Streptomyces kronopolitis sp. nov., an actinomycete that produces phoslactomycins isolated from a millipede (Kronopolites svenhedind Verhoeff).
A phoslactomycin-producing actinomycete, designated strain NEAU-ML8T, was isolated from a millipede (Kronopolites svenhedind Verhoeff) and characterized using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain NEAU-ML8T belongs to the genus Streptomyces with the highest sequence similarities to Streptomyces lydicus NBRC 13058T (99.39 %) and Streptomyces chattanoogensis DSM 40002T (99.25 %). The maximum-likelihood phylogenetic tree based on 16S rRNA gene sequences showed that the isolate formed a distinct phyletic line with NBRC 13058T and S. chattanoogensis DSM 40002T. This branching pattern was also supported by the tree rconstructed with the neighbour-joining method. A combination of DNA-DNA hybridization experiments and phenotypic tests were carried out between strain NEAU-ML8T and its phylogenetically closely related strains, which further clarified their relatedness and demonstrated that NEAU-ML8T could be distinguished from NBRC 13058T and S. chattanoogensis DSM 40002T. Therefore, it is concluded that strain NEAU-ML8T can be classified as representing a novel species of the genus Streptomyces, for which the name Streptomyces kronopolitis sp. nov. is proposed. The type strain is NEAU-ML8T (=DSM 101986T=CGMCC 4.7323T).
