Abstract

For studies of fibrinolytic enzyme strain K-54 was isolated from the Korean traditional food chungkook-jang. Isolated strains K-54 was identified as Bacillus subtilis. The molecular weight of fibrinolytic enzyme from B. subtilis K-54 was 27 kDa. Optimum temperature for fibrinolytic enzyme of B. subtilis K-54 was $50-70^{\circ}C$ and optimum pH for producing the enzyme of this strain was ranging from 8 to 12. Also, it was found out enzyme activity was completely inhibited by 1mM PMSF. The result indicated this enzyme was thermo-stable alkaline serine protease with strong fibrinolytic activity. The wool and silk were treated with protease of B. subtilis K-54. As a result, the property of dyeing of wool fabrics was increased. By the increasing of treatment time became smoothened. But the change of mechanical properties were not changed.
