| Summary | The acid protease catalyzes the hydrolysis of protein under acid condition to liberate more amino nitrogen. Combined with yeast growth promoters in the product, it reduces fermentation time and improves ethanol yield, bringing economic benefits. |
| Description |
The acid protease in Yeast Promoter is produced through submerged fermentation of Aspergillus niger, followed by purification and formulation. This enzyme facilitates the hydrolysis of proteins under acidic conditions. In the alcohol fermentation industry, it helps release more amino nitrogen, which enhances yeast growth and boosts ethanol yield, thereby providing economic benefits. The acid protease breaks down peptide bonds in proteins present in raw materials, producing short peptides and amino acids essential for yeast growth. This action reduces fermentation time, increases ethanol yield, and optimizes the use of raw materials. Additionally, it minimizes waste discharge and reduces the need for supplemental yeast nutrients, leading to cost savings. |
| Advantages |
Acid protease liberate more amino nitrogen Promotes yeast growth and fermentation Increase alcohol or ethanol yield Reduce fermentation time |
| Application | Used in fermentation to increase amino nitrogen level and boost fermentation |
| Application Area |
Ethanol Brewing Amino acid fermentation Organic acid fermentation Portable alcohol |
| Application Recommendation | The recommended dosage is 180-200 mL of the enzyme preparation per ton of total molasses materials or 100-180 mL of the enzyme preparation per ton of total corn 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. |
