Lipase adsorption efficiency

The lipase adsorption efficiency was also affected by the pH of the adsorption medium. Ilie swelling degrees of the crosslinked PAA/PVA fibrous membrane (3.5 COOH/OH molar ratio) in lipase solution (5.0 mg/ml) increased from 6 to 25 with increasing pH fi om 2 to 7 (Figure 3b), which were 10 to 20% lower than those in pH buffer alone (Figure 3a). This may be because the lipase...
