A strain of potential producer of fibrinolytic enzyme was isolated from Korean fermented food. The isolated bacterium was identified and named as Bacillus brevis KJ-23. The optimal condition of the medium for the production of fibrinolytic enzyme from Bacillus brevis KJ-23 was nutrient broth with 0.5% D-ribose, 0.5% malt extract and 0.3% $K_2$HPO$_4$. The optimum pH, temperature and fermentation time for the enzyme production were pH 7.0, 3$0^{\circ}C$ and 24 hr, respectively.
