| Abstract: | Screening 30 strains from five different samples, we gained strain T-3 whose nattokinase activity could reach 3 158.97 IU/mL by the first selection and the second selection. According to morphological, physiological and biochemical characleristics, the bacillus subilits stain was identified. Strain T-3 has good tolerance to temperature, pH, gallbladder salt, and good generation stability. |
