Product Description

Yeast Promoter enzyme for ethanol industry


Sunson 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.


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.

1. Increase the number of yeast cells and the rate of germination, accelerate the fermentation, and shorten the fermentation cycle .

2. Yeast transformed sugar alcohol to improve the ability to improve the fermentation liquor end parts, reduce the production cost.

3. 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

1. It completely replaces nutrient salts such as urea and ammonium sulfate on molasses alcohol, and partially replaces urea and ammonium sulfate on corn alcohol.

2. 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 .

3. 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 .

The recommended dosage is 180-200 ml of the enzyme preparation per ton of total molasses materials and dosage is 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.
