| Abstract: | In this study, the effect of surfactants (Tween-80 and Acetonitrile) inclusions in the culture medium of Bacillus subtilis on the yield and characteristics of extracellular protease was investigated. The results showed that addition of Tween-80 increased the enzyme yield by 5 folds and thermal stability from 50oC to 60oC. Tween-80 did not affect the optimum pH, KM and VMax values as well as the enzyme efficiency. Acetonitrile shifts the optimum pH from 8 to 7 and reduced the affinity of the enzyme for casein. The selection of appropriate surfactants for Bacillus subtilis culture is required for optimum protease production. |
