Summary
This study introduces a dual-enzyme process to purify trehalose from maltose. Immobilized glucoamylase converts residual maltose to glucose, which is then oxidized to gluconic acid for easier separation.
Area of Science:
- Biotechnology
- Enzyme Engineering
- Biochemical Engineering
Background:
- Trehalose purification from maltose is challenging due to glucose by-products and unreacted maltose.
- Efficient separation methods are crucial for industrial trehalose production.
Purpose of the Study:
- To develop a dual-enzyme process for improved trehalose purification.
- To investigate the use of immobilized glucoamylase for efficient maltose hydrolysis.
Main Methods:
- Immobilization of glucoamylase on CM Sepharose, optimizing reaction conditions (temperature, pH).
- Sequential enzymatic conversion: maltose to glucose (glucoamylase), glucose to gluconic acid (glucose oxidase).
Main Results:
- CM Sepharose showed high protein adsorption capacity for glucoamylase immobilization.
- Optimal conditions (40°C, pH 4.0) achieved complete maltose to glucose conversion in 35 min.
- The immobilized enzyme maintained high conversion efficiency over 80 cycles.
Conclusions:
- The developed process effectively converts residual maltose to glucose, facilitating trehalose purification.
- This enzymatic strategy shows promise for scalable industrial trehalose production.
