[New producer of cephamycin C, Streptomyces filipinensis var. cephamycini var. nov].

An actinomycetes strain 3016 was isolated from a soil sample on a selective medium with actinomycin as a result of directed screening of organisms producing beta-lactam antibiotics. The culture fluid of the isolate contained an antibacterial anibiotic identical to cephamycin C. Description of the strain is presented. It is a representative of new variety of streptomyces filipinensis var. cephamycini var. nov. The results of the study of the chemical properties of antibiotic 3016 and its identification with cephamycin C are also presented.
