Abstract:
The current work deals with downstream processing of lactoperoxidase using liquid emulsion membrane from the bovine milk whey, which is a by-product from dairy industry. It is an alternate separation technique that can be used for the selective extraction of lactoperoxidase. The extraction of lactoperoxidase in liquid emulsion membrane takes place due to the electrostatic interaction between the enzyme and polar head group of reverse micellar surfactant. The optimum conditions resulted in 2.86 factor purity and activity recovery of 75.21%. Downstream processing involving liquid emulsion membrane is a potential technique for the extraction of lactoperoxidase from bovine whey.
