Acid protease enzyme for ethanol industry ENZYMES.BIO
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.
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.

Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
