Immobilized enzymes function
Witryna1 wrz 2024 · Cellulose-based matrices are expected to be ideal enzyme carriers due to their sustainability and biocompatibility. However, the linkages between immobilized enzymes and celluloses often suffer from low-density and non-biodegradability, leading to inefficient loading of enzymes as well as persistent generation of solid wastes after … WitrynaIn the 1970s Katchalski et al. [6] demonstrated that enzymes immobilized on surfaces and confined in cavities exhibit higher activity than in free solution. On the other hand, pH, immobilization time and protocol, surface coverage, and surface curvatures and chemistries can substantially impact the enzymatic activity of multimeric proteins [7].
