[Isolation and properties of antibiotics from Streptomyces isolated from soils of Ukraine]
Abstract:
Thirteen antibiotics of red, rose, yellow and violet color, which are synthesized by the soil Streptomycetes on the complete corn-bean medium have been isolated and purified by means of thin layer chromatography. Antibiotic activity of the obtained compounds has been determined against a series of gram-positive and gram-negative microorganisms, and also yeasts. The maxima of absorption of antibiotics in visible and UV-light were established. The preliminary results are obtained about the presence of sugar component in the structure of molecules, as well as the indicator properties of the red-color antibiotics. The assumption was proposed about the affinity of some antibiotics for anthracyclines and ansamycines.
