title: Two new carbapenem antibiotic-producing actinomycetes: Kitasatosporia papulosa sp. nov. and Kitasatosporia grisea sp. nov.
abstract: Two new carbapenem antibiotic-producing actinomycetes, the cell-walls of which contain LL-diaminopimelic acid and meso-diaminopimelic acid, were isolated from soil. The two strains were subjected to taxonomic studies, which involved morphological, cultural, physiological and chemotaxonomical characterization, the latter including the cell-wall chemo-type, whole-cell sugar composition, phospholipid composition, menaquinone system and DNA base composition. These strains were identified as new species of the genus Kitasatosporia. The proposed names are Kitasatosporia papulosa for strain AB-110 (IAM 13637, FERM 9000, JCM 7250) and Kitasatosporia grisea for strain AA-107 (IAM 13638, JCM 7249).
