摘要:
A biologically pure culture of Micromonospora purpureochromogenes ssp. Wuxiensis and its use in an aerobic fermentation process to produce the antibacterial and antiparasitic agent LL-D42067.alpha..
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:
The invention is a process for the production by fermentation of the antibacterial and antiparasitic agents designated LL-D42067.alpha., to methods for its recovery and concentration from crude solutions and to processes for its purification. The invention includes within its scope the biologically pure culture of the antibiotic.
摘要:
This invention relates to antibiotic LL-E19020.alpha. and LL-E19020.beta. derived from the microorganism Streptomyces lydicus subspecies tanzanius NRRL 18036, which are useful as an antibacterial agent.
摘要:
This invention provides a method for treating chronic respiratory disease, fowl cholera and necrotic enteritis in infected birds, by orally administering thereto a pharmaceutically effective amount of antibiotic LL-E19020.alpha., antibiotic LL-E19020.beta. or a physiologically acceptable salt thereof.
摘要:
This disclosure describes four new antibacterial agents designated LL-C08078.alpha..sub.1, LL-C08078.alpha..sub.2, LL-C08078.alpha..sub.3 and LL-C08078.beta. produced in a microbiological fermentation under controlled conditions using a new strain of a new species of the genus Streptomyces called Streptomyces majorciensis Labeda, sp. nov., and mutants thereof. These new antibacterial agents are active against a variety of microorganisms and thus are useful in inhibiting the growth of such bacteria wherever they may be found. In addition, these agents are active as growth promotants in warm-blooded animals.
