Process for enzyme immobilization and products obtained thereby

The subject invention concerns an improved method of enzyme immobilization using polysulfonium salts. Some of the polysulfonium salts, advantageously, can be used to both flocculate and crosslink microbiologically-produced enzyme or cellular materials containing the enzymes. In such instances, the i...

More Information
Summary:The subject invention concerns an improved method of enzyme immobilization using polysulfonium salts. Some of the polysulfonium salts, advantageously, can be used to both flocculate and crosslink microbiologically-produced enzyme or cellular materials containing the enzymes. In such instances, the immobilization process is highly cost-efficient. The replacement of the prior art crosslinker of choice, glutaraldehyde, with a polysulfonium salt results in greater retention of enzyme activity during the immobilization process.
