Wide Range

Lipases are ubiquitous enzymes whose physiological role is the hydrolysis of triacylglycerol into fatty acids. They are the most studied and industrially interesting enzymes, thanks to their versatility to promote a plethora of reactions on a wide range of substrates. In fact, depending on the reaction conditions, they can also catalyze synthesis reactions, such as esterification, acidolysis and transesterification. The latter is particularly important for biodiesel production. Biodiesel can be produced from animal fats or vegetable oils and is considered as a biodegradable, non-toxic and renewable energy source. The use of lipases as industrial catalysts is subordinated to their immobilization on insoluble supports, to allow multiple uses and use in continuous processes, but also to stabilize the enzyme, intrinsically prone to denaturation with consequent loss of activity. Among the materials that can be used for lipase immobilization, mesoporous silica nanoparticles represent a good choice due to the combination of thermal and mechanical stability with controlled textural characteristics. Moreover, the presence of abundant surface hydroxyl groups allows for easy chemical surface functionalization. This latter aspect has the main importance since lipases have a high affinity with hydrophobic supports. The objective of this work is to provide an overview of the recent progress of lipase immobilization in mesoporous silica nanoparticles with a focus on biodiesel production.

Optimized Conditions

Metal–organic frameworks (MOFs) are an attractive class of hybrid materials with metal clusters and organic linkers. The unusual properties of MOFs, such as permanent nanoscale porosity, high surface area, uniformly structured cavities and the availability of in-pore functionality and outer-surface modification, are advantageous using as lipase immobilization platform. Herein, we covalent immobilized CALB onto MOFs and then evaluated the biocatalyst performance in the esterification of oleic acid with methanol for biodiesel production. Experimental data about the methanolysis process was evaluated by response surface methodology. The highest yield of 98.9 ± 0.4% was obtained under the optimized conditions: methanol/oil ratio of 3.65:1, a reaction temperature of 46.3 °C, a CALB@MOF loading of 117.77 mg and a reaction time of 11.55 h, which was closed to the predicted value (100.00%). Verification experiment confirmed the validity of the predicted model.
