Effect of compressed fluids treatment on the activity of inulinase from Kluyveromyces marxianus NRRL Y-7571 immobilized in montmorillonite

► Influence of pressurized fluids, propane and LPG, treatment on the enzymatic activity of inulinases. ► Stability of the enzyme after high-pressure pre-treatment was experimentally monitored. ► Enhanced enzyme activity was verified for high-pressure treated enzymes in propane and LPG.
