A novel isolate, designated strain MCCC 1A01535T, belonging to the genus Streptomyces was isolated from rhizosphere of mangrove plant Avicennia mariana Fujian Province, south China. Characterization isolate based on a polyphasic approach. Pairwise comparison 16S rRNA gene sequences revealed that 1A01535T shared 97.7 and 97.5 % sequence similarities specialis GW41-1564T hainanensis YIM47672T, respectively, its most closely related neighbours, whereas DNA–DNA relatedness value between strains 50.2 %. The major fatty acids were iso-C16 : 0, C16 0 anteiso-C15 0. These differed acid compositions strains. Strain exhibited an unusual menaquinone system comprised MK-10(H6) as predominant component moderate amounts MK-9(H6), MK-9(H8) MK-10(H8); minor MK-9(H4), MK-10(H4), MK-9(H10) MK-10(H10) also present. Based chemotaxonomic, phenotypic genotypic characteristics, is considered represent species Streptomyces, for which name avicenniae sp. nov. proposed. type (=DSM 41943T=CGMCC 4.5510T).
