A macrolactam disaccharide isolated from an antimicrobial complex 530 produced in fermentation under controlled conditions using a biologically pure culture of the microorganism Actinomadura fulva subsp. indica ATCC 53714.

Antimicrobial compound isolated from Actinomadura fulva subsp indica

A microorganism of the genus Acetinoplanes produces a novel complex of polyene antibiotics herein designated collectively Antibiotic 67-121 (and sometimes referred to as the Antibiotic 67-121 complex). The individual components are designated Antibiotic 67-121A, Antibiotic 67-121B, Antibiotic 67-121C and Antibiotic 67-121D. The individual components have ultraviolet spectra characteristic of heptaenes. Further, they are orally active against a variety of strains of Candida albicans including many clinical isolates thereof.

Antibiotic 67-121, a new polyene antifungal antibiotic produced by

The microorganisms Micromonospora inyoensis 1550F-1G and M. purpurea strain 1124 each microbiologically convert tobramycin, kanamycin A, kanamycin B and dibekacin to their respective 3'-N-methyl and 3'-N-methyl-4'-C-methyl derivatives. The derivatives exhibit significant activity against representative gram positive and gram negative bacteria and may also be converted to other derivatives which have significant antibacterial activity.

Microbiological methylation of aminoglycosyl-aminoglycosides

Rosaramicin, (also known as rosaramicin) a new broad spectrum antibiotic is described together with methods for its production via the cultivation under controlled conditions of Micromonospora rosaria, a new species of Micromonospora, and to methods for purifying and using the same. Its 2'-monoesters and its 3,2'-diesters and their acid addition salts also possess antibiotic activity.

A microorganism of the genus Actinoplanes produces a novel complex of polyene antibiotics herein designated collectively Antibiotic 67-121 (and sometimes referred to as the Antibiotic 67-121 complex). The individual components are designated Antibiotic 67-121A, Antibiotic 67-121B, Antibiotic 67-121C and Antibiotic 67-121D.

Antibiotic 67-694, (also known as rosamicin) a new broad spectrum antibiotic is described together with methods for its production via the cultivation under controlled conditions of Micromonospora rosaria, a new species of Micromonospora, and to methods for purifying and using the same. Its 2'-monoesters and its 3,2'-diesters and their acid addition salts also possess antibiotic activity.

Rosamicin esters, acid addition salts and methods for production thereof

Micromonospora arborensis produces a plurality of antibiotics named herein antibiotic 68-1147 complex, when cultivated under controlled aerobic conditions. Two of the antibiotics, antibiotic 68-1147 I and antibiotic 68-1147 II are described and shown to be effective antibacterial agents, especially against gram positive bacteria.

Antibiotic complex from micromonospora arborensis

Micromonospora inyoensis strain 155OF-1G NRRL 5742 is incapable of producing antibiotics unless an aminocyclitol is added to the fermentation medium. When such a compound is added, antibiotics are produced, said antibiotics being analogs of known aminoglycoside antibiotics differing therefrom with respect to the aminocyclitol subunit.

Methods for the preparation of semi-synthetic aminocyclitol

Micromonospora inyoensis strain 1550F-1G NRRL 5742 is incapable of producing antibiotics unless an aminocyclitol is added to the fermentation medium. When such a compound is added, mutamicins are produced, said mutamicins being analogs of known aminoglycoside antibiotics differing therefrom with respect to the aminocyclitol subunit.

Semi-synthetic aminocyclitol aminoglycoside antibiotics and methods for

A novel actinomycete herein designated Micromonospora zionensis elaborates a product having substantial antibacterial activity, said activity being due to sisomicin and the novel antibiotic substance coproduced therewith. The disclosure sets forth methods for producing, isolating and using the antibiotics.

Antibiotic G-52 and method for the production thereof

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.

Antibiotic G-418 and the production thereof

A novel composition having antibiotic activity is produced by fermentation of the new species of microorganism, Micromonospora grisea. The antibiotic complex is composed of four components, Verdamicin I, sisomicin, Antibiotic G-418, and gentamicin A, of which Verdamicin I is a novel basic antibiotic possessing a broad antibacterial spectrum. The other components have been produced previously.
