Summary
Immobilizing proteases from Str. griseus actinomycete on aminoethyl cellulose altered enzyme activity ratios but not stability optima. The immobilized enzyme showed significant activity loss after repeated use.
Area of Science:
- Biochemistry
- Enzymology
- Microbial Biotechnology
Context:
- Protease enzymes are crucial in various biotechnological applications.
- Immobilization is a technique used to enhance enzyme stability and reusability.
- Str. griseus actinomycete is a source of valuable proteolytic enzymes.
Purpose:
- To immobilize the protease complex from Str. griseus actinomycete using glutaraldehyde and aminoethyl cellulose.
- To evaluate the impact of immobilization on the enzyme's activity, stability, and reusability.
Summary:
- The protease complex from Str. griseus actinomycete was successfully immobilized onto aminoethyl cellulose via glutaraldehyde cross-linking.
- Immobilization altered the specific activity ratios of the peptide hydrolase system but maintained the pH optimum for total proteolytic activity and stability.
- No significant overall stabilization of the enzyme complex was observed, with a 40-60% activity loss after five reuse cycles.
Impact:
- This study provides insights into the challenges of enzyme immobilization for industrial applications.
- Understanding the changes in enzyme activity and stability post-immobilization is critical for optimizing biocatalytic processes.
- The findings highlight the need for further research into improving the reusability and stability of immobilized microbial proteases.
