Yeast Promoter Enzyme for Molasses Ethanol Industry
Introduction
Enzymes.Bio Special Protease for Molasses or Corn Alcohol fermentation is made from Aspergillus niger through cultivation and extraction technique and then complex with yeast promoter. This product can catalyze the hydrolysis of protein under acid condition and can promote the functions of yeast.
Definition of Unit
1 unit of Acid Protease equals to the amount of enzyme, which hydrolyzes casein to get 1μg of tyrosine at 40℃ and pH3.0 in 1 min.

Function
- Increase the number of yeast cells and the rate of germination, accelerate the fermentation, and shorten the fermentation cycle.
- Yeast transformed sugar alcohol to improve the ability to enhance the fermentation liquor end parts, reduce the production cost.
- Reduce the residual sugars and eutrophic substance precursor material to reduce the vinasse drying process Maillard reaction, reducing the pressure on sewage treatment.
Product Uniqueness
- It completely replaces nutrient salts such as urea and ammonium sulfate on molasses alcohol, and partially replaces urea and ammonium sulfate on corn alcohol.
- Balance alcohol yeast nutrition (increasing cell number and germination rate), adjust yeast osmotic pressure (osmotic pressure determines sugar consumption), improve yeast high alcohol tolerance (lower sugar) and improve alcohol content.
- The alcohol can be increased 0.6-2.0% (v/v) when used in molasses alcohol; and the alcohol can be increased 0.3-0.6% (v/v) when used in corn alcohol.
Dosage
The recommended dosage is 180-200 ml of the enzyme preparation per ton of total molasses materials and 100-180 ml of the enzyme preparation per ton of total corn materials. However, the optimal dosage depends on the application criteria, the processing parameters being utilized, and the attributes desired in the hydrolysate being developed.
Package
*Package: 1 kg / bag.
Storage
*Storage: Keep sealed in a dry and cool place and avoid direct sunlight. Slight sedimentation is acceptable since it will not impact the performance of the product.
Shelf Life
*Shelf life: 12 months in a dry and cool place.
Safety
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
