Catellatospora, a New Genus of the Actinomycetales
Two species of the new genus Catellatospora, belonging to the “actinoplanates” group, are described, which are aerobic and produce nonfragmenting vegetative hyphae and no true aerial mycelium.
Cell wall composition of Micromonospora olivoasterospora, Micromonospora sagamiensis, and related organisms
The primary structure of the peptidoglycan of Micromonospora is discussed and 45 strains of 12 genera examined, Actinoplanes, Ampullariella, Amorphosporangium, and Dactylospora species had a significant amount of glycolate in the whole cells.
Leinamycin, a new antitumor antibiotic from Streptomyces: producing organism, fermentation and isolation.
Improved isolation methods are described along with identification of mikamycin A co-produced with leinamycin by the strain S-140, which was unstable in culture broth.
FORTIMICINS A AND B, NEW AMINOGLYCOSIDE ANTIBIOTICS
The aminoglycoside antibiotics fortimicins A and B produced by a naturally occurring strain Micromonospora sp. MK-70 were isolated from its fermentation beer. Fortimicins A and B were isolated as…
Catellatospora matsumotoense sp. nov. and C. tsunoense sp. nov., Actinomycetes Found in Woodland Soils
Two new species in the genus Catellatospora are proposed. These organisms differ in carbon utilization profiles, vitamin requirements for growth, and levels of deoxyribonucleic acid relatedness to…
Micromonospora olivasterospora sp. nov.
A new species of bacteria is described, for which the name Micromonospora olivasterospora is proposed, characterized by its olive black spore layer, spores with blunt spiny surfaces, an olive green soluble pigment, and its carbon utilization pattern.

In the course of continued screening program for new selective inhibitors of protein kinase C (PKC), fermentation broths from over 5,000 soil isolates were screened for their inhibitory activity of PKC and the pH control of fermentation resulted in an increase of the production of UCN-01 andUCN-02.
