  • immobilizing enzymes
    • entrapment
      • enzymes are trapped in network of cellulose fibres or gel beads. substrate molecules can pass through this material but the enzyme cannot
    • adsorbtion
      • enzymes adsorbed onto surface of support substance (e.g. clay) through ionic interactionsand hydrophobic interactions
    • covalent bonding
      • enzymes covalently bonded to each other and to an insoluable support
    • membrane separation
      • enzymes physically separated by partially permeable membrane. substrate can pass through membrane but enzyme cannot
