2. Dosage
The dosage of acid protease used is ****6 U/g raw materials; it depends on different raw material and fermentation process. In most cases, each gram raw material need *4U/g acid protease, **0g/ton acid protease (****0u/g), or **0g/tone acid protease (****0u/g).

3. Application
(1) Re-activation of acid protease: dissolve the acid protease in ****0 warm water, soak and activate for 1 hour, stir every *5 minutes.
(2) Batch fermentation: when the sacrificed slurry reaches 1/3 of the fermentation tank, add all liquid and residues part at one time.
(3) Cascade fermentation and semi-continuous fermentation: Depends on the production volume, add acid protease continuously during fermentation. For a *0 ton/day (*0,**0 ton/year) alcohol plant, the adding rate acid protease is *0 liter/ hour.

4. Others
(1) As the optimum temperature of acid protease is ~ *0, it is suggested to use the thermo yeast.
(2) The use of acid protease can shorten the fermentation cycle greatly to *****5 hours. After fermentation, discharge the tank immediately; avoid alcohol lost and increase of acidity.
(3) After the use of acid protease, the number of yeast will doubled, fermentation speed will greatly increase, so its better to control the fermentation temperature, the highest temperature should not be more than *0.
