EFFECT OF PH&TEMP
Effect of pH
The effective pH range for the activity of AP-520 is approximately 2.0 to 6.0, with an optimum performance at pH 2.5 to 4.0.
Effect of Temp
The activity of AP-520 is effective in the range from 30°C to 65°C, with an optimum performance obtained at 30°C to 50°C. The exact temperature optimum will be influenced by several process variables including time, pH, and substrate nature and substrate concentration.

Effect of Temp
The activity of AP-520 is effective in the range from 30°C to 65°C, with an optimum performance obtained at 30°C to 50°C. The exact temperature optimum will be influenced by several process variables including time, pH, and substrate nature and substrate concentration.
EFFECT OF METAL IONS
AP-520 is activated by Mn2+, Ca2+ and Mg2+ ions. Heavy metal ions such as Cu2+, Hg2+ and Al3+ will inhibit the enzyme activity of AP-520.
USAGE
Application Guidelines
In intermittent fermentations, the entire dose of AP-520 should be added all at once after the fermentation tank is filled approximately 30%. In continuous fermentations, AP-520 should be added continually, with the dosage rate dependent on the amount of mash fed at the inlet of the fermentation tank.
Dosage Recommendations
The typical dosage rate for AP-520 is 0.01% to 0.02% w/w (dry solids basis) and this dosage level is recommended as a starting point for optimizing the enzyme dosage. The optimum enzyme dosage will be dependent on both the raw materials used (substrate nature and concentration) and the processing conditions.

SAFETY & HANDLING
Inhalation of enzyme dust and mists should be avoided. Proteins present in AP-520 may cause an allergic-type reaction in sensitized individuals which could necessitate immediate medical attention. In case of contact with the skin or eyes, promptly rinse with water for at least 15 minutes. For detailed handling information, please refer to the Material Safety Data Sheet.
