title: Streptomyces xiamenensis sp. nov., isolated from mangrove sediment.
abstract: Actinomycete strain MCCC 1A01550(T), 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(H(4)) and MK-9(H(6)) and the major fatty acids were iso-C(16 : 0), cis9-C(16 : 1) and C(16 : 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 1A01550(T) and the type strains of three related species ranged from 21.29 % to 43.38 %. Based on its phenotypic and genotypic characteristics, strain MCCC 1A01550(T) (=DSM 41903(T)=CGMCC 4.3534(T)) represents the type strain of a novel species, for which the name Streptomyces xiamenensis sp. nov. is proposed.
