Enzyme Production Process
1. Enzymes are commonly produced on an industrial scale through fermentation using microorganisms like yeast, fungi, and bacteria.
2. Maintaining optimal conditions during fermentation (oxygen, temperature, pH, nutrients) is critical to prevent batch failure.
Filtration During the Process
• Fermentation Ingredients Filtration: It’s important to filter fermentation ingredients like water, nutrients, and chemicals to prevent microbial contamination, which can affect batch safety and quality.
• Liquid Filtration: Membrane filters are used to remove microorganisms and contaminants, ensuring high purity in the final product. Activated carbon filters
Post-Fermentation Filtration
After fermentation, several steps are involved in achieving high purity:
• Fermenter Broth Clarification: Ceramic crossflow filtration is used as a modern alternative to traditional methods like centrifugation or diatomaceous earth filtration.
• Enzyme Polishing and Sterile Filtration: This is performed before the enzyme is packaged.

FAQ
1. What role do Great Wall filter sheets play in enzyme production?
Great Wall filter sheets are designed for multiple filtration stages in industrial enzyme production, from clarifying fermenter broth to final sterile filtration. They ensure high purity, microbial reduction, and retention of solids while maintaining the enzyme’s activity and quality.
2. Why choose high-purity cellulose filter sheets for enzyme filtration?
High-purity cellulose filter sheets contain no added mineral filter aids, minimizing the risk of metal ion precipitation. They can handle acidic and alkaline environments, preserve the enzyme’s color and aroma, and reduce contamination risks.
3. Can these filter sheets handle high-viscosity liquids or high solid content?
Yes. These filter sheets are engineered for challenging filtration tasks, including high-viscosity liquids and broths with high solid loads. Their strong adsorption capacity and depth filtration design ensure excellent filtration efficiency.
4. How is product quality and traceability guaranteed?
Every filter sheet is manufactured under ISO 9001:2008 quality standards in a controlled environment. Each sheet is laser-etched with its grade, batch number, and production date, ensuring complete traceability from production to application.
