IMMOBILIZATION OF BIOACTIVE MATERIALS

摘要

An immobilised bioactive material for use in an industrial process is made by spraying an active proteinaceous coating together with a crosslinking agent on to a fibrous organic support. Woven cotton provides good strength, a large surface area with interstices, and food process compatibility. Advantages of the finished component include simplicity, good retention of the bioactive material upon the support, and retention of a useful amount of activity. A process for removal of lactose from cows' milk uses immobilized beta-galactosidase (EC 3.2.1.23) mixed with bovine serum albumin, cooled, mixed with glutaraldehyde, then sprayed onto a loose cotton cloth.
