  • industrial enzymes
    • function
      • specificity: they can catalyse reactions between specific chemicals. this is good because less products are formed, less purification needed
      • temperature: enzymes function well at low temperatures saving money.
    • immobilizing enzymes
      • they continue to catalyse enzyme controlled reactions, but do not mix freely
      • advantages
        • purification costs are low
        • immediately available for reuse
        • more stable because of matrix
      • disadvantage
        • requires additional time
        • less active
        • contamination is costly
    • techniques
      • covalent bonds: cross linking agents cross link enzymes together covalently
      • entrapment: enzymes are trapped in gel bead or network of cellulose fibres
      • membrane separation: permeable membrane separate enzymes
