摘要

PROCEDURE FOR OBTAINING Modifiers biological responses activity RECUPERADORA HAEMATOPOIETIC FUNCTION FROM equal and indistinctly, TWO N2 fixers BACTERIAL STRAINS Azotobacter Azotobacter vinelandii chroococcum Y. The invention describes the preparation process of two preparations obtained from pure cultures of Azotobacter STRAINS SELECTED AND Azotobacter vinelandii chroococcum RESPECTIVELY AND FUNCTION PROPERTIES hematopoietic stimulatory. This procedure consists in the growth of corresponding culture BACTERIANO, obtaining a fraction F1 or part thereof CELLULAR obtained in cell supernatant CROP AFTER SHOCK TREATMENT ACID-BASIC TO, PRODUCING A FRACTION F2 or part thereof exocellular OBTAINED BY TREATMENT WITH IRON METAL culture supernatant, freeze-drying of both fractions CONCENTRATION dEFINED FOR EACH OF THEM. PREPARATION THUS OBTAINED is provided ACTIVITY ACTIVITY stimulatory hematopoietic system and is orally active. It has application for human and veterinary use.
