We investigated the taxonomic relationship between Streptomyces antimycoticus, Streptomyces castelarensis, Streptomyces sporoclivatus, and Streptomyces violaceusniger. Digital DNA-DNA hybridisation using whole genome sequences and multilocus sequence analysis indicated that S. antimycoticus, S. castelarensis, and S. sporoclivatus belong to the same genomospecies. Previously reported phenotypic data also supported this synonymy. Therefore, S. castelarensis and S. sporoclivatus should be reclassified as later heterotypic synonyms of S. antimycoticus. The type strain of S. antimycoticus is NBRC 12839T (=ATCC 23880T=CBS 660.68T=RIA 1198T=CGMCC 4.1591T=DSM 40284T=JCM 4228T=JCM 4621T=KCTC 9694T=NRRL 2421T=NRRL ISP-5284T=VKM Ac-1824T). This study also revealed that genome sequence-published S. violaceusniger NRRL F-8817 should be reclassified into S. antimycoticus.
