Abstract:
A novel actinomycete herein designated Micromonospora rhodorangea elaborates a product having substantial antibacterial activity, said activity being due primarily to a novel antibiotic herein designated Antibiotic G-418. The disclosure sets forth methods for producing, isolating and using said antibiotic.
Abstract:
This invention relates to new polypeptide antibiotics designated LL-BO2964.alpha., LL-BO2964.beta., LL-BO2964.gamma., and a mixture thereof designated LL-BO2964, produced during microbiological fermentation, under controlled conditions, using a new strain of Streptomyces coeruleorubidus subspecies rubidus or a mutant thereof. The new antibiotics are active against a variety of microorganisms and are also useful in treating tuberculosis.
