Applications of Super Alcohol Active Dry Yeast (Starch Base):
Our active dry yeast is suitable for the fermentation of starch-based rawmaterials like corn, wheat and cassava etc. while producing alcohol and fuelethanol etc..

Features of SuperAlcohol Active Dry Yeast (Starch Base):
1. Ethanol tolerance: 23%(v/v); for its high ethanoltolerance, it is suitable for high concentration alcohol fermentation and fuelethanol fermentation.
2. Thermal tolerance: 82OF-108 OF (2842);
Optimal fermenting temperature: 90OF-93 OF (3234);
3. PH value tolerance: 3.5-5.5;
Optimal fermenting PH value: 4.5-5.5
4. Shorter alcohol fermentation period:
Batch fermentation: 60-65 hours;
Continuous fermentation: 55-60 hours;
5. Our super alcohol active dry yeast is suitable for thick mash fermentationand the thick mash fermentation has the following advantages:
(1) Reduced steam consumption;
(2) Reduced the consumption of process water and saved waste waterdisposal cost.
(3) Improved equipment utilization rate.
6. High reproduction performance and fermenting speed;

Usages of SuperAlcohol Active Dry Yeast (Starch Base):
1. Inoculated fermentation (Batch fermentation):
One liter of mesh is suitable for inoculated fermenting of 0.25-0.3g dryyeasts;
The initial cell concentration of mesh: 5 millions/ml;
2. Expanding culture:
The nutrients needed during spreading culture: nitrogen source; phosphorussource; magnesium ion, zinc ion etc.;
The inoculated yeast should be changed every 72 hours.

Note:
Optimum culture conditions for Super Alcohol Active Dry Yeast (StarchBase):
