    摘要: New antiviral agent U-50,228 and derivatives thereof, produced by the controlled fermentation of the known microorganism Streptomyces platensis var. clarensis var nova, NRRL 8035. This antiviral agent and its derivatives are active against DNA-viruses, for example, the Herpes virus and, thus, can be used to control such virus where its presence is not desired. For example, U-50,228 and its derivatives can be used to swab laboratory benches and equipment in a virology laboratory to eliminate the presence of Herpes virus.

    摘要: Microbiological process for preparing the known antibiotics, antibiotic A-396-1 and L-dihydrophenylalanine, by use of the new microorganism Streptomyces lemensis, NRRL 8170 using controlled fermentation conditions. These antibiotics are active against Gram-positive and Gram-negative bacteria. Accordingly, they can be used in various environments to eradicate or control such bacteria.

    摘要: Novel and useful ribonucleotides of analogs of the well known antibiotics lincomycin and clindamycin. These ribonucleotides are unexpectedly highly active against Streptococcus hemolyticus and Staphylococcus aureus in vivo. These ribonucleotides are prepared by using resting cell or cell-free extracts of Streptomyces rochei, NRRL 3533, or cell-free extracts of Streptomyces coelicolor, NRRL 3532.

    摘要: Antibiotic 10381a1, wherein R is hydrogen, is a cytosine-containing antibiotic producible by culturing the novel microorganism Streptomyces arginensis in an aqueous medium and isolation thereof. Derivatives wherein R is a C1 to C3 alkyl ester of antibiotic 10381a1, are also disclosed along with the pharmaceutically acceptable salts of both the native and esterified forms. Antibiotic 10381a1 inhibits the growth of selected species of yeast, fungi and bacteria. This invention also relates to a novel process for the preparation of the antibiotics 10381b and to a method of using antibiotics 10381b to promote growth in meat-producing animals. These antibiotics are also obtained by the fermentation of a nutrient medium with the novel microorganism Streptomyces arginensis and are active against selected species of bacteria.
