Identification of a Bacillus sp. Strain with Fibrinolytic Activity and Primary Study on Fermentation Process

Abstract:

An extracellar fibrinolytic strain was isolated from fermented shrimp paste. In addition to general physiological and biochemical properties, the strain was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain had high similarity with AY601723 and AB195282, suggesting that the strain is a subspecies of Bacillus sp. It was named as Bacillus sp. nov. SK006 by CCTCC. The medium composition and fermentation conditions for fibrinolytic enzyme production were also optimized in the research.
