Abstract
A novel ikarugamycin-producing actinomycete, designated strain NEAU-Da3T, was isolated from soybean root [Glycine max (L.) Merr.] and characterized using a polyphasic approach. 16S rRNA gene sequence similarity studies showed that strain NEAU-Da3T belonged to the genus
Streptomyces
, and was most closely related to
Streptomyces carpaticus
NRRL B-16359T (99.5 %),
Streptomyces cheonanensis
VC-A46T (99.3 %) and
Streptomyces xiamenensis
MCCC 1A01550T (97.2 %); similarities to other type strains of species of the genus
Streptomyces
were lower than 97.1 %. The maximum-likelihood phylogenetic tree based on 16S rRNA gene sequences showed that the isolate formed a distinct phyletic line with
S. carpaticus
NRRL B-16359T,
S. cheonanensis
VC-A46T and
S. xiamenensis
MCCC 1A01550T. This branching pattern was also supported by the tree reconstructed with the neighbour-joining method. A comparative study between strain NEAU-Da3T and the type strains of the closest related species of the genus
Streptomyces
revealed that it differed from them in morphological, physiological and biochemical characteristics. Therefore, it is proposed that strain NEAU-Da3T represents a novel species of the genus
Streptomyces
, for which the name
Streptomyces
harbinensis sp. nov. is proposed. The type strain is NEAU-Da3T ( = CGMCC 4.7047T = DSM 42076T).
