Streptomyces koyangensis sp nov., a novel actinomycete that produces 4-phenyl-3-butenoic acid

A 4-phenyl-3-butenoic acid-producing actinomycete, designated strain VK-A60(T), was isolated from a soil sample collected from Koyang, Korea. Morphological and chemical characteristics of the strain were consistent with those of the genus Streptomyces. The cell wall of the strain contains LL-diaminopimelic acid. The predominant fatty acids are anteiso-C-15: 0, iso-C-16: 0 and C-16: 0. The strain formed a distinct monophyletic line within the 16S rRNA gene sequence phylogenetic tree. Analyses of its morphological, physiological and biochemical characteristics, together with random amplified polymorphic DNA and DNA-DNA relatedness data, confirmed that strain VK-A60(T) represents a novel Streptomyces taxon that is distinguishable from closely related reference strains. Strain VK-A60(T) (=KCCM 10555(T) =NBRC 100598(T)) is proposed as the type strain of a novel species, for which the name Streptomyces koyangensis sp. nov. is proposed.
