The acid protease in Yeast Promoter JMCJ - 001 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. Besides, the product contains beneficial components for yeast growth.
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 fermentation time is
reduced, and ethanol yield is increased, while making the best use of raw
materials, having less waste discharge and saving cost for supplementation of
yeast nutrients.
