Table 2 Immobilization efficiency of lipase on chitosan beads

From: Lipase from Rhizopus oryzae R1: in-depth characterization, immobilization, and evaluation in biodiesel production

Immobilization method FU (U/mL) IU (U/mL) RUS (U/mL) AY (%) IE (%)
Direct adsorption 210 175.4 29.3 83.5 97.1
Adsorption-crosslinking 210 192.7 15.5 91.8 99.1
  1. FU free units, IU immobilized units, RUS retained units in solution, AY activity yield, IE immobilization efficiency = (IU)/(FU-RUS) × 100
