Fast multipoint immobilized MOF bioreactor.

Area of Science:

• Biotechnology
• Materials Science
• Enzyme Engineering

Background:

• Enzyme immobilization is crucial for bioreactor development.
• Existing methods often involve complex chemical modifications.
• Monitoring enzyme loading and distribution is challenging.

Purpose of the Study:

• To develop a novel enzyme-NBD@MOF bioreactor.
• To achieve high proteolytic performance with reusability.
• To establish a simple immobilization technique for enzyme monitoring.

Main Methods:

• Multipoint immobilization of enzyme-NBD onto a metal-organic framework (MOF).
• No chemical modification of the solid support was required.
• Fluorescence emission was used to monitor enzyme loading and distribution.

Main Results:

• The enzyme-NBD@MOF bioreactor exhibited excellent proteolytic performance.
• The bioreactor maintained its performance after successive reuse and storage.
• Enzyme loading and distribution were successfully monitored via fluorescence.

Conclusions:

• A rapid and simple multipoint immobilization technique was developed.
• The developed bioreactor offers superior proteolytic activity and stability.
• Fluorescence monitoring provides an effective way to assess enzyme loading in bioreactors.
