[Streptomyces spheroides M8-2 strain--a producer of extracellular proteolytic enzymes possessing fibrinolytic and thrombolytic action].

: Strain Streptomyces spheroides M8-2 was obtained as a result of ultraviolet light action on the S. spheroides spores strain 35. The mutant is characterized by the considerable increase (in 4-5 times) of the extracellular proteolytic enzymes which are able to dissolve fibrin and thrombs. The description of the morfologic, cultural and physiologic-biochemical properties of the culture is given. The content of GC-pairs in DNK of the mutant and parent strains has been determined.
