Mature spore chains of strain K11-0400T had more than 20 spores per chain. The strain contained ll-diaminopimelic acid as the diamino acid in whole-cell hydrolysates, and MK-9(H6) and MK-9(H4) were the predominant menaquinones. The polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol, and no diagnostic whole-cell sugar was detected. The G+C content of the genomic DNA was 72 mol%. These morphological and chemical features of strain K11-0400T indicated that it belonged to the genus Streptomyces . Strain K11-0400T showed the highest 16S rRNA gene sequence similarity to Streptomyces naganishii NBRC 12892T (97.58 %). However, the DNA–DNA relatedness value between strain K11-0400T and the related strain was below 70 %. Based on morphological, cultural and physiological characteristics, and DNA–DNA relatedness data, strain K11-0400T should be classified as a new species of the genus Streptomyces , for which the name Streptomyces boninensis sp. nov. is proposed. The type strain of S. boninensis is K11-0400T (=NBRC 113073T, TBRC 7755T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002753
