To study the activities and dynamic changes of fibrinolytic enzyme, standard fibrin plate was used to determine the fibrinolytic activity. For the first time fibrinolytic enzyme was found during the fermentation of SSP and the fibrinolytic activities of samples were shown to increase significantly over time. In the "yellow cladding" stage, the fibrinolytic activity was 619.75 IU/g. On day 6, 12 and 15 of the "secondary fermentation" stage, the fibrinolytic activity was 711.49 IU/g, 866.67 IU/g, 1 022.31 IU/g, respectively. The results indicate that fibrinolytic enzyme was generated during the fermentation of SSP and it displayed increasing activity which peaked at the "secondary fermentation" stage. The fibrinolytic enzyme was found to not only degrades fibrin directly, but also activate plasminogen to do so.展开更多
