| 20110287509 | STABLE BIOCATALYSTS OF PENICILLIN ACYLASE AS GEL AGGREGATES AND THE PROCESS OF MANUFACTURE THEREOF - The present invention provides a stable and viable biocatalyst with high activity and operational stability and method of immobilization thereof. The immobilization process is based on the principle of entrapment of partially purified enzyme precipitate which is simultaneously aggregated by cross linking agent like glutaraldehyde and further entrapped in a combination of natural polymer like gelatin and synthetic polymer like polyvinyl alcohol with effective gelation under mild conditions of temperature and pH, resulting in a stable biocatalyst. The enzymes immobilized by the above process include Penicillin acylase from r | 11-24-2011 |
