Description
Background/Introduction: Acidic protease (ACP) can act on interior bond -C-NH- to hydrolyze the proteins of vegetable and animal in acid environment to form small peptides and amino acidics. The addition of this product to the processing of alcohol and distilled spirit can promote the growth of yeast to accelerate fermentation speed and improve alcohol productivity. In feedstuff industry, this product can be used as an additive by combined with other enzymes (such as cellulase, pectinase and beta-glucanase, etc) for the preparation of complex feedstuff enzymes. It can further improve the nutrition value of feedstuff to accelerate the growth and increase the weight of livestock and poultry. The assay is initiated with the enzymatic catalysis of casein by ACP in acid environment. The enzyme catalysed reaction products can be measured at a colorimetric readout at 680 nm
