  • Out of 826 isolates of Streptomyces isolated from different soils, 65 isolates were selected and identified according to their morphological and physiological characters. A total of 46 species of Streptomyces were identified, and the following 38 species were newly recorded in Korea. 1) Melanoid pigments producing group; S. lavendulae, S. purpurascens, S. violarus, S. lateritius, S. olivochromogenes, S. purpeofuscus, S. fulvoviolaceus, S. gallilaeus, S. naganishii, S. hygroscopicus subsp. ossamyceticus, S. nevagawaensis, S. anandii, S. phaeopurpureus, S. mirabilis, S. arenae, S. massasporeus, S. eurythermus, S. tuirus. 2) Melanoid pigments non-producing group; S. fellus, S. flavidovirens, S. exfoliatus, S. fumanus, S. termitum, S. glomeroaurantiacus, S. luteofluorescens, S. prunicolor, S. fradiae, S. tauricus, S. griseolus, S. misakiensis, S. poonensis, S. antimycoticus, S. diastaticus subsp. ardesiacus, S. nigrifaciens, S. tendae, S. narbonensis subsp. josamvceticus, S. atroolivaceus, S. chrysomallus subsp. fumigatus.

  • Identification of the Actinomycetes isolate strain No. 497 producing an actinomycin antibiotic MT-497 was performed by ISP and chemotaxonomic methods. The strain Nu. 497 formed various shapes of sclerotia and smooth surface spore. Menaquinone MK-9 ($H_6, H_8$) and iso-, anteiso-branched $C_{15}C_{17}$ fatty acids were detected from whole cell extract. The wall chemotype of stram No. 497 was decided as wall chemotype I from the analysis of DAP isomer, peptidoglycan type and sugar pattern. From these morphological, chemotaxonomic characteristics and analysis of various physiological characteristics. the strain No. 497 was identified as Streptomyces nigrifaciens.
