Comparison of 16S rRNA gene sequences showed that strain MK44T was a member of the genus Streptomyces and most closely related to Streptomyces specialis JCM 16611T (97.9 %) and Streptomyces mayteni JCM 16957T (97.4 %). The DNA–DNA relatedness between strain MK44T and the above two related type species were 30.9±0.3 and 29.9±3.5 %, respectively, values which are far lower than the 70 % threshold for the delineation of a novel prokaryotic species. Furthermore, the results of physiological, biochemical and chemotaxonomic tests allowed further phenotypic differentiation. Therefore, it is concluded that strain MK44T represents a novel species of the genus Streptomyces , for which the name Streptomyces manganisoli sp. nov. is proposed. The type strain is MK44T (=GDMCC 4.137T=KCTC 39920T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002762
