NEO-ENACTIN, ANEW ANTIFUNGAL ANTIBIOTIC POTENTIATING POLYENE ANTIFUNGAL ANTIBIOTICS. II

TAXONOMIC STUDIES OF THE PRODUCING MICROORGANISM AND SIMULTANWOUS PRODUCTION OF BLEOMYCIN GROUP AND TREPTOTHRICIN-LIKE ANTIBIOTICS

Abstract

A new antifungal antibiotic, named neo-enactin, was produced mainly in the mycelia of strain H 829-MY 10. Strain H 829-MY 10 was identified as a Streptoverticillium, determined to be nonchromogenic, and fits in the white color-series. Although Streptoverticillium olivoreticuli is known to be chromogenic, strain H 829-MY 10 is most related to that species. Thus, strain H 829-MY 10 is named as Streptoverticillium olivoreticulisubsp. neoenacticus. Besides neo-enactin, two bleomycin-group antibiotics and two streptothricin-like antibiotics were simultaneously produced by strain H 829-MY 10.
