PRODUCT DESCRIPTION
acid protease PRA100L is produced by submerged fermentation of Aspergillus niger followed by purification and formulation. The enzyme catalyzes the hydrolysis of protein under acid condition. In alcohol fermentation industry the product will liberate more amino nitrogen and improve ethanol yield by boosting yeast’s growth, bringing economic benefits.
MECHANISM
The acid protease is capable of breaking down peptide bonds in proteins in raw materials, liberating short peptides and even amino acids that are necessary for yeast’s growth. In this way ethanol yield is increased, while making the best use of raw materials and saving cost for supplementation of yeast nutrients.

APPLICATION RECOMMENDATION
The recommended dosage is 0.05-3kg of the enzyme preparation per ton of total raw materials. The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.
SAFE HANDLING PRECAUTIONS
Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
WARNINGS
Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
