Catalog Number IE-1204
Physical Form Liquid
Color Brown
Dosage Parameters 0.05-300 g/T
Source Microorganism
| Summary | The acid protease catalyzes the hydrolysis of protein under acid condition to liberate more amino nitrogen that is more accessibe for yeast growth. Therefore, it can reduce fermentation time and improve ethanol yield, bringing economic benefits. |
| Description |
Acid Protease is produced through submerged fermentation of Aspergillus niger, followed by purification and formulation. This enzyme accelerates the hydrolysis of proteins under acidic conditions. In the alcohol fermentation industry, it enhances the release of amino nitrogen, which promotes yeast growth and improves ethanol yield, offering significant economic benefits. The acid protease breaks down peptide bonds in proteins found in raw materials, releasing short peptides and amino acids essential for yeast development. This process not only increases ethanol yield but also optimizes raw material usage and reduces costs associated with yeast nutrient supplementation. |
| Advantages |
Acid protease able to liberate more amino nitrogen Promotes yeast growth and fermentation Increase ethanol or alcohol yield Reduce fermentation time |
| Application | Used in fermentation to increase amino nitrogen level, speed up yeast growth and boost fermentation |
| Application Area |
Ethanol Brewing Amino acid fermentation Organic acid fermentation Portable alcohol |
| Application Recommendation | The recommended dosage is 0.05-300 g 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. |
