摘要:
New glycopeptides prepared by biotransformation of a vancomycin-type antibiotic by an Acinomadura citrea culture (NRRL 18382), which are useful intermediates, and methods of preparing the biotransformed intermediates by adding a vancomycin-type glycopeptide to a growing culture of Actinomadura citrea NRRL 18382 and continuing fermentation under submerged aerobic conditions, are provided.
摘要:
The present invention relates to a fermentation process for producing BMY-28960 and desxylosyl BMY-28960, and to a novel BMY-28960-producing organism belonging to the genus Actinomadura and designated as strain AB 1236 (ATCC 55208).

摘要:
Disclosed are antibiotics BU-3608 FA-1 and FA-2 and alkyl derivatives thereof. These compounds are useful as antifungal agents. BU-3608 FA-1 and FA-2 are produced from Actinomadura hibisca in a medium containing a source of D-serine.
摘要:
Antibiotic LL-D42067.alpha. derived by aerobic fermentation of the microorganism Actinomadura madurae subspecies simaoensis NRRL 15734, useful as an antibacterial and antiparasitic agent.
摘要:
A biologically pure culture of Actinomadura Sp. Strain H710-49 (ATCC 39144) is provided. The antibiotic designated BBM-1644 may be produced by fermentation of the subject culture.
摘要:
A novel macrolactam monosaccharide isolated from an antimicrobial complex 517 produced in fermentation under controlled conditions using a biologically pure culture of the microorganism Actinomadura vulgaris subsp. vulgaris ATCC 53748.
摘要:
An antibiotic complex is produced by the microorganism, Actinomadura brunnea NRRL 15216, ATCC 39216. A novel antibiotic 7-chloro-8-methoxy-2'-N-methyltetracycline, isolated from the antibiotic complex, is active against gram-positive and gram-negative aerobes.
摘要:
There is provided a new antiviral antibiotic designated herein as BU-4344V which is produced by fermentation of a BU-4344V-producing strain of a new microorganism, Actinomadura parvosata subsp. kistnae ATCC No. 55076. Antibiotic BU-4344V is recovered and purified from the fermentation broth by use of extraction, chromatography, and crystallization techniques. BU-4344V has been found to have some antibacterial activity and inhibits the growth of viruses, including influenza virus type A.
