发酵菌

The protease secreted from cellcould be more stable by adding the Ca2+ to fermentation broth. The cold-adapted protease, stable at 15℃, could be secreted in large quantity by the strainof SYP-A3-2. When the culture temperature was changed from 15℃ to 20℃, the strain grewfaster while the enzyme yield was decreased.
