A Xtreptomyces strain, L23, isolated in our laboratories, produces a new antibiotic. This paper describes the characteristics of the strain, the method of fermentation and the preparation of the active substance in a crystalline form, and its chemical and biological properties. ## Experimental Th
## Abstract A new antibiotic NRC‐501 was ioslated from the fermentation broth of __Streptomyces spec__. NRC‐501. Physical, chemical, and biological characteristics of the antibiotic were studied.
An actively antibiotic producing actinomycete, Streptomyces NRC-101, was isolated from Egypt,ian soil. The strong mtibiotic effect of the fermentation broth of the microorganism on grampositive and gramnegative bacteria led t o experiments for the isolation of the active principle. After isolation a
