    Abstract:
    Three Gram-positive, aerobic, non-motile, non-acid-alcohol-fast strains, designated I05-00051, I05-00074T and I03-00808, were isolated from different soil samples in Beijing and Sichuan, China. Phylogenetic analysis based on 16S rRNA gene sequences and DNA-DNA hybridization experiments revealed that these three isolates represented the same genospecies. These three strains showed <97.0 % 16S rRNA gene sequence similarity with the type strains of recognized species of the genus Saccharopolyspora, with the exception of Saccharopolyspora hirsuta subsp. hirsuta DSM 43463T (98.1 % gene sequence similarity) and Saccharopolyspora spinosa DSM 44228T (98.0 % similarity). Chemotaxonomic data, including meso-diaminopimelic acid as the diagnostic diamino acid, arabinose and galactose as predominant sugars, iso-C15 : 0, iso-C16 : 0, iso-C17 : 0 and anteiso-C17 : 0 as major fatty acids, MK-9(H4) as predominant menaquinone and polar lipids dominated by diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol, supported the affiliation of these three organisms to the genus Saccharopolyspora. The genomic DNA G+C contents of the three isolates were 68.2-69.9 mol%. The results of DNA-DNA hybridization experiments among these three isolates and S. hirsuta subsp. hirsuta DSM 43463T and S. spinosa DSM 44228T, in combination with chemotaxonomic and physiological data, demonstrated that the three new isolates represent a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora antimicrobica sp. nov. is proposed. The type strain is I05-00074T (=CCM 7463T=KCTC 19303T).
