 1A01550T is EF012099.
Details of the cellular fatty acid content of strain MCCC 1A01550T are presented in a supplementary table that is available with the online version of this paper.
