Steady state yields of biodiesel in the lipase-immobilized silica monolith bioreactor. The yields are shown as a function of W/v (mass of lipase divided by flow rate of substrate solution). The substrate solution, composed of methanol and oil at 3:1 molar ratio and 0.6% (w/w) water, was fed continuously at constant flow rates between 0.6 mL/h and 30 mL/h to the bioreactor (10 mm × 30 cm) loaded with 4.92 g silica monolith containing 1.67 g lipase.
