Product Description
DESCRIPTION
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 together with beneficial components for yeast
growth in the product reduces fermentation time and improves ethanol yield,
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 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.
