title: [Antibiosis shown by a strain of Byssochlamys nivea Westling, 1909. III. Chromatographic characteristics and isolation of the active fraction].
abstract: Early papers revealed that culture filtrate of Byssochlamys nivea has antibiotic properties. Active filtrate of B. nivea is extracted with ethyl acetate. Paper chromatography is carried out on Whatman no. 1; thin-layer chromatography is carried out on Kieselgel; visualization with bioautographic technique reveals a single spot. Ethyl acetate extract is passed through silicic acid-celite column. Each isolated fraction is tested for antibiotic activity. Only one supports this activity; a crystallized matter, melting point 109-110 degrees C, thermostable, is obtained.
