Improving the Thermostability and Optimal Temperature of a Lipase from the Hyperthermophilic Archaeon Pyrococcus furiosus by Covalent Immobilization

Figure 2

Surface response and contour lines for lipase immobilized on octyl-agarose (a) and on glyoxyl-agarose (b) as a function of temperature and pH. The enzyme immobilized on Octyl-agarose showed an optimal temperature of 66°C and pH around 7. The enzyme immobilized on glyoxyl agarose reached activities at temperatures as high as 90°C and pH 7.
