Characterization of the isolate was based on a polyphasic approach. Pairwise comparison of 16S rRNA gene sequences revealed that strain MCCC 1A01535T shared 97.7 and 97.5 % sequence similarities to Streptomyces specialis GW41-1564T and Streptomyces hainanensis YIM47672T, respectively, its most closely related neighbours, whereas the DNA–DNA relatedness value between strains MCCC 1A01535T and GW41-1564T was 50.2 %. The major fatty acids of strain MCCC 1A01535T were iso-C16 : 0, C16 : 0 and anteiso-C15 : 0. These differed from the fatty acid compositions of related strains. Strain MCCC 1A01535T exhibited an unusual menaquinone system that comprised MK-10(H6) as the predominant component and moderate amounts of MK-9(H6), MK-9(H8) and MK-10(H8); minor amounts of MK-9(H4), MK-10(H4), MK-9(H10) and MK-10(H10) were also present. Based on its chemotaxonomic, phenotypic and genotypic characteristics, strain MCCC 1A01535T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces avicenniae sp. nov. is proposed. The type strain is MCCC 1A01535T (=DSM 41943T=CGMCC 4.5510T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.009357-0
