Stabilization by Crosslinking of β‐Galactosidase Immobilized by Adsorption for Application in a Continuous Lactose Removal Process

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Adsorption is the simplest method of enzyme immobilization, but it often requires additional treatments to improve stability. These treatments, however, may impact enzymatic activity. This study investigated the effect of crosslinking on the stability of β‐galactosidase immobilized by adsorption on A‐568 resin and its implications for ...
